20220008182
This application relates to oral healthcare, and in particular, to devices and methods for maintaining oral hygiene, cleaning teeth, and/or freshening the mouth.
Oral hygiene is important for many reasons, including, for example, preventing dental decay and gum disease, and keeping breath fresh. Generally, people brush, floss, and use mouthwash to keep their mouth and teeth clean.
The features of the present disclosure will become apparent from the following description and appended claims, taken in conjunction with the accompanying drawings. Understanding that these drawings depict only several embodiments in accordance with the disclosure and are not to be considered limiting of its scope, the disclosure will be described with additional specificity and detail through use of the accompanying drawings.
Various features illustrated in the drawings may not be drawn to scale. Accordingly, the dimensions of the various features may be arbitrarily expanded or reduced for clarity. In addition, some of the drawings may not depict all of the components of a given system, method or device. Finally, like reference numerals may be used to denote like features throughout the specification and figures.
This application relates to oral hygiene and/or teeth cleaning devices and associated methods. The oral hygiene devices can be configured to have a shape that allows all or substantially all of a user's teeth (for example, all or substantially all of a user's upper teeth and/or all or substantially all of a user's lower teeth) to be cleaned at once. In some embodiments, the oral hygiene devices are configured to be useable, for example, without access to water or a bathroom. Thus, the oral hygiene devices can be used to freshen and clean the user's mouth on-the-go. In some embodiments, the oral hygiene devices are disposable.
The features, aspects, and advantages of the present application will now be further described with reference to the drawings of several embodiments, which are intended to be within the scope of the embodiments disclosed herein. These and other embodiments will become readily apparent to those skilled in the art from the following detailed description of the embodiments having reference to the attached figures, the development not being limited to any particular embodiment herein disclosed.
In the illustrated embodiment of
One or more of the inside surfaces of the upper channel 106 and the lower channel 108 may include features for cleaning the user's teeth (or otherwise freshening the user's mouth). For example, the inside surfaces of the upper channel 106 and the lower channel 108 can include bristles, foam, rubberized fingers, ribs, textured surfaces, etc., configured to clean the teeth when the oral hygiene device 100a is positioned within the mouth and moved back and forth and/or up and down. The teeth cleaning features are not shown in
In some embodiments, the teeth cleaning features within the upper channel 106 and the lower channel 108 are formed as part of the body 102. That is, in some embodiments, the teeth cleaning features can be integrally formed with the body 102. For example, the inside surfaces of the upper channel 106 and the lower channel 108 can be configured with a teeth cleaning texture that is molded into the body 102. In some embodiments, the teeth cleaning features can be made from the same material and/or formed at the same time as the body 102. For example, the body 102 and teeth cleaning features can be formed with a one-shot injection molding process in which a single material is injected into a mold to form the body 102 and teeth cleaning features simultaneously.
Advantageously, in some embodiments, the teeth cleaning features may comprise a different material than the body 102. For example, the teeth cleaning features may comprise a softer or more flexible material than the body 102. In such embodiments, the body 102 may be formed from a relatively stiffer or more rigid material in order to provide structural support for the device 100, and the teeth cleaning features can comprise a relatively more compliant or softer material in order to improve user comfort and cleaning efficiency. When made from different materials, the body 102 and the teeth cleaning features can be molded in a two-shot injection or overmolding process. For example, a first injection can be made using a first material to form the body 102, and then a second injection can be made using a second material to form the teeth cleaning features on the body 102.
The teeth cleaning features within the upper channel 106 and/or the lower channel 108 can be attached to the body 102 within the channels 106, 108. In the case of a two-shot injection or overmolding process, the teeth cleaning features are molded (and thereby connected) directly onto the body 102. In other embodiments, the body 102 and teeth cleaning features can be formed separately and then attached to each other, for example, with dental-grade adhesives.
In some embodiments, the upper channel 106 and the lower channel 108 can be lined with bristles, foam, rubberized fingers, ribs, etc., that are attached to the channels 106, 108. The shape, size, and combinations of the teeth cleaning features described herein are not limited to the above materials, but are selected for specific characteristics, including comfort to the mouth and gums and ability to clean teeth.
As illustrated in
To use the oral hygiene device 100a, the user may use the handle 110 to insert the oral hygiene device 100a into his or her mouth. The user may position the oral hygiene device 100a such that the user's upper teeth are positioned within the upper channel 106 and the user's lower teeth are positioned within the lower channel 108. In this position, the upper and lower channels 106, 108 may contact the front, bottom, and back surfaces of the user's upper teeth and the front, top, and back surfaces of the user's lower teeth. Further, because of the generally U-shaped body the device 100a can contact all or substantially all of the user's upper and/or lower teeth. As used herein, “contacting substantially all of the user's upper and/or lower teeth” can refer to contact at least 50%, at least 60%, at least 70%, at least 80%, or at least 90% of the user's upper and/or lower teeth.
With the oral hygiene device 100a positioned within the mouth, the handle 110 may extend out of the user's mouth between the user's lips. Using the handle 110, the user may manipulate the oral hygiene device 100a by moving the handle 110 back and forth (e.g., side to side or right and left) and/or up and down. Manipulating the oral hygiene device 100a in this manner causes the teeth cleaning features within the upper channel 106 and the lower channel 108 to clean the teeth. After the user has used the device 100a to clean the teeth, which can be done for an indicated period of time, for example, 10 seconds, 15 seconds, 20 seconds, 30 seconds, 1 minute, 1.5 minutes, or 2 minutes, the user can remove the oral hygiene device 100a from the mouth. In some embodiments, the oral hygiene device 100a is disposable, and can then be discarded.
