Abstract
Description
Technical Field
[0001] This invention provides a positioning structure for orthodontic appliances that makes the brackets less likely to fall off and is easy to install. Background Technology
[0002] During orthodontic treatment, orthodontic brackets are fixed to the tooth surface, and the archwire passes through the archwire groove on the bracket. The corrective force of the archwire is transmitted to the tooth through the bracket, causing the tooth to move as expected, so as to achieve the purpose of straightening the tooth. Therefore, the placement of the brackets on the tooth has strict requirements, as this is an important factor affecting the orthodontic effect.
[0003] Traditional orthodontic bracket bonding relies primarily on the dentist's clinical experience for manual retention. The direction and angle of bracket retention cannot be precisely determined, and the procedure is complex, consuming a significant amount of the dentist's time. Furthermore, patients often remain with their mouths open for extended periods to cooperate with the dentist, leading to fatigue. The reliance on dentist experience also makes it prone to misjudgment or bracket detachment, requiring rebonding and leaving adhesive residue on the patient's teeth. The amount of adhesive used during bonding also depends on the dentist's experience. If the dentist corrects bracket placement on the patient's teeth, excessive adhesive may accumulate, requiring time and effort to remove. This process is time-consuming, complex, and demands a high level of clinical skill from the dentist.
[0004] Therefore, a positioning device has emerged on the market, such as patent CN113180860 "An adhesive positioning device for orthodontics", which includes at least one positioning unit. The positioning unit includes a tooth positioning structure and a bracket positioning structure connected to each other. The tooth positioning structure is used to abut against the tooth apex surface, and the bracket positioning structure is used to clamp and release the bracket. The bracket positioning structure includes a first elastic clamping block and a second elastic clamping block arranged on the mesial and distal sides of the bracket. A gap is formed between the first elastic clamping block and the second elastic clamping block, which extends along the gingival direction to the gingival end of the first elastic clamping block and the second elastic clamping block. The gap between the first elastic clamping block and the second elastic clamping block allows the first elastic clamping block and the second elastic clamping block to cooperate with each other to stably clamp the bracket. When it is necessary to release the bracket and apply force to remove the adhesive positioning device, the two elastic clamping blocks will deform outward in the direction of the gap, so that the adhesive positioning device can be easily disassembled.
[0005] However, the aforementioned adhesive positioning device for orthodontics does have the following problems and shortcomings that require improvement:
[0006] When this positioning device is in operation, it is not perfect in terms of the integrity of the fixation. It only uses the first and second clamping pieces to limit the left and right sides of the tray, the third and fourth clamping pieces to limit the rear side of the tray, and the first and second recesses to limit the lower side of the tray. As a result, the tray may still detach. This is because it only limits the four sides of the tray, including the left, right, rear, and lower sides, and lacks the limit of one side. This makes it easy for the tray to detach from the side that lacks the limit.
[0007] In addition, although the gap between the first elastic clamping block and the second elastic clamping block provides the elastic clamping function of the bracket during positioning, the single gap means that the first elastic clamping block and the second elastic clamping block only have elastic stress in two directions, which is poor in terms of elasticity. This makes it difficult to install the bracket when it is placed into the first elastic clamping block and the second elastic clamping block, and there is a concern that it may be too tight.
[0008] Therefore, how to solve the aforementioned common problems and shortcomings is the direction that the creator of this utility model and related manufacturers in this industry want to research and improve. Utility Model Content
[0009] In view of the above-mentioned shortcomings, the applicant of this utility model collected relevant information, conducted multiple evaluations and considerations, and made continuous attempts and modifications, and thus designed a positioning structure for a dental orthodontic appliance that is not easy to detach and is easy to install.
[0010] The main purpose of this utility model is to generate five-directional limiting in the up, down, left, right and back directions by the joint clamping of the first elastic support part, the first elastic limiting part, the second elastic support part and the third elastic support part, so that the orthodontic appliance can be set more accurately and is not easy to fall off when placed on the tooth surface, and can be more simple and quick to assemble and disassemble.
[0011] The structure that achieves the aforementioned main objectives includes a base, a first elastic clamping member, a first elastic supporting portion, a first elastic limiting portion, a second elastic clamping member, a second elastic supporting portion, a third elastic clamping member, a third elastic supporting portion, and an accommodating space. The first elastic clamping member, the second elastic clamping member, and the third elastic clamping member are all disposed on the base. The first elastic clamping member includes a first elastic supporting portion and a first elastic limiting portion. The second elastic clamping member includes a second elastic supporting portion. The third elastic clamping member includes a third elastic supporting portion. The accommodating space is formed by the first elastic clamping member, the second elastic clamping member, and the third elastic clamping member surrounding the first elastic clamping member, the second elastic clamping member, and the third elastic clamping member.
