Description

Technical Field

[0001] This utility model relates to the technical field of dental treatment instruments, and in particular to an orthodontic traction device for connecting implants. Background Technology

[0002] Clinically, patients with both missing teeth and malocclusion often require combined orthodontic and implant treatment. Orthodontic treatment typically involves applying corrective forces to the teeth using brackets, archwires, or anchorage screws, and is a lengthy process. Traditional implant treatment employs a two-stage surgical approach: first, the implant is placed, and after osseointegration with the alveolar bone, the abutment and crown are installed, which also takes considerable time. For these patients, performing implant and orthodontic treatment in stages significantly prolongs the overall treatment period. Current techniques, when using implants as orthodontic anchorage, require fabricating a temporary crown after osseointegration and then bonding a traction device to the temporary crown, complicating the clinical procedure. Therefore, there is an urgent need for an integrated device that combines implant and orthodontic traction functions to shorten the treatment period and simplify the procedure. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide an orthodontic traction device for connecting implants. Through structural innovation, the implant can be used directly as orthodontic anchorage during osseointegration and supports rapid switching to the crown restoration stage.

[0004] To achieve the above objectives, this utility model provides an orthodontic traction device for connecting implants, comprising an implant, a pull rod, and a temporary abutment and a crown abutment that are replaceably installed on top of the implant. The lower parts of both the temporary abutment and the crown abutment are formed with connecting portions of uniform specifications. The top surface of the implant has an internal threaded groove for threaded insertion of the connecting portion. The upper part of the temporary abutment is formed with a support sleeve for the tail end of the pull rod, and a pressure cap is detachably installed on the upper part of the temporary abutment. The bottom surface of the pressure cap mates with the top surface of the temporary abutment to clamp the pull rod. The head end of the pull rod is formed with a hook portion.

[0005] Furthermore, the tail end of the tie rod is integrally formed with a collar that fits into the support sleeve.

[0006] Furthermore, the bottom surface of the pressure cap and / or the temporary base is formed with anti-slip protrusions for contacting the surface of the tie rod.

[0007] Furthermore, the top surface of the pressure cap has a vertical through hole that fits into the support sleeve, and the pressure cap and the support sleeve are fastened together by a preset locking screw.

[0008] The advantages of this invention, which adopts the above-mentioned solution, are as follows: 1) Functional integration: The implant provides orthodontic anchorage through a temporary abutment and tie rods. After orthodontic treatment, it is replaced with a crown abutment to achieve implant restoration. 2) Shortened cycle: Implantation and orthodontic treatment are performed simultaneously, avoiding the waste of time in staged treatment. 3) Structural compatibility: The standardized connection design simplifies abutment replacement operations and reduces clinical complexity.

[0017] To more fully illustrate this utility model, a detailed description will be provided below in conjunction with the accompanying drawings. The drawings depict preferred embodiments of this utility model. However, it is worth noting that this utility model is not limited to these specific forms and can be implemented in various ways. These embodiments are provided to enable the reader to gain a deeper understanding of this utility model.

[0018] As attached Figure 1-7As shown in this embodiment, an orthodontic traction device for connecting implants includes an implant 1, a tie rod 2, and a temporary abutment 3 and a crown abutment 6, which are replaceably installed on top of the implant 1. The implant 1 is the core component of the dental implant system, surgically implanted into the alveolar bone to replace the natural tooth root and provide support for the superstructure (crown). The crown abutment 6 is the key component connecting the implant 1 and the crown. Based on current clinical practice in dental implants, the implant 1, crown abutment 6, and crown are often implanted and installed separately through multiple surgical procedures, resulting in a long installation period. The specific implantation process and principles are well-known technologies and will not be elaborated here. Orthodontics, on the other hand, applies continuous and gentle force to the teeth using braces (brackets, archwires, clear aligners, elastic bands, etc.) to adjust tooth position, resulting in a long treatment period. Therefore, for patients requiring both implantation and orthodontic treatment, the anchorage function of the implant 1 can be effectively utilized after implantation, significantly shortening the overall treatment period.

