The present invention relates to a tool for seating an orthodontic aligner. In some aspects, the present invention relates to a tool for seating and unseating an orthodontic aligner. Moreover, in some aspects, the present invention relates to a tool that fits within a case for an orthodontic aligner.
In order for orthodontic patients to optimize teeth movement, experts recommend seating orthodontic aligners by chewing on something that is firm. Existing options for seating aligners include aspects that can be undesirable. For example, existing devices can be bulky, uncomfortable, too large to fit in an orthodontic aligner case, less durable than desired, have a less than desirable life span, or have an undesirably high cost.
After an orthodontic aligner is seated on a patient, the patient needs a way to remove the orthodontic aligner. Because orthodontic aligners can be difficult to remove without a tool, it can be desirable to use a tool to facilitate unseating and removing the orthodontic aligner. Existing tools used for this purpose are separate devices from the devices used to seat an orthodontic aligner. Accordingly, existing tools for seating and removing orthodontic aligners require a patient to purchase, keep track of, store, or clean multiple devices, which can be undesirable.

The reinforcing portion 0148 is positioned in a narrower portion 0150 of the handle portion 0104 that is adjacent to the hook 0124. As can be seen, a narrower portion 0150 of the handle portion 0104 can be created when the hook 0124 is formed by a recess 0128 in the handle portion 0104. Accordingly, the narrower portion 0150 of the handle portion 0104 has a smaller width than other portions along the length of the handle portion 0104 and could be weaker than other portions without reinforcement. The reinforcing portion 0148 is configured to strengthen the narrower portion 0150 of the handle portion 0104 that is adjacent to the hook 0124. In some embodiments, the reinforcing portion 0148 has a mass equal to approximately 10% to 50% of the mass of the second material 0140 in the hook 0124.
With reference to the cross section of the tool shown in
In some embodiments, the first material 0138 makes up 50 to 80 wt. % of the tool 0100. The first material 0138 can make up 70 to 100 wt. % of the seating portion 0102. The first material 0138 can have a Shore A hardness equal to 40 to 90, optionally about 75, as measured according to ISO 868:2003. In some embodiments, the first material 0138 can have a Shore D hardness equal to 10 to 40, optionally about 25, as measured according to ISO 868:2003.
In some embodiments, thermoplastic elastomer (e.g., thermoplastic polyurethane), polypropylene, or a combination thereof make up 80 to 100 wt. % of the tool 0100.
With reference now to
A second step occurs subsequent to the first step and comprises positioning the seating portion 0102 of the tool 0100 between an upper set 0154 of teeth and a lower set 0156 of teeth.

With reference again to
A second step occurs subsequent to the first step and comprises using the hook 0124 to contact, catch, and apply force to a contacted portion of the aligner 0158, thereby unseating the aligner 0158 to facilitate removal of the aligner 0158. In some embodiments, the contacted portion of the aligner 0158 is an edge 0174 of the aligner 0158.
Turning to
The seating portion 1402 can include a first rippled structure 1430 and a second rippled structure 1432. For example, the rippled structures 1430,1432 can have the shape of a series of waves having a semi-parabolic shape extending away from the handle portion 1404. The series of waves comprises a plurality of troughs 1414 and a plurality of peaks 1416, which can alternate. Each wave can be, but is not required to be, complete. The shape of the series of waves can be sinusoidal.
The seating portion 1402 is positioned at the front 1408 of the tool 1400, which is defined by reference to the seating portion 1402. The handle portion 1404 is positioned at the rear 1410 of the tool 1400. Having defined the front 1408 and the rear 1410 of the tool 1400, it is useful to define the top 1462 of the tool 1400 with reference to the front-most peak 1412 of the series of waves. In particular, the top 1462 of the tool 1400 is defined so that the front-most peak 1412 of the series of waves is positioned at the top 1462 of the tool 1400. The bottom 1464 of the tool 1400 is positioned opposite the top 1462 of the tool 1400. Meanwhile, the right side 1430 of the tool 1400 is defined as the side of the tool 1400 that is to the right of the tool 1400 from the perspective of an upwardly oriented viewer who is looking at the tool 1400 while (i) the front 1408 of the tool 1400 is facing the viewer, and (ii) the tool 1400 is positioned with the top 1462 side directed vertically up.

