20190247161
This application claims the priority benefit of Korean Patent Application No. 10-2018-0018500 filed on Feb. 14, 2018, in the Korean Intellectual Property Office, the disclosure of which is incorporated herein by reference for all purposes.
One or more example embodiments relate to a dental nozzle tip used to apply an impression material.
In general, impression materials may be materials used to imprint shapes of teeth and an abutment for dental treatment. Elastic impression materials may include, for example, alginic acid colloid, Thiokol, a rubber base, and a silicone rubber base. Inelastic impression materials may include, for example, a modeling compound and zinc eugenol. Various materials are selected and used based on purposes of the impression materials.
The impression material and a hardener may be stored in a pair of cartridges, respectively and discharged while being mixed with each other by a mixing tip.
The mixing tip may include a nozzle to discharge the impression material. The present disclosure relates to a nozzle tip attached to the nozzle to discharge the impression material.
In terms of the mixing tip, some techniques have been disclosed for, for example, devices that effectively mix impression materials and hardeners in a related field.
However, there has been little or no research on a method of effectively applying an impression material to a tooth and a nozzle tip for implementing the method, and an application device including the nozzle tip. Also, there is no widely known nozzle tip for ejecting an impression material to effectively apply a proper amount of impression material to a tooth, which may prevent a waste of material, and imprint a pattern of teeth with a minimal error. Accordingly, there is a desire for research on a device for effectively applying an impression material and an application method using the device.
An aspect provides a dental nozzle tip that evenly applies a proper amount of impression materials onto a tooth to accurately imprint a shape of the tooth while preventing a waste of materials using a simple tool to solve the aforementioned issues. Specifically, the dental nozzle tip may uniformly and relatively thinly apply bite registration materials that are used in a process of finding an accurate occlusion point.
However, tasks of the present disclosure are not limited to those mentioned above, and other matters not mentioned can be clearly understood by those skilled in the art from the following description.
According to an aspect, there is provided a dental nozzle tip for an impression material, the dental nozzle tip including an impression material inlet and an impression material outlet connected to the impression material inlet, wherein the impression material outlet is configured to have an expanded type opening at a tail end opposite to an end connected to the impression material inlet.
The tail end with the expanded type opening may have a width greater than a height.
A width of the tail end with the expanded type opening may be 5 millimeters (mm) to 13 mm.
A height of the tail end with the expanded type opening may be 4 mm to 5.5 mm.
At least a portion of a lower face of the impression material outlet may be cut in a direction from the expanded type opening toward the impression material inlet so as to be open.
The lower face of the impression material outlet may be cut by 1 mm to 2.5 mm from a virtual straight end line of the impression material inlet so as to be open.
A shape of a cut surface of the lower face of the impression material outlet may be concavely rounded toward the impression material inlet.
In a cross section of the expanded type opening, a portion corresponding to an upper face of the impression material outlet includes a straight section.
The impression material outlet may be bent to make an acute angle with a virtual line extending from the impression material inlet.
The dental nozzle tip may include a transparent material.
The dental nozzle tip may be formed to be integrated or combined with an impression material mixing tip.
A lower face of the dental nozzle tip may include a stepped portion and, in a cross section of the expanded type opening, a portion forming a lower step of the lower face of the impression material outlet may include a straight section.
According to another aspect, there is also provided a dental impression material applying device including the dental nozzle tip and a dental impression material mixing tip including a nozzle.
According to still another aspect, there is also provided a dental impression material applying method of applying an impression material to a tooth using the dental nozzle tip.
Additional aspects of example embodiments will be set forth in part in the description which follows and, in part, will be apparent from the description, or may be learned by practice of the disclosure.