[0019] In this embodiment, the lower part of the implant 1 is a nail-like structure with external threads, and its top surface has an internal threaded groove 11. The lower parts of the temporary abutment 3 and the crown abutment 6 are both formed with a connection part 31 of uniform specifications. The connection part 31 of the temporary abutment 3 and the crown abutment 6 can be replaced by threaded fitting with the internal threaded groove 11. The internal threaded groove 11 and the connection part 31 adopt a standardized thread interface (such as M2-M4 specification) to ensure that the temporary abutment 3 and the crown abutment 6 can be quickly replaced.

[0020] In this embodiment, the crown abutment 6 is used to replace the temporary abutment 3 after orthodontic treatment to connect the implant 1 and the crown. The upper part of the temporary abutment 3 is formed with a support sleeve 32 for the tail end of the tie rod 2 to be fitted. Specifically, the tail end of the tie rod 2 is integrally formed with a collar 22 that fits into the support sleeve 32. By fitting the center hole of the collar 22 into the support sleeve 32, the tie rod 2 is correspondingly mounted on the support sleeve 32. At this time, the collar 22 at the tail end of the tie rod 2 and the support sleeve 32 have a clearance fit, ensuring that the tie rod 2 can be adjusted at multiple angles. Furthermore, the tie rod 2 has a sheet-like structure, and the center hole of its collar 22 matches the shape of the support sleeve 32.

[0021] In this embodiment, the end of the pull rod 2 is formed with a hook portion 21. The hook portion can be designed as a closed loop or an open U-shape to adapt to different orthodontic devices (not shown in the figure, this device is an existing component and will not be described in detail here). In use, the end of the elastic rubber band extended from the orthodontic device can be hung on the hook portion to provide stable support for tooth movement. Secondly, pull rods 2 of different lengths (5-15mm) can be provided to adapt to the actual spacing in the patient's mouth.

[0022] In this embodiment, a pressure cap 4 is detachably installed on the upper part of the temporary base 3. The bottom surface of the pressure cap 4 mates with the top surface of the temporary base 3 to clamp the tie rod 2. A connecting through hole 41 is opened on the bottom and top surfaces of the pressure cap 4 to fit into the support sleeve 32, and the fit is secured by a locking screw 5 (the locking screw 5 passes through the connecting through hole 41 and mates with a pre-set fixing screw hole at the top of the support sleeve 32). Specifically, after the tie rod 2 and the support sleeve 32 are nested in advance and the tie rod 2 is rotated and adjusted to an appropriate position around the support sleeve 32, the pressure cap 4 is nested with the support sleeve 32 through the connecting through hole 41 (achieving a pre-installation effect). Finally, the pressure cap 4 and the support sleeve 32 are secured by the locking screw 5, so that the bottom surface of the pressure cap 4 mates with the top surface of the temporary base 3 to clamp the tie rod 2.

[0023] In this embodiment, anti-slip protrusions 33 are provided on the bottom surface of the pressure cap 4 and / or the surface of the temporary base 3 to enhance the friction on the pull rod 2. The anti-slip protrusions 33 are micro-serrations or dot-shaped protrusions to prevent the pull rod 2 from slipping under force. For ease of explanation, both the bottom surface of the pressure cap 4 and the surface of the temporary base 3 are provided with anti-slip protrusions 33. Those skilled in the art can choose as needed, or they can choose to provide anti-slip protrusions 33 on only one of the bottom surface of the pressure cap 4 and the surface of the temporary base 3.

[0024] In summary, the traction device of this embodiment features integrated functionality, with the implant 1 providing orthodontic anchorage load through the temporary abutment 3 and the tie rod 2. This embodiment can be widely applied in the field of combined implant and orthodontic treatment, and is especially suitable for implant patients requiring strong anchorage orthodontic traction. It has advantages such as simple clinical operation, short treatment cycle, and controllable cost.

[0025] The embodiments described above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any way. Any modifications or alterations made by those skilled in the art to the technical solution of this utility model without departing from its scope are equivalent embodiments of this utility model. Therefore, all equivalent changes made based on the concept of this utility model without departing from its scope should be covered within the protection scope of this utility model.