Notably, in some embodiments, the oral hygiene device 100a can be configured for use without requiring water. As such, the oral hygiene device 100a can be used generally anywhere to quickly clean and/or freshen up the user's mouth, without requiring the user to access a bathroom or running water. To this end, the oral hygiene device 100a can include dabs of mouthwash, breath freshener, toothpaste, desensitizing paste or gel as described below with reference to
Similar to the description above, one or more of the inside surfaces of the channel 114 may include features for cleaning the user's teeth. For example, the inside surfaces of the channel 114 can include bristles, foam, rubberized fingers, ribs, textured surfaces, etc., configured to clean the teeth when the oral hygiene device 100b is positioned within the mouth and moved back and forth and/or up and down. As described above, the teeth cleaning features can be formed as part of the body 102, molded onto the body in a two-shot injection or overmolding process, or attached to the body 102 within the channel 114 and can be made of the same or different materials than the body 102.
With the generally U-shaped cross-sectional profile 114, the oral hygiene device 100b can be configured to clean either the user's upper teeth or the user's lower teeth at a time. In some instances, the device 100b can then be flipped over to clean the other of the user's upper teeth or the user's lower teeth. For example, the user may use insert the oral hygiene device 100b into the mouth such that the channel 114 is oriented in an upward direction and the user's upper teeth can be received within the channel 114. The user may then use the handle 110 to manipulate the device to allow the teeth cleaning features within the channel 114 to clean the user's upper teeth. The user may then remove the oral hygiene device 100b, flip the device over (such that the channel 114 opens in a downward direction), and reinsert the device such that the user's lower teeth are received within the channel 114. The user may again manipulate the device 100b such that the teeth cleaning features clean the user's lower teeth. Alternatively, the user may use the device 100b to clean the lower teeth first, followed by the upper teeth. In some instances, the user may use two of the devices 100b, one to clean the user's upper teeth and one to clean the user's lower teeth.
In some embodiments, the oral hygiene device 100b may include teeth cleaning features positioned on a side 116 of the body 102 opposite the channel 114. With reference to the illustrated orientation, the side 116 may be the lower or bottom side of the device. For example, in addition to including teeth cleaning features within the channel 114, the oral hygiene device 100b may also include teeth cleaning features (e.g., bristles, ribs, rubberized figures, foam, etc.) that extend from the lower side 116. Thus, in some embodiments, the oral hygiene device 100b (with its generally U-shaped cross-sectional profile 112) can be configured to clean both the upper and lower teeth of the user at the same time.
With reference to
The body 202 may be made of a rigid, semi-rigid, or flexible material, such as plastic, rubber, a polymer, or other suitable material. In some embodiments, the body 202 is rigid enough to provide general support and shape for the oral hygiene device 200, while remaining flexible enough to allow the body 202 to fit to the particular anatomy of the user's mouth and teeth. In some embodiments, the body 202 comprises a thermoplastic elastomer (TPE), high-density polyethylene (HDPE), polypropylene (PP), low-density polyethylene (LDPE), polyamides, polyolefin or other resins, polychloro-trifluoroethylene, various thermoplastics, and/or various elastomers. In some embodiments, the body 102 may comprise a food grade polypropylene. The composition of the body 202 is not limited to the above materials, but is selected for specific characteristics including enough rigidity to provide general support and shape for the oral hygiene device 200, while including enough flexibility to allow the body 202 to fit to the particular anatomy of the user's mouth and teeth.
The body 202 may be formed such that the walls (e.g., the inner wall 220, the outer wall 222, and the bottom wall 224) are sufficiently thin so as to allow the body 202 to flex and conform to the shape of the user's mouth. For example, in some embodiments, the walls of the body 202 are about 2 mm, 1.5 mm, 1.0 mm, 0.75 mm, 0.5, or 0.25 mm thick. In some embodiments, the nominal thickness of the walls of the body 202 is about 1.2 mm. These thicknesses are provided by way of example, and the thickness of the walls of the body 202 can be selected to provide the desired characteristics described throughout this application.
In some embodiments, the oral hygiene device 200 can be provided in a variety of sizes (e.g., small, medium, large, adult, or child) configured for use by users that have different size mouths. In some embodiments, the oral hygiene device 200 can be provided in a size that is generally configured to fit most mouth sizes.
As illustrated, the oral hygiene device 200 includes a handle 210. The handle 210 can be configured as a tab, although other shapes are possible as described in greater detail below (see, for example,
Similar to the oral hygiene devices 100a, 100b described generally above, the oral hygiene device 200 can include teeth cleaning features (such as ribs 218) configured to clean the user's teeth when the device is used. In the illustrated embodiment, the teeth cleaning features comprise the ribs 218, although in other embodiments, other types of teeth cleaning features (e.g., foam, bristles, textured surfaces, etc.) can be used in addition to or in place of the ribs 218.
The ribs 218 can be formed of the same material as the body 202, or the ribs 218 can be formed of a softer or more flexible material than the body 202 as described above. Advantageously, forming the body 202 and the ribs 218 of different materials may improve functionality, comfort, and efficiency of the device. For example, as described above the body 202 can be formed of a generally stiffer and more rigid material to provide structural support for the device 200, while the ribs 218 can be formed of a generally less rigid or softer material. The softer material of the ribs 218 can provide more user comfort during use, while also better conforming to the user's mouth and teeth shape to provide increased cleaning efficiency.
The ribs 218 can be integrally formed with the body 202 or can be separately formed and attached to the body 202. In some embodiments, the body 202 and ribs 218 are co-molded in a two-step molding process, such as a double shot or overmolding process, as described above. In other embodiments, the body 202 and the ribs 218 can be formed separately and then attached to one another. In some embodiments, the ribs 218 comprise a thermoplastic elastomer (TPE), silicon rubber, high-density polyethylene (HDPE), polypropylene (PP), low-density polyethylene (LDPE), polyamides, polychlorotrifluoroethylene, various thermoplastics, and/or various elastomers. In some embodiments, the ribs 218 comprise a food grade TPE or thermoplastic polyurethane (TPU). The composition of the ribs 218 is not limited to the above materials, but can be selected for specific characteristics including the ability to clean on and around teeth. In some embodiments, the ribs 218 may comprise a material with a Shore A hardness of between 70 and 100, between 75 and 95, or between 80 and 90, or between 85 and 90. Shore A hardnesses within these ranges can provide the comfort and efficiency advantages discussed above.