[0012] Before the orthodontic appliance is attached to the tooth surface, it is first attached to the positioning structure. During the attachment process, one side of the orthodontic appliance will simultaneously push the first elastic clamp, the second elastic clamp, and the third elastic clamp outward. When the first elastic support, the first elastic limiting part, the second elastic support, and the third elastic supporting part restrict the position of the orthodontic appliance within the receiving space, the orthodontic appliance can achieve directional limitation in the up, down, left, right, and back directions, achieving the advantage of not being easy to detach. Furthermore, due to the design of the three independent components of the first elastic clamp, the second elastic clamp, and the third elastic clamp, the orthodontic appliance is easier to install and remove.
[0013] By employing the above-mentioned technology, the problems of brackets easily detaching from the side without restraint and poor elasticity in a commonly used adhesive positioning device for orthodontics, which makes it difficult to install the brackets when they are placed in the first elastic clamping block and the second elastic clamping block, and causes concerns about excessive tightness, can be overcome, thus achieving the advantages of this utility model.

[0041] To achieve the above objectives and effects, the technical means and structure adopted by this utility model are described in detail below with reference to the accompanying drawings, in order to provide a complete understanding of the preferred embodiments of this utility model.
[0042] Please refer to Figures 1 to 5 The figure shown is a perspective view to a cross-sectional perspective view of a single positioning structure according to a first preferred embodiment of the present invention. It can be clearly seen from the figure that the present invention includes:
[0043] Base 1;
[0044] The first elastic clamping member 2 provided on the base 1 includes a first elastic abutting part 21 and a first elastic limiting part 22 formed by bending the first elastic abutting part 21 away from the base 1, and the first elastic limiting part 22 extends in the X-axis direction.
[0045] The second elastic clamping member 3, which is disposed on the base 1 and located on one side of the first elastic clamping member 2, includes a second elastic abutment portion 31.
[0046] The third elastic clamping member 4, disposed on the base 1 and located on the opposite side of the second elastic clamping member 3, includes a third elastic abutment portion 41; and
[0047] A receiving space 5 is formed between the first elastic clamp 2, the second elastic clamp 3, and the third elastic clamp 4 to accommodate the orthodontic appliance.
[0048] Among them, the first elastic clamping member 2, the second elastic clamping member 3, and the third elastic clamping member 4 have gaps between them, so that they can operate independently. This allows the clamping direction to be dispersed when the orthodontic appliance is installed, so that the orthodontic appliance can be subjected to clamping force from three directions. This not only maintains the clamping force, but also makes it easier for users to install and remove the appliance.
[0049] The first elastic limiting part 22 and the first elastic resisting part 21 are arranged in an orthogonal pattern.
[0050] The first elastic limiting part 22 is provided with a first elastic locking part 23 at one end away from the first elastic supporting part 21, so that after the orthodontic appliance is installed in the accommodating space 5, it can be locked by the first elastic locking part 23 to prevent it from easily detaching from the X-axis direction, and the first elastic locking part 23 extends towards the Y-axis direction.
[0051] The second elastic support portion 31 is provided with at least one second elastic locking portion 32, and the third elastic support portion 41 is provided with at least one third elastic locking portion 42. This allows the orthodontic appliance, after being installed in the receiving space 5, to be locked by the third elastic locking portion 42, preventing it from easily detaching from the X-axis direction. Furthermore, in this embodiment, one second elastic locking portion 32 and one third elastic locking portion 42 are used as an example; when there are two, they can be arranged vertically along the Y-axis or longitudinally along the X-axis.
[0052] The second elastic support portion 31 is provided with at least one second elastic clamping portion 33, and the third elastic support portion 41 is provided with at least one third elastic clamping portion 43. After the orthodontic appliance is installed in the receiving space 5, it is firmly fixed by the left and right sides of the second elastic clamping portion 33 and the third elastic clamping portion 43, making it difficult for the orthodontic appliance to shift again. Of course, this fixing force is less than the force required for the user to remove the positioning structure, so that the user can easily remove the positioning structure. Furthermore, in this embodiment, one second elastic clamping portion 33 and one third elastic clamping portion 43 are used as an example. When there are two, they can be arranged vertically along the Y-axis or horizontally along the X-axis.
[0053] Among them, a curved surface 6 is provided on the base 1 opposite to the first elastic limiting part 22, so that the design of the curved surface 6 can conform to the surface shape of the orthodontic appliance and effectively prevent the orthodontic appliance from shaking or shifting unnecessarily.
[0054] The second elastic support part 31 and the third elastic support part 41 are tilted in the same direction, which makes it easy to put the orthodontic appliance into or remove it from the receiving space 5. Since the teeth may be irregularly arranged, the design of tilting in the same direction allows the user to easily put in or remove the orthodontic appliance by simply adjusting the angle.