The handle portion 0104 can comprise a body 1466 and protrusions 1422 that protrude from the body 1466. The protrusions 1422 can be configured to reduce slipping between a hand and the handle portion 1404 when the handle portion 1404 is in use. The protrusions 1422 are spaced from each other. In some embodiments, the protrusions 1422 are rounded. The protrusions 1422 can be hemispherical.
The tool 1400 is small enough to fit in an orthodontic case. Having a properly sized tool can be useful for other purposes as well. For example, it can be useful if the tool is small enough to fit in an orthodontic case, to be grasped by a typical human hand, to fit between typical sets of human teeth, to seat an orthodontic aligner, to unseat an orthodontic aligner or a combination thereof. Meanwhile, it can be useful if the tool is large enough to accomplish various functions, for example, to be grasped by a typical human hand, to seat an orthodontic aligner, to unseat an orthodontic aligner, or a combination thereof.
For example, the tool 1400 can be approximately 55-60 mm long as measured from the front 1408 to the rear 1410 of the tool 1400. The tool can be approximately 48-55 mm wide as measured in a direction from the right side 1430 to the left side 1432 of the tool 1400. The tool can be approximately 3-5 mm thick as measured in a direction perpendicular to the direction in which the length of the tool 1400 is measured, perpendicular to the direction in which the width of the tool 1400 is measured, and measured from the highest part of the top 1462 of the tool 1400 to the lowest part of the bottom 1430 of the tool 1400. In some embodiments, any dimension of the tool (length, width, thickness, or a combination thereof) can vary by 25, 20, 15, 10, 5, 4, 3, 2, or 1% from the listed dimensions of the illustrative embodiment.
Like tool 0100 described in

The second material 1440 can be configured to be me more rigid than the first material 1438. In some embodiments, the protrusions 0122 from the handle portion 0104 can comprise, consist essentially of, or consist of the second material 0140.
In some embodiment, the first material 1438 and the second material 1440 make up 80 to 100 wt. %, optionally 90 to 100 wt. %, of the tool 1400.
In some embodiments, the first material 1438 can be a first polymer, a first rubber, a first plastic, thermoplastic elastomer (TPE) (e.g., thermoplastic polyurethane (TPU)), or a combination thereof. The second material 1440 can be a second polymer, a second rubber, a second plastic, polypropylene (PP), or a combination thereof.
In some embodiments, the second material 1440 is configured to have a Shore D hardness equal to 70 to 83, optionally about 77, where the Shore D hardness is measured according to ISO 868:2003.
In some embodiments, the second material 1440 makes up 20 to 50 wt. % of the tool 1400. In some embodiments, the second material 0140 makes up 50 to 90 wt. % of the handle portion 1404.

Although the invention has been described above and in the drawings using a handle portion 0104 that is generally the shape of a rectangular prism with rounded edges, the tool 0100 is not limited to this shape. For example, the edges need not be rounded, although rounded edges can be more comfortable to a user. Additionally, the handle need not be generally shaped like a rectangular prism, although the rectangular prism shape can facilitate a user's ability to control the movement of the seating portion 0102 and can help provide a thin tool 0100 that fits more easily in a case for an orthodontic aligner 0158.
Although the invention is described above and in the drawings using a seating portion 0102 that is generally a smoothly rippled shape comprising a series of identical or nearly identical sinusoidal waves with rounded edges, the tool 0100 is not limited to this shape. For example, the edges need not be rounded, although rounded edges can be more comfortable to a user. Additionally, the waves can vary in their shape and orientation, although it can be advantageous for the adjusted amplitude of the waves to vary by no more than 30, 20, 15, 10, 5, 4, 3, 2 or 1% from the shortest adjusted amplitude wave to the largest adjusted amplitude wave, where the amplitude is measured as the distance between adjacent opposite facing peaks 0116 where one peak 0116 is on the top 0162 of the tool 0100 and one peak 0116 is on the bottom 0164 of the tool 0100. Avoiding variations in the adjusted amplitude of the wave peaks 0116 can facilitate a user's ability to seat an aligner 0158 and can help provide a thin tool 0100 that fits more easily in a case for an orthodontic aligner 0158. Additionally, the rippled shape need not be sinusoidal waves. Rather, the rippled shape can comprise a series of triangular or rectangular shaped waves; however, the sinusoidal shaped waves can be more comfortable for a user, and could provide better seating performance when compared to other shapes. Additionally, some embodiments of the tool 0100 comprise a shape that is solid, rather than rippled, for the seating portion 0102. However, the seating portion 0102 can be advantageous. For example, having differently sized areas to bite on can facilitate seating an aligner 0158 at different portions of the teeth, such as the incisors or cuspids at the front 0108 of the mouth, or the premolars or molars towards the back of the mouth.
In some embodiments, the shapes of the handle portion 0104, the hook 0124, the seating portion 0102, the rippled shape of the seating portion 0102, or any combination thereof can vary as long as the shape still performs the respective function of each component as described herein.
Although embodiments of the invention have been described using the word “comprising,” additional embodiments can be created by replacing the word “comprising” with “consisting essentially of” or “consisting of.”
Although embodiments of the invention have been described using a first range with a first set of end points, additional embodiments can be created by replacing the first range with a narrower range whose endpoints are selected from any value contained in the first range.
Although embodiment of the invention have been described using a specific direction relative to a reference direction, additional embodiments can be created by indicating that specific direction can vary from the reference direction by no more than 45, 40, 35, 30, 25, 20, 15, 10, 5, 4, 3, 2 or 1 degrees.
Although the invention hereof has been described by way of preferred embodiments, it will be evident that other adaptations and modifications can be employed without departing from the spirit and scope thereof. The terms and expressions employed herein have been used as terms of description and not of limitation; and thus, there is no intent of excluding equivalents, but on the contrary it is intended to cover any and all equivalents that may be employed without departing from the spirit and scope of the invention.