In the illustrated embodiment, the oral hygiene device 200 includes ribs 218 positioned both in the channel 216 and extending from the bottom wall 224 of the body 202 so that the ribs 218 can contact the user's upper and lower teeth at the same time. Such an embodiment can advantageously reduce the total time required to freshen the mouth or clean the teeth be cleaning both the top and bottom teeth simultaneously. In some embodiments, the oral hygiene device 200 may include ribs 218 on only one side of the body 202 (e.g., the upper side or the lower side).
In some embodiments, the shape of the ribs 218 can be formed in order to contour to a user's mouth and teeth. In some embodiments, the ribs 218 are about 1.2 mm, 1.0 mm, 0.8 mm, 0.6 mm, or 0.5 mm thick, although other thicknesses, both thinner and thicker than these example values are possible. The thickness can be selected to facilitate teeth cleaning efficiency.
In some embodiments, the size and shape of the ribs 218 varies depending upon the location of the ribs 218 on the body 202. For example, the size and shape of the ribs 218 can be adjusted to suit the general size and shape of the particular teeth the ribs 218 will generally overlie when the oral hygiene device 200 is positioned within the mouth. Ribs 218 that are positioned on the body 202 to generally overlie molars (which are generally thicker) may have a different shape than ribs 218 that are positioned to overlie incisors (which are generally thinner). The ribs 218 can also be configured such that they contact more than one surface of the user's teeth at a time. For example, the ribs 218 can be configured to contact the front, bottom and back surfaces of the user's upper teeth and/or the front, top, and back surfaces of the user's teeth simultaneously.
The ribs 218 may also have a shape that is adapted to clean the user's gums and/or gum line. For example, the ribs 218 may be angled with respect to the gums so as to clean the space between the gums and the teeth. In some examples, the ribs 218 are configured to contact the gums at an angle between 30 and 60 degrees, between 40 and 50 degrees, or approximately 45 degrees, as discussed below with reference to the fingers 226 of the ridges.
In the illustrated embodiment, the oral hygiene device 200 includes ribs 218 positioned within the channel 216. The ribs 218 positioned within the channel 216 can be configured to clean the upper teeth of the user. As illustrated, ribs 218 extend generally across the channel 216 from the inner wall 220 to the outer wall 222, as well as along the inner surfaces of the inner wall 220 and the outer wall 222. Such a configuration can allow the ribs to contact multiple surfaces of the user's teeth simultaneously as described above.
In the illustrated embodiment, the oral hygiene device 200 includes about 33 ribs in the channel 216, although other numbers are possible (e.g., about 15, about 20, about 25, about 30, about 35, about 40, about 45, or about 50 ribs 218). The ribs 218 may be spaced evenly or unevenly. In some embodiments, the ribs 218 are spaced apart so as to be aligned with the spaces between the user's teeth or the interproximal contact area (IPC) when the oral hygiene device 200 is inserted into the mouth. In some embodiments, there can be more ribs 218 disposed in the channel 216 than there are upper teeth. This can provide additional coverage for teeth cleaning and can reduce the amount a user would need to move the oral hygiene device 200 in order to contact and adequately clean all the teeth. In some embodiments, the ribs 218 are spaced about 2 mm, 4 mm, 6 mm, 8 mm, or 10 mm apart, although other spacings are possible. The position and spacing of the ribs 218 can be selected to facilitate operation of the device. For example, the ribs 218 can be positioned so as to efficiently clean the teeth. In some embodiments, the oral hygiene device 200 can have different sizes to accommodate different mouth sizes. For example, in some embodiments, the oral hygiene device 200 can be adapted for use in a child's mouth. In this case, the oral hygiene device 200 can include fewer ribs 218 and/or different rib spacing, based on a child's mouth's dimensions and/or number of teeth. In some embodiments, the oral hygiene device 200 can be adapted for use in an adult's mouth. In some embodiments, the spacing of the ribs 218 is a function of the average dimensions of each tooth.
In some embodiments, the shape of the individual ribs 218 may be varied to suit the particular teeth the ribs will contact during use. For example, as illustrated, the ribs 218 positioned within the back parts of the channel 216 (i.e., the ribs configured to clean molars) can have a wider cutout shape configured to match the thickness of the molars, and the ribs 218 positioned within the front part of the channel 216 (i.e., the ribs configured to contact incisors) have a narrower cutout shape configured to match the thickness of the incisors). In some embodiments, the shape of the ribs 218 positioned within the channel 216 is configured to contact the front surface, bottom surface, and back surface of the user's upper teeth
As shown in
The ribs 218 positioned within the channel 216 may be connected by a spline 229 as shown. The spline 229 can be configured to clean the occlusal surface of the teeth. The spline 229 can be positioned within the channel 216 on the bottom wall 224. In some embodiments, the spline 229 runs continuously from one end of the channel 216 to the other. The shape, size, materials, and placement of the spline 229 can be based on specific desirable characteristics, such as the ability to clean the occlusal surface of each tooth. In some embodiments, the spline 229 is broken at various points along its length to comprise various discrete sections. For example, as best seen in
Opposite the channel 216, the oral hygiene device 200 also includes ribs 218 extending outwardly (e.g., downwardly) from the bottom wall 224. These ribs 218 can be configured to clean the user's bottom teeth. As illustrated, the ribs 218 extend generally across the bottom wall 224 form the inner wall 220 to the outer wall 222, although this need not be the case in all embodiments. In the illustrated embodiment, the oral hygiene device 200 includes 16 ribs extending from the bottom wall 224 opposite the channel 216, although other numbers are possible (e.g., about 10, about 20, about 25, about 30). As with the ribs 218 positioned within the channel 216, the ribs 218 positioned opposite the channel 216 may be spaced evenly or unevenly. The spacing or number of the ribs 218 positioned within the channel 216 need not match the spacing or number of the lower ribs 218 positioned opposite the channel 216. In some embodiments, the spacing of the lower ribs 218 is greater than the spacing of the upper ribs 218 (for example, as shown). In some embodiments, the number of lower ribs 218 is less than the number of upper ribs 218. In some embodiments, the ribs 218 positioned opposite the channel are about 2 mm, 4 mm, 6 mm, 8 mm, 10 mm, 12 mm, 14 mm, 16 mm, 18 mm, or 20 mm apart, although other spacings are possible.