These and/or other aspects, features, and advantages of the invention will become apparent and more readily appreciated from the following description of example embodiments, taken in conjunction with the accompanying drawings of which:
Hereinafter, example embodiments will be described in detail with reference to the accompanying drawings. Also, in the description of embodiments, detailed description of well-known related structures or functions will be omitted when it is deemed that such description will cause ambiguous interpretation of the present disclosure. Terminologies used herein are defined to appropriately describe the example embodiments of the present disclosure and thus may be changed depending on a user, the intent of an operator, or a custom. Accordingly, the terminologies must be defined based on the following overall description of this specification.
Throughout the specification, when an element, such as a layer, region, or substrate, is described as being “on,” “connected to,” or “coupled to” another element, it may be directly “on,” “connected to,” or “coupled to” the other element, or there may be one or more other elements intervening therebetween.
The terms “comprises,” “includes,” and “has” specify the presence of stated features, numbers, operations, members, elements, and/or combinations thereof, but do not preclude the presence or addition of one or more other features, numbers, operations, members, elements, and/or combinations thereof.
A dental nozzle tip for an impression material will be described in detail with reference to example embodiments and the accompanying drawings. It should be understood, however, that there is no intent to limit this disclosure to the particular example embodiments disclosed.
A dental nozzle tip for an impression material may include an impression material inlet and an impression material outlet connected to the impression material inlet. The impression material outlet may have an expanded type opening at a tail end opposite to an end connected to the impression material inlet.
The dental nozzle tip may include the impression material inlet having, for example, a columnar structure. The columnar structure of the impression material inlet may be in a shape of, for example, a cylinder, a square column, a pentagonal column, and a hexagonal column.
The impression material outlet may be connected to one end portion of the impression material inlet having the columnar structure. One end of the impression material outlet may be connected to the impression material inlet. Also, the impression material outlet may include the expanded type opening in the other end.
For example, the impression material inlet may have a tail end opposite to the end connected to the impression material outlet. The tail end may be connected to an impression material mixing tip and the like. In this example, an impression material mixed with a material such as a hardener may be introduced into the dental nozzle tip.
The impression material outlet may be formed to have a cross-sectional area gradually increasing in a direction from a portion connected to the impression material inlet toward the expanded type opening.
A cross-sectional area of the expanded type opening may be at least three times greater than a cross-sectional area of the impression material inlet.
In a cross section of an expanded type opening, a tail end of an expanded type opening may have a width greater than a height.
For example, the cross section of the expanded type opening may be in a rectangular shape or an oval shape having a horizontal axis greater in length than a vertical axis.
A width of the tail end of the expanded type opening may be 5 millimeters (mm) to 13 mm. For example, the width of the tail end of the expanded type opening may be 7 mm to 13 mm, or 5 mm to 10 mm A desired width of the tail end may be slightly greater than a width of a tooth, for example, a molar. Since a size of a tooth varies based on an age, a desired range may be determined based on a width of a target tooth within the aforementioned range.
A height of the tail end of the expanded type opening may be 4.0 mm to 5.5 mm For example, the height of the tail end of the expanded type opening may be 4.2 mm to 5.5 mm or 4.0 mm to 5.2 mm. The height of the tail end of the expanded type opening may be determined based on a height of the tooth. The height of the tail end of the expanded type opening may be within the aforementioned range to prevent the impression material from flowing unnecessarily when the impression material is discharged, which may lead to a waste of the impression material. Vertical and horizontal lengths of the expanded type opening may be associated with a size of the tooth to which the impression material is applied. The impression material discharged through the expanded type opening may be applied to the tooth, and fixed and hardened such that the tooth is imprinted on the impression material.
When lengths of the longest vertical and horizontal axes of the cross section of the expanded type opening are beyond the range, an excessively large or small amount of the impression material may be discharged at once and thus, an even application may not be performed.
The length of the longest horizontal axis of the expanded type opening may be slightly greater than or equal to a general width of a tooth. A practitioner may evenly apply the impression material to the tooth by discharging the impression material once without repetitive operations.
A portion of a lower face of an impression material outlet may be cut in a direction from an expanded type opening to the impression material inlet so as to be open.
When the portion of the lower face of the impression material outlet is cut and open, an impression material may be effectively and evenly discharged toward a tooth above which the dental nozzle tip is positioned.
