Description

Technical Field

[0001] The utility model relates to the technical field of dental implant abutments, and in particular to a dental implant abutment positioning device. Background Art

[0002] Dental implants refer to a technology that uses an artificial implant base structure placed under the bone tissue inside the oral cavity to support and fix artificial teeth to repair missing teeth. Both the implant base and the artificial teeth are combined with metal and ceramic structures to give them a higher hardness to adapt to different occlusal tasks.

[0003] A Chinese patent discloses a dental implant abutment positioning device with publication number CN219557603U. The technical solution disclosed in the patent document is as follows: it includes an abutment, an artificial tooth root and a crown. The lower part of the crown is fixedly connected to a plug rod, and the plug rod is distributed on the outer circumference of the crown. A hole is opened on the upper part of the abutment. The crown is engaged with the plug rod and the hole, and the lower side of the crown is bonded to the abutment.

[0004] In order to solve the problem of inaccurate positioning in the existing structure, the existing technology adopts the method of designing a rod and other structures to deal with it. However, there is still a situation where the positioning position of the crown cannot be fine-tuned. The artificial root, abutment and crown in this structure are positioned in a straight line, and the implant is installed manually, which inevitably leads to errors. If there is an error in the position of the implant, the position of the crown will also deviate. At this time, the position of the implant needs to be manually adjusted, which will cause great discomfort to the user. Utility Model Content

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0022] like Figure 1-Figure 5 As shown, the utility model provides a technical solution: a dental implant base positioning device, including an implant 1, a threaded groove 11 is provided on the top of the implant 1, and an adjustable crown positioning mechanism 2 is provided on the top of the implant 1. The adjustable crown positioning mechanism 2 includes an implant base 21, and the bottom of the implant base 21 is fixedly connected with a threaded column 22, and the threaded column 22 is threadedly connected in the inner cavity of the threaded groove 11. The inner top of the implant base 21 is rotatably connected with a rotating ball 23, and the top of the rotating ball 23 is fixedly installed with a connecting platform 24, and the top of the connecting platform 24 is movably connected with a crown platform 25. Through the design of the threaded column 22 and the threaded groove 11, the implant 1 and the implant base 21 are connected by threads, and through By controlling the rotation degree of the threaded column 22, the height of the implant base 21 relative to the implant 1 can be adjusted. Through the design of the rotating ball 23, the implant base 21 and the connecting platform 24 are rotatably connected, and the orientation of the connecting platform 24 can be adjusted relative to the implant base 21, thereby achieving the function of fine-tuning the crown position on the top of the crown platform 25, avoiding the problem that re-implanting the implant 1 will cause great discomfort to the user. After the threaded column 22 is rotated into place inside the thread groove 11, glue is added to the connection between the thread groove 11 and the threaded column 22 for positioning. After the position of the connecting platform 24 is adjusted into place, glue is added to the connection between the rotating ball 23 and the implant base 21 for positioning.

[0023] As an implementation method in this embodiment, Figures 1-4As shown, a strip groove 241 is provided on the top of the connecting platform 24, and a hemispherical groove 242 is provided on the front and back of the inner wall of the strip groove 241. A positioning plug strip 243 is movably inserted in the inner cavity of the strip groove 241, and the positioning plug strip 243 is fixedly installed on the bottom of the crown platform 25. A through groove is provided on the side of the positioning plug strip 243, and a partition 244 is fixedly installed in the middle of the inner cavity of the through groove. An arc-shaped metal elastic part 245 is fixedly installed on the front and back of the partition 244. A cylindrical groove communicating with the inner cavity of the through groove is provided on the front and back of the positioning plug strip 243, and a sliding ball head column 246 is slidably connected to the inner wall of the cylindrical groove. One end of the sliding ball head column 246 is movably connected to the outer surface of the arc-shaped metal elastic part 245, and the other end of the sliding ball head column 246 extends into the inner cavity of the hemispherical groove 242, connecting After the positioning of the platform 24 is completed, the positioning plug-in strip 243 is inserted into the inside of the strip groove 241, and glue is pre-added to the connection between the positioning plug-in strip 243 and the strip groove 241. When the positioning plug-in strip 243 is inserted into the inside of the strip groove 241, the sliding ball head column 246 will slide toward the direction of the partition 244 to shrink, and at the same time compress the arc-shaped metal spring part 245, and the arc-shaped metal spring part 245 will produce elastic deformation. After the positioning plug-in strip 243 is inserted into place, the initial elastic force of the arc-shaped metal spring part 245 makes the sliding ball head column 246 inserted into the inside of the hemispherical groove 242. When the sliding ball head column 246 contacts the inner wall of the hemispherical groove 242, a slight impact will be generated. Through this impact feedback, the operator can know that the positioning plug-in strip 243 has been inserted into place, which is convenient for the operator to stop applying force in time.

[0024] As an implementation method in this embodiment, Figure 5 As shown, the crown platform 25 is fixedly connected with a raised block 251, and the top of the raised block 251 is fixedly connected with a forked extension piece 252. During the production of the crown, the crown can be connected to the top of the crown platform 25, and at the same time, the raised block 251 and the forked extension piece 252 are located inside the crown. The design of the raised block 251 and the forked extension piece 252 can improve the stability of the connection between the crown and the crown platform 25.

[0025] Working principle: When in use, the implant 1 is implanted in the oral cavity in advance, and then the rotation degree of the threaded column 22 is manually controlled. After the threaded column 22 is rotated into place inside the threaded groove 11, glue is added to the connection between the threaded groove 11 and the threaded column 22 for positioning. Then, the orientation of the connecting platform 24 is manually adjusted relative to the implant base 21. After the position of the connecting platform 24 is adjusted into place, glue is added to the connection between the rotating ball 23 and the implant base 21 for positioning. The position adjustment of the connecting platform 24 is completed. During production, the crown is pre-connected to the crown platform 25, and then the positioning plug-in strip 243 is plugged into the strip groove 241. At the same time, glue is added to the connection between the positioning plug-in strip 243 and the strip groove 241 to complete the installation of the crown.

[0026] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same.