As noted previously, the shape of the individual ribs 218 may be varied to suit the particular teeth the ribs 218 will generally overlie during use. This may also be true for the lower ribs 218. For example, the ribs 218 positioned within the back parts of device 200 (i.e., the ribs configured to overlie the lower molars) can include a wider cutout shape configured to match the thickness of the molars, and the ribs 218 positioned on the front part of the device 200 (i.e., the ribs configured to overlie the front incisors) can include a narrower cutout shape configured to match the thickness of the incisors). In some embodiments, the shape of the lower ribs 218 extending from the bottom wall 224 are configured to contact the front surface, top surface, and back surface of the user's lower teeth.

In other embodiments, various containers can be provided that are configured to enclose oral hygiene devices in their closed or U-shaped configurations.
As mentioned previously, in some embodiments, the oral hygiene devices described herein are configured to be portable and/or disposable. Those of ordinary skill in the art, upon consideration of this disclosure, will appreciate that the size, shape, and type of container selected to facilitate carrying the oral hygiene device in a space efficient manner suitable for a pocket or bag.
In the illustrated embodiment, five beads 640 of mouthwash, breath freshener, toothpaste, desensitizing paste or gel, or whitening paste or gel are shown, but other numbers of beads 640, as well as other positions for the beads 640, are possible. In some embodiments, the beads 640 comprise are referred to as “dabs.” As mentioned previously, in some embodiments, the oral hygiene devices described herein are configured to be useable without water or toothpaste, as such the beads 640 of mouthwash, breath freshener, toothpaste, desensitizing paste or gel, or whitening paste or gel can be configured to also be useable without requiring water and/or without requiring the user to rinse out his or her mouth after use. Alternatively, in some embodiments, the beads 640 can comprise beads of a dentifrice that can be used with water during use of the device. The size, shape, materials, and location of the beads is selected for specific characteristics including the ability to freshen breath or clean the mouth.
In some embodiments, the beads 640 are positioned within pockets or indentations formed on the device 600. For example, as best seen in
In the illustrated embodiment of
In some embodiments, the beads 640 of mouthwash, breath freshener, toothpaste, desensitizing paste or gel, or whitening paste or gel are positioned on the oral hygiene device so as to be automatically activated when the oral hygiene device is used by the user. In some embodiments, the beads 640 are activated by biting, grinding, or crushing by the user's teeth during use of the oral hygiene device 600. In some embodiments, the beads 640 dissolve into the mouth during use.
In some embodiments, the beads or dabs 640 can comprise a formulation configured to clean and freshen one's mouth, and that can be used without water. In some embodiments, the beads or dabs 640 comprise a formulation that is safe to be swallowed. This can allow a user to quickly and easily use the oral hygiene devices anywhere. In other embodiments, the beads or dabs 640 can comprise formulations that are not safe to be swallowed (such as formulations that include fluoride or mouthwash). Several example formulations are shown in the following tables.
While any of the above-listed sample formulations are useable in the beads or dabs 640, testing has revealed that sample formulation 8 and sample formulation 9, which include menthol as a flavorant at 0.50% w/w and 0.75% w/w, respectively, are potent, and can provide a strong burst of freshener, which can be desirable.
Although the beads 640 are depicted in the oral hygiene device 600, a person of skill in the art, guided by this disclosure, would understand that the beads 640 can be incorporated into any of the various embodiments of the oral hygiene device described herein. For example, the oral hygiene device 700 of
With reference to

An additional feature that can facilitate good fit for the device 700 is visible in
The body 702 may be made of a rigid, semi-rigid, or flexible material, such as plastic, rubber, a polymer, or other suitable material. In some embodiments, the body 702 is rigid enough to provide general support and shape for the oral hygiene device 700, while remaining flexible enough to allow the body 702 to fit to the particular anatomy of the user's mouth and teeth. In some embodiments, the body 702 comprises a thermoplastic elastomer (TPE), high-density polyethylene (HDPE), polypropylene (PP), low-density polyethylene (LDPE), polyamides, polyolefin or other resins, polychloro-trifluoroethylene, various thermoplastics, and/or various elastomers. In some embodiments, the body 702 may comprise a food grade polypropylene. The composition of the body 702 is not limited to the above materials, but is selected for specific characteristics including enough rigidity to provide general support and shape for the oral hygiene device 700, while including enough flexibility to allow the body 202 to fit to the particular anatomy of the user's mouth and teeth.
The body 702 may be formed such that the walls (e.g., the inner wall 720, the outer wall 722, and the bottom wall 724) are sufficiently thin so as to allow the body 702 to flex and conform to the shape of the user's mouth. For example, in some embodiments, the walls of the body 202 are about 2 mm, 1.5 mm, 1.0 mm, 0.75 mm, 0.5, or 0.25 mm thick. In some embodiments, the nominal thickness of the walls of the body 702 is about 1.2 mm. These thicknesses are provided by way of example, and the thickness of the walls of the body 702 can be selected to provide the desired characteristics described throughout this application.