[0055] The second elastic clamping member 3 and the third elastic clamping member 4 are gradually widened in shape, narrower at the bottom and wider at the top, so that the second elastic clamping member 3 and the third elastic clamping member 4 have sufficient elasticity to clamp the orthodontic appliance.
[0056] The height of the first elastic limiting part 22 is greater than that of the second elastic clamping part 3 and the third elastic clamping part 4, so that when the orthodontic appliance is housed in the receiving space 5, it will not be too tightly compressed, and the orthodontic appliance can also be properly positioned.
[0057] Furthermore, the implementation method can be referred to in the same way. Figures 1 to 7 The figure shown is a perspective view of a single positioning structure combined with a dental orthodontic appliance according to the first preferred embodiment of the present invention. As can be clearly seen from the figure, multiple positioning structures can be manufactured according to the patient's tooth arrangement pattern. In particular, when there are multiple positioning structures, multiple connecting members 7 are provided between each base 1, so that each positioning structure can have a large drop between each other through the connecting members 7, thereby achieving advantages such as not being easily deformed and structural reinforcement, in order to cooperate with the patient's tooth position adjustment. In addition, the above-mentioned manufacturing of multiple positioning structures according to the patient's tooth arrangement pattern is a general way of establishing positioning structures, which is not the main claim of this invention, so it will not be described in detail.
[0058] Once all positioning structures are in place, the orthodontic appliance 8 can be inserted into the receiving space 5 from the X-axis direction. During the insertion process, the first elastic clamp 2 will be pushed back and deformed by the outer surface of the orthodontic appliance 8. The second elastic clamp 3 and the third elastic clamp 4 will be pushed to the left and right by the outer surface of the orthodontic appliance 8 and deformed. A part of the orthodontic appliance 8 will be positioned to a certain extent by the first elastic locking part 23, the second elastic locking part 32, and the third elastic locking part 42, effectively preventing the orthodontic appliance 8 from easily detaching from the X-axis direction. In addition, the second elastic clamping part 33 and the third elastic clamping part 43 simultaneously exert a clamping effect on the left and right sides (i.e., the Z-axis direction) of the orthodontic appliance 8, and the first elastic supporting part 21 and the curved surface 6 simultaneously provide a positioning effect on the orthodontic appliance 8 in the Y-axis direction. Thus, it is evident that this invention can achieve multi-directional positioning effects for the orthodontic appliance 8 in the up, down, left, right, front, and back directions. Finally, each of the orthodontic appliances 8 that has been installed on the positioning structure is glued to the outer surface of the tooth 9. Then, the positioning structure is removed, so that each orthodontic appliance 8 is removed from the receiving space 5 in the X-axis direction. This completes the configuration of the orthodontic appliances 8. This invention allows users to easily attach or remove the orthodontic appliances 8 to the tooth 9 with precise alignment, effectively avoiding problems caused by poor adhesion due to inaccurate alignment, and also preventing discomfort to the patient during the removal process.
[0059] Please refer to Figure 8The figure shown is a perspective view of a single positioning structure according to a second preferred embodiment of the present invention. As can be clearly seen from the figure, the positioning structure of this embodiment mainly includes a base 1, a first elastic clamping member 2, a first elastic abutment portion 21, a first elastic limiting portion 22, a second elastic clamping member 3, a second elastic abutment portion 31, a third elastic clamping member 4, a third elastic abutment portion 41, and a receiving space 5. It is evident that the structure of this embodiment is largely similar to the above embodiments. The only differences between this embodiment and the above embodiments are that this embodiment does not have the first elastic locking portion, the second elastic locking portion, the third elastic locking portion, the second elastic pressing portion, the third elastic pressing portion, the curved surface, the second elastic abutment portion and the third elastic abutment portion tilting in the same direction, the second elastic clamping member and the third elastic clamping member having a gradually widening shape that is narrower at the bottom and wider at the top, and the height of the first elastic limiting portion being greater than that of the second elastic clamping member and the third elastic clamping member. Therefore, regarding the base 1, the first elastic clamping member 2, the first elastic abutment portion 21, and the first elastic limiting portion... 22. The second elastic clamping member 3, the second elastic abutment part 31, the third elastic clamping member 4, and the third elastic abutment part 41 can still achieve a certain positioning effect for the positioning function of the orthodontic appliance. The vertical direction is achieved through the first elastic limiting part 22 of the first elastic clamping member 2 and its base 1, while the horizontal direction is achieved through the second elastic abutment part 31 of the second elastic clamping member 3 and the third elastic abutment part 41 of the third elastic clamping member 4, and the rear direction is achieved through the first elastic abutment part 21. It is evident that the positioning effect of the orthodontic appliance in the vertical, horizontal, left and right and rear directions can indeed be achieved.

Any simple modifications and equivalent structural changes made by using the contents of the present utility model specification and drawings as examples should also be included in the patent scope of the present utility model.