When a practitioner discharges the impression material while slowly moving an impression material nozzle in a direction in which an upper face of the impression material outlet is located, the impression material discharged through an open structure of the impression material outlet may be effectively applied to the tooth. The impression material discharged through a cut area of the lower face may be evenly spread by the upper face that is uncut and relatively extended unlike the lower face, which may reduce an amount of impression material used and allows an even application of the impression material.
The lower face of the impression material outlet may be cut by 1 mm to 2.5 mm from a virtual straight end line of the impression material outlet so as to be open.
When a cut portion of the impression material outlet is less than 1 mm from the virtual straight end line, the impression material may be insufficiently discharged toward in a direction in which the lower face is located. When the cut portion is greater than 2.5 mm from the virtual straight end line, an excessively large amount of impression material may be discharged in the direction in which the lower face is located, so that the impression material is unevenly applied to the tooth.
A shape of a cut surface of the lower face of the impression material outlet may be concavely rounded toward the impression material inlet.
Through this, a relatively large amount of impression material may be discharged to a central portion of the tooth such that a dental impression may be effectively performed.
In a cross section of the expanded type opening, a portion corresponding to the upper face of the impression material outlet may include a straight section.
As shown in the cross section of the expanded type opening, the upper face of the impression material outlet may include a straight portion, thereby performing a function to evenly and smoothly spread the impression material discharged through the expanded type opening.
Through this, the discharged impression material may be applied to have a flat and even surface such that a shape of the tooth is reflected accurately and a waste of the impression material is prevented.
An impression material outlet may be bent to make an acute angle with a virtual line extending from an impression material inlet.
By applying a structure in which the impression material outlet is bent and connected to the impression material inlet, a practitioner may effectively apply the impression material to the tooth in a relaxed posture without need to fold a wrist by force to perform a dental impression.
The dental nozzle tip may include a transparent material.
For example, the dental nozzle tip may include silicon.
By using the transparent material, the practitioner may visually verify an amount of impression material remaining in the dental nozzle tip and an amount of impression material being discharged through the dental nozzle tip to adjust a dispensing speed while performing the dental impression.
A dental nozzle tip may be formed to be integrated or combined with an impression material mixing tip.
A lower face of a dental nozzle tip may include a stepped portion. An end shape of a portion forming a lower step of a lower face of an impression material outlet may include a straight section.
The portion forming the lower step may function to effectively discharge an impression material rearwardly when the impression material is applied.
The straight section provided at an end of the portion forming the lower step may be to ensure that a proper amount of impression material is applied to a tooth while the dental nozzle tip moves on the tooth, to form an impression material having an appropriate thickness on the tooth so as to obtain a solid body for effectively verifying a shape of the tooth after the impression material is hardened.
According to an example embodiment, a dental impression material applying device may include the dental nozzle tip and a dental impression material mixing tip including a nozzle.
According to an example embodiment, a dental impression material applying method may be of applying an impression material to a tooth using the dental nozzle tip.
According to example embodiments, it is possible to provide a nozzle tip attached to an end of a nozzle to evenly apply a proper amount of impression material onto a tooth, thereby accurately imprinting a shape of the tooth while preventing a waste of materials.
According to example embodiments, it is possible to provide a dental nozzle tip for an impression material to accurately verify an arrangement of teeth of a patient in order to perform an effective customized dental treatment and reduce a cost of the treatment by reducing an amount of materials used. Specifically, the dental nozzle tip may uniformly and relatively thinly apply bite registration materials that are used in a process of finding an accurate occlusion point.
A number of example embodiments have been described above. Nevertheless, it should be understood that various modifications may be made to these example embodiments. For example, suitable results may be achieved if the described techniques are performed in a different order and/or if components in a described system, architecture, device, or circuit are combined in a different manner and/or replaced or supplemented by other components or their equivalents. Accordingly, other implementations are within the scope of the following claims.