In some embodiments, the oral hygiene device 700 can be provided in a variety of sizes (e.g., small, medium, large, adult, or child) configured for use by users that have different size mouths. In some embodiments, the oral hygiene device 700 can be provided in a size that is generally configured to fit most mouth sizes. For example, in some embodiments, the device 700 may comprise a width configured to fit mouths with a molar to molar width of about 50 mm to 65 mm, about 50 mm to 62 mm, about 52 mm to 58 mm, or about 54 mm to 56 mm. The device 700 may comprise a length configured to fit mouths with a front tooth to rear molar length of between 40 mm and 55 mm, between 40 and 50 mm, or between 43 and 49 mm. In some embodiments, the width of the device 700 is at least 62 mm. Measurements of many mouths were taken between the buccal of the second molar on the right and the buccal of the second molar of the left of the upper teeth. 62 mm was determined to be widest measurement.
As illustrated, the oral hygiene device 700 includes a handle 710. The handle 710 can be configured as a tab, although other shapes are possible as described in greater detail below (see, for example,
Similar to the oral hygiene devices 100a, 100b, 200 (and others) described generally above, the oral hygiene device 700 can include teeth cleaning features configured to clean the user's teeth when the device is used. In the illustrated embodiment, the teeth cleaning features comprise the ribs 718, although in other embodiments, other types of teeth cleaning features (e.g., foam, bristles, textured surfaces, etc.) can be used in addition to or in place of the ribs 718.
The ribs 718 can be formed of the same material as the body 702, or the ribs 718 can be formed of a softer or more flexible material than the body 702 as described above. Advantageously, forming the body 702 and the ribs 718 of different materials may improve functionality, comfort, and efficiency of the device. For example, as described above the body 702 can be formed of a generally stiffer and more rigid material to provide structural support for the device 700, while the ribs 718 can be formed of a generally less rigid or softer material. The softer material of the ribs 718 can provide more user comfort during use, while also better conforming to the user's mouth and teeth shape to provide increased cleaning efficiency.
The ribs 718 can be integrally formed with the body 702 or can be separately formed and attached to the body 702. In some embodiments, the body 702 and ribs 718 are co-molded in a two-step molding process, such as a double shot or overmolding process, as described above. In other embodiments, the body 702 and the ribs 718 can be formed separately and then attached to one another. In some embodiments, the ribs 718 comprise a thermoplastic elastomer (TPE), silicon rubber, high-density polyethylene (HDPE), polypropylene (PP), low-density polyethylene (LDPE), polyamides, polychlorotrifluoroethylene, various thermoplastics, and/or various elastomers. In some embodiments, the ribs 718 comprise a food grade TPE or thermoplastic polyurethane (TPU). The composition of the ribs 718 is not limited to the above materials, but can be selected for specific characteristics including the ability to clean on and around teeth. In some embodiments, the ribs 718 may comprise a material with a Shore A hardness of between 70 and 100, between 75 and 95, or between 80 and 90, or between 85 and 90. Shore A hardnesses within these ranges can provide the comfort and efficiency advantages discussed above.
In the illustrated embodiment, the ribs 718 are positioned within the channel 716. In some embodiments, the shape of the ribs 718 can be formed in order to contour to a user's mouth and teeth. In some embodiments, the ribs 718 are about 1.2 mm, 1.0 mm, 0.8 mm, 0.6 mm, or 0.5 mm thick, although other thicknesses, both thinner and thicker than these example values are possible. The thickness can be selected to facilitate teeth cleaning efficiency and/or user comfort.
In some embodiments, the size and shape of the ribs 718 varies depending upon the location of the ribs 718 on the body 702. For example, the size and shape of the ribs 718 can be adjusted to suit the general size and shape of the particular teeth the ribs 718 will generally overlie when the oral hygiene device 700 is positioned within the mouth. Ribs 718 that are positioned on the body 702 to generally overlie molars (which are generally wider) may have a different shape than ribs 718 that are positioned to overlie incisors (which are generally thinner). The ribs 718 can also be configured such that they contact more than one surface of the user's teeth at a time. For example, the ribs 718 can be configured to contact the front, bottom and back surfaces of the user's upper teeth and/or the front, top, and back surfaces of the user's teeth simultaneously.
These features can be seen, for example, in the cross-sectional views of
The ribs 718 may also have a shape that is adapted to clean the user's teeth, gums, and/or gum line. In the illustrated embodiment, the oral hygiene device 700 includes ribs 718 positioned within the channel 716. The ribs 718 positioned within the channel 716 can be configured to clean the upper and/or lower teeth of the user depending upon the orientation of the device 700. As illustrated, ribs 718 extend generally across the channel 716 from the inner wall 720 to the outer wall 722, as well as along the inner surfaces of the inner wall 720 and the outer wall 722. Such a configuration can allow the ribs to contact multiple surfaces of the user's teeth simultaneously as described above. In some embodiments, the shape of the individual ribs 718 may be varied to suit the particular teeth the ribs will contact during use. For example, as illustrated, the ribs 718 positioned within the back parts of the channel 716 (i.e., the ribs configured to clean molars) can have a wider cutout shape configured to match the thickness of the molars, and the ribs 718 positioned within the front part of the channel 716 (i.e., the ribs configured to contact incisors) have a narrower cutout shape configured to match the thickness of the incisors).
The one or more of the ribs 718 can include fingers 726 extending therefrom. The fingers 726 may be angled with respect to the gums so as to clean the space between the gums and the teeth. The fingers 726 be configured as protrusions or extensions that extend from the ribs 718. In some embodiments, the fingers 726 can be configured to clean the gum line. In some embodiments, the fingers 726 can be angled inwardly at an angle of between 30 and 60 degrees, between 40 and 50 degrees, or approximately 45 degrees with respect to the bottom wall 724, although other angles are also possible. The angle of the fingers 726 can be set in order to provide an optimal cleaning angle when the finger 726 contacts the teeth and/or the gum line (for example, as discussed above with regards to the Bass technique).
In some embodiments, the ribs 718 can be smaller or omitted at the rear ends of the oral hygiene device 700. For example, as shown in
Moreover, in some embodiments, the rear most portions of the device 700 can be made from the same material as the ribs 718. Thus, the rearmost portions can be softer than body 702. For example, comparing
In the illustrated embodiment, the oral hygiene device 700 includes about 35 ribs in the channel 716, although other numbers are possible (e.g., about 15, about 20, about 25, about 30, about 35, about 40, about 45, or about 50 ribs 718). The ribs 718 may be spaced evenly or unevenly. In some embodiments, the ribs 718 are spaced apart so as to be aligned with the spaces between the user's teeth or the interproximal contact area (IPC) when the oral hygiene device 700 is inserted into the mouth. In some embodiments, there can be more ribs 718 disposed in the channel 716 than there are upper teeth. This can provide additional coverage for teeth cleaning and can reduce the amount a user would need to move the oral hygiene device 700 in order to contact and adequately clean all the teeth. In some embodiments, the ribs 718 are spaced about 2 mm, 4 mm, 6 mm, 8 mm, or 10 mm apart, although other spacings are possible. The position and spacing of the ribs 718 can be selected to facilitate operation of the device. For example, the ribs 718 can be positioned so as to efficiently clean the teeth. In some embodiments, the spacing of the ribs 718 is a function of the average dimensions of each tooth.
The ribs 718 positioned within the channel 716 may be connected by a spline 729 as shown, for example, in
The oral hygiene device 700 may also include reservoirs 730 for holding beads or dabs of a cleaning or freshening material as described above. In the illustrated embodiment, the device 700 includes three reservoirs 730 that extend through the apertures 715 of the body 702. As shown, one reservoir 730 is positioned at the front of the device 700 and the remaining two reservoirs 730 are positioned toward the rear of the device 700. These positions for the reservoirs 730 may work well to release the material of the dabs or beads over the much or all of the user's mouth or teeth and provide good coverage. Other numbers of reservoirs 730 and other positions for the reservoirs 730 are also possible. The reservoirs 730 can be formed from the same material as the spline 729 and the ribs 718. As shown in the figures, in some embodiments, the reservoirs 730 extend above and below the bottom wall 724. This may facilitate release of the bead or dab material. For example, in some embodiments, the reservoirs 730 may extend at least 0.5 mm, at least 1.0 mm, or at least 1.5 mm above and/or below the body 702.
As illustrated, in some embodiments, the reservoirs 730 can include within them one or more openings that extend therethrough. The openings may facilitate release of the bead or dab material both above and below the device 700 during use. In the illustrated embodiment, the front reservoir 730 includes six openings, while the rear two reservoirs 730 can include five openings. The size and number of the openings through the reservoirs 730 can be configured to release of the bead or dab material.
As shown in
The oral hygiene device 700 can be configured to be used to clean and/or freshen a user's mouth, teeth, and tongue. An example method of use for the device 700 will now be described. In this example, the device 700 can be inserted into the user's mouth. The user may hold the device 700 using the handle 710. The device 700 can be inserted into the mouth such that the user upper or the user's lower teeth are positioned within the channel 716. For example, the user's upper teeth can be positioned within the channel 716. With the device 700 so positioned, the user may manipulate the device 700 to freshen the mouth. For example, the user may manipulate the device 700 by moving the device 700 side-to-side and back-and-forth. During this motion, the ribs 718 can contact and clean the surfaces of the user's teeth. At the same time the fingers 726 can contact and clean the user's gum line. The motion can produce similar effects as the Bass technique described above. Further, while using the device, the dab and bead material device can be naturally released, providing additional cleaning and/or freshening for the mouth.
In some embodiments, while cleaning the user's upper teeth, the teeth cleaning features (ridges 732) of the bottom wall 724 of the device 700 can clean the user's tongue. This can be accomplished by moving the ridges 732 across the surface of the user's tongue. Advantageously, the bead or dab material can be released from the reservoir 730 onto the user's tongue providing additional freshening.
After the user's upper teeth and tongue are cleaned, the user can flip the device 700, such that the user's lower teeth are received within the groove 716. The device can then be used in a similar manner to clean the user's lower teeth. In some embodiments, the user's lower teeth can be cleaned first, before cleaning the user's upper teeth.
The body 802 can be made of a flexible material, or otherwise configured to bend or flex, so that the user can form the formable oral hygiene device 800 into a U-shape when inserting the device 800 into the user's mouth. The U-shape will conform the formable oral hygiene device 800 to the general shape of the user's mouth and teeth. The user may then use the formable oral hygiene device 800 in the manner previously described.
The oral hygiene device described herein can be used to clean teeth and/or freshen the mouth as described above. In some embodiments, the devices can be used as a supplement to a traditional tooth care routine, which generally involves twice daily brushing. For example, the devices can be used on-the-go, in between brushings, as a supplement to improve oral healthcare. In some embodiments, this is facilitated by the fact that the devices can be configured to be useable without requiring access to water and/or a bathroom. In addition, by reducing or eliminating the need for people to find public restrooms while on-the-go to clean their teeth, people can avoid the unsanitary conditions associated with public restrooms (such as the spread of germs and other unsanitary material due to toilet plume).
In some embodiments, the devices can be configured to provide fluoride as means to prevent tooth decay. The Global Burden of Disease Study from 2016 estimated that oral diseases affected half of the world's population (3.58 billion people) with dental caries (tooth decay) in permanent teeth being the most prevalent condition assessed. Poor oral hygiene and inadequate exposure to fluoride can have negative effects on oral health. Further, oral health is a key indicator of overall health, wellbeing and quality of life. The World Health Organization (WHO) defines oral health as “a state of being free from chronic mouth and facial pain, oral and throat cancer, oral infection and sores, periodontal (gum) disease, tooth decay, tooth loss, and other diseases and disorders that limit an individual's capacity in biting, chewing, smiling, speaking, and psychosocial wellbeing.”
Additionally, poor oral health can be even more common in developing countries, with increasing urbanization and changes in living conditions. The prevalence of oral diseases continues to increase notably due to inadequate exposure to fluoride and poor access to primary oral health care services. Heavy marketing of sugars, tobacco and alcohol also leads to growing consumption of unhealthy products.
Dental caries results when microbial biofilm (plaque) formed on the tooth surface converts the free sugars contained in foods and drinks into acids that dissolve tooth enamel and dentine over time. With continued high intake of free sugars, inadequate exposure to fluoride and without regular microbial biofilm removal, tooth structures are destroyed, resulting in development of cavities and pain, impacts on oral-health-related quality of life, and, in the advanced stage, tooth loss and systemic infection.
The burden of oral diseases and other non-communicable diseases (NCDs) can be reduced through public health interventions by addressing common risk factors. In addition, to the NCDs' common risk factors, inadequate exposure to fluoride and a number of social determinants of health should be addressed to prevent oral diseases and reduce oral health inequalities.
Dental caries can be largely prevented by maintaining a constant low level of fluoride in the oral cavity. Optimal fluoride can be obtained from different sources such as fluoridated drinking water, salt, milk and toothpaste. Twice-daily tooth brushing with fluoride-containing toothpaste (1000 to 1500 ppm) should be encouraged, although people often fail to use adequate fluoride. Long-term exposure to an optimal level of fluoride results in substantially lower incidence and prevalence of tooth decay across all ages. Accordingly, the devices described herein can be used as a supplement for applying fluoride. This is even more true for developing areas where access to water is not available.
In some embodiments, the devices can be configured to provide a dose of fluoride of approximately 1000-1500 ppm. This dose of fluoride can be included in the device, but would have to be spit out and cannot be swallowed. It may be in the dabs or beads or dispensed in another mode, such as paste coated within the channel of the device. This can greatly improve dental health in areas where access to water is limited. This may be especially helpful for children (especially since an estimated 486 million children suffer from tooth decay).
The oral hygiene devices of the present application may also be especially useful for people with limited mobility. For example, because the device is configured to clean substantially all the teeth at once, they may require less dexterity than a traditional toothbrush. Further, the devices can be used by caretakers who are cleaning the teeth of another person, such as a person in a nursing home. Use of the device can be particularly advantageous because caretaker can use the device without having to place their fingers into the person's mouth. This can reduce the time required to clean the persons teeth and freshen the mouth and clean the tongue leading to better health outcomes for the residents and better social interactions.
As best shown in
In some embodiments, the cutout 1821 extends at least, at most, or about 10%, 20%, 25%, 30%, 33%, 40%, 50%, or 60% of the length of the back wall, measured from the rear most portion of the device 1800 towards the front most portion of the device.
In some embodiments, the device 1800 may comprise one or more materials having a durometer of 60 Shore A, 75 Shore A, and 90 Shore A. These durometers can refer to the material that comprises the body and/or the ribs of the device 1800. Other durometers may also be used as described above.
Additionally, in some embodiments, the surface finish of the device 1800 (e.g., the surface finish of the ribs or other portions of the device that contact the teeth during use) can be configured to have a degree of roughness. The roughness may further facilitate cleaning, such as removal of plaque. In some embodiments, the surface finish comprises an EDM (electrical discharge machining) surface finish. The surface finish may comprise, for example, a VDI surface finish of 30 (123 microinches). Other surface finishes can also be used.
Although not illustrated in
In some embodiments, one or more of the ribs can include a tapered portion. The tapered portion can be positioned on the distal ends or inner surfaces or edges of the ribs. The tapered portion can be configured to fit in between teeth. In some embodiments, some of the ribs included a fanned portion while some of the ribs include a tapered portion.
In some embodiments, a portion of the outer rear ribs may flare outwardly or include a concave shape configured to follow the contours of the teeth's surface. In an embodiment, the last third of the outside ribs can include the flare or concave shape.
Testing was conducted on the device of
Post-brush plaque values according to Modified Navy Plaque Index (Lang et al. 2011) for teeth 48, 47, 46, 45 and 44 (molars and premolars) were recoded into variables of cleaning efficacy percentages:
In this exploratory statistical analysis means, standard deviations, medians, inter-quartile ranges (lower and upper limits) and number of valid cases are reported for the 12 variables of tooth surfaces buccal′, lingual′, mesial′, distal′, buccal risk fields ABCDF′, lingual risk fields ABCDF′, total′, K—buccally′, L—lingually′, KL—mesially′, MN—distally′ and KL-KLMN—total′ for the exploration toothbrush with 3 runs/test cycles.
Furthermore a boxplot and an error bar diagram are used to depict the distribution of plaque removal values for the exploration device.
Analysis of single teeth resp. documentation of plaque removal values of single teeth per single toothbrush is performed.
Applied statistical software package: IBM SPSS Statistics Premium, release 25, 64-bit-version.
The results are present in ) (outside the 3*interquartile range).
Additional results are summarized in
The device was tested at four incisors, canines, two premolars and three molars in anatomic position with clinically validated organic plaque simulation (PG-Plaque simulating young 12 h regrowth plaque). The lateral-rotating manual movement of the device within 60 s brushing was limited to 8 mm, therefore, the wisdom teeth did not have device contact.
The plaque control results were documented as plaque removal percentage in medians (
The mean plaque removal at buccal surfaces was 30.48%, at lingual smooth surfaces 22.75%, and in-between the teeth mesially 13.02% and distally 11.79%. The risk fields next to the gum line were cleaned by less than 10% (3.93% buccally, 7.58% lingually).
The occlusal risk fields were assessed according to the Occlusal Planimetrical Plaque Index oPPI (Lang et al. 2011) and all fields of all premolars and molars exhibited less than 49% plaque removal (Code 2).
These results demonstrate that the potential of plaque control of the device is rather high and, therefore, ORMED is offering a joint project of optimization of lamellae arrangement, saliva secretion stimulation and caries prevention.
While the above detailed description has shown, described, and pointed out novel features of the development as applied to various embodiments, it will be understood that various omissions, substitutions, and changes in the form and details of the device or process illustrated may be made by those skilled in the art without departing from the spirit of the development. As will be recognized, the present development may be embodied within a form that does not provide all of the features and benefits set forth herein, as some features may be used or practiced separately from others. All changes which come within the meaning and range of equivalency of the claims are to be embraced within their scope.
The foregoing description details certain embodiments of the systems, devices, and methods disclosed herein. It will be appreciated, however, that no matter how detailed the foregoing appears in text, the systems, devices, and methods may be practiced in many ways. As is also stated above, it should be noted that the use of particular terminology when describing certain features or aspects of the invention should not be taken to imply that the terminology is being re-defined herein to be restricted to including any specific characteristics of the features or aspects of the technology with which that terminology is associated.
It will be appreciated by those skilled in the art that various modifications and changes may be made without departing from the scope of the described technology. Such modifications and changes are intended to fall within the scope of the embodiments. It will also be appreciated by those of skill in the art that parts included in one embodiment are interchangeable with other embodiments; one or more parts from a depicted embodiment may be included with other depicted embodiments in any combination. For example, any of the various components described herein and/or depicted in the Figures may be combined, interchanged or excluded from other embodiments.
With respect to the use of substantially any plural and/or singular terms herein, those having skill in the art may translate from the plural to the singular and/or from the singular to the plural as is appropriate to the context and/or application. The various singular/plural permutations may be expressly set forth herein for sake of clarity.
It will be understood by those within the art that, in general, terms used herein are generally intended as “open” terms (e.g., the term “including” should be interpreted as “including but not limited to,” the term “having” should be interpreted as “having at least,” the term “includes” should be interpreted as “includes but is not limited to,” etc.). It will be further understood by those within the art that if a specific number of an introduced claim recitation is intended, such an intent will be explicitly recited in the claim, and in the absence of such recitation no such intent is present. For example, as an aid to understanding, the following appended claims may contain usage of the introductory phrases “at least one” and “one or more” to introduce claim recitations. However, the use of such phrases should not be construed to imply that the introduction of a claim recitation by the indefinite articles “a” or “an” limits any particular claim containing such introduced claim recitation to embodiments containing only one such recitation, even when the same claim includes the introductory phrases “one or more” or “at least one” and indefinite articles such as “a” or “an” (e.g., “a” and/or “an” should typically be interpreted to mean “at least one” or “one or more”); the same holds true for the use of definite articles used to introduce claim recitations. In addition, even if a specific number of an introduced claim recitation is explicitly recited, those skilled in the art will recognize that such recitation should typically be interpreted to mean at least the recited number (e.g., the bare recitation of “two recitations,” without other modifiers, typically means at least two recitations, or two or more recitations). Furthermore, in those instances where a convention analogous to “at least one of A, B, and C, etc.” is used, in general such a construction is intended in the sense one having skill in the art would understand the convention (e.g., “a system having at least one of A, B, and C” would include but not be limited to systems that have A alone, B alone, C alone, A and B together, A and C together, B and C together, and/or A, B, and C together, etc.). In those instances where a convention analogous to “at least one of A, B, or C, etc.” is used, in general such a construction is intended in the sense one having skill in the art would understand the convention (e.g., “a system having at least one of A, B, or C” would include but not be limited to systems that have A alone, B alone, C alone, A and B together, A and C together, B and C together, and/or A, B, and C together, etc.). It will be further understood by those within the art that virtually any disjunctive word and/or phrase presenting two or more alternative terms, whether in the description, claims, or drawings, should be understood to contemplate the possibilities of including one of the terms, either of the terms, or both terms. For example, the phrase “A or B” will be understood to include the possibilities of “A” or “B” or “A and B.”
All references cited herein are incorporated herein by reference in their entirety. To the extent publications and patents or patent applications incorporated by reference contradict the disclosure contained in the specification, the specification is intended to supersede and/or take precedence over any such contradictory material.
The term “comprising” as used herein is synonymous with “including,” “containing,” or “characterized by,” and is inclusive or open-ended and does not exclude additional, unrecited elements or method steps.
All numbers expressing quantities of ingredients, reaction conditions, and so forth used in the specification and claims are to be understood as being modified in all instances by the term “about.” Accordingly, unless indicated to the contrary, the numerical parameters set forth in the specification and attached claims are approximations that may vary depending upon the desired properties sought to be obtained by the present invention. At the very least, and not as an attempt to limit the application of the doctrine of equivalents to the scope of the claims, each numerical parameter should be construed in light of the number of significant digits and ordinary rounding approaches.
The above description discloses several methods and materials of the present development. This development is susceptible to modifications in the methods and materials, as well as alterations in the fabrication methods and equipment. Such modifications will become apparent to those skilled in the art from a consideration of this disclosure or practice of the development disclosed herein. Consequently, it is not intended that this development be limited to the specific embodiments disclosed herein, but that it cover all modifications and alternatives coming within the true scope and spirit of the development.
