Description

Technical Field

[0001] The utility model belongs to the technical field of dental instruments, and specifically relates to a scanning and positioning part for dental implants. Background Art

[0002] During the process of dental implantation, the scanning rod is a crucial component in the process of fabricating CAD / CAM personalized implant abutments. It is mainly used to obtain the position and orientation data of dental implants in the oral cavity during the scanning of the position and orientation of dental implants in the oral cavity by a model scanner or an intraoral scanner. By surface matching the data with the model in the implant database in the design software, implant information can be obtained, thus completing personalized restoration.

[0003] A scanning rod and a dental implant assembly disclosed in the patent with the publication number CN 213098448 U. Among them, the scanning rod is connected to the implant. The upper end of the implant is recessed with a receiving groove. The scanning rod includes a scanning section, a limiting section, and a matching section connected in sequence. A fastening hole is provided in the scanning rod, and the fastening hole penetrates both ends of the scanning rod. The end face of the limiting section facing away from the scanning section is recessed to form a limiting groove. Part of the matching section is located in the limiting groove, and the other part extends out of the limiting groove and is inserted into the receiving groove, so that the upper end face of the implant is attached to the groove wall of the limiting groove.

[0004] In the actual use of the existing dental implant scanning and positioning part, the applicant found that: due to the different heights of people's teeth, the heights of the missing teeth are different, so the heights of the dental implant sockets are also different. The existing dental scanning and positioning parts are all of an integral structure, and the height of the positioning part is fixed. Therefore, in many cases, the height of the positioning part will exceed the dental implant socket after installation, and it cannot be adjusted adaptively according to the height of the missing dental implant sockets of different people. At this time, when the scanning head scans the teeth, the positioning part is likely to touch and interfere with the scanning head. Especially for the teeth near the throat, the opening and closing angle of the mandible is limited, and the moving space of the scanning head is small. The too-high positioning part will expand the moving range of the scanning head, resulting in insufficient space for the scanning head to scan. To solve the above-mentioned problems, a scanning and positioning part for dental implants is proposed. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a scanning and positioning part for dental implants to solve the above-mentioned problems.

A hexagonal cylindrical socket is provided at the top of the implant, and a threaded hole is provided at the bottom of the hexagonal cylindrical socket. A hexagonal prism is constructed at the lower part of the positioning body, and the hexagonal prism is adaptively inserted into the hexagonal cylindrical socket. A hexagonal hole is provided on the adjusting shim, and the adjusting shim is adaptively sleeved on the hexagonal prism through the hexagonal hole. A trapezoidal through hole is provided in the positioning body, and a connecting bolt is inserted into the trapezoidal through hole, and the connecting bolt is threadedly connected to the threaded hole.

[0007] In a preferred embodiment, a positioning surface is provided on the positioning body.

[0008] In a preferred embodiment, the implant is a tapered structure with a wider top and a narrower bottom, and a screw-in thread is provided on the outer wall of the implant.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0016] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the embodiments of the present utility model. Obviously, the described embodiments are some, but not all, of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0017] The following will be combined with Figures 1 - 3 to provide a detailed description of the dental implant scanning positioning member in the embodiments of the present utility model. Embodiment

[0018] The dental implant scanning positioning member provided by the embodiments of the present utility model, referring to Figures 1 to 3 as shown, includes an implant 1. A screwing thread 11 is provided on the outer wall of the implant 1. A hexagonal cylindrical socket 4 is opened at the top of the implant 1, and a threaded hole 5 is opened at the bottom of the hexagonal cylindrical socket 4. With this structure, the implant 1 is screwed into the pre-drilled hole in the tooth bone through the screwing thread 11, so as to embed the implant 1 into the tooth bone. The hexagonal cylindrical socket 4 facilitates the wrench to rotate the implant 1, and the threaded hole 5 facilitates bolt connection and also facilitates the installation of the healing abutment in the later stage.

[0019] Referring to Figures 1 to 3 as shown, the implant 1 is a tapered structure that is wider at the top and narrower at the bottom. With this tapered structure, the implant 1 is convenient to accurately insert into the pre-drilled hole, and as the implant 1 is screwed in, the implant 1 will be tightened more and more, thus ensuring the installation strength of the implant 1.

[0020] Referring to Figures 1 to 3 as shown, it includes a positioning body 2. A hexagonal prism 6 is constructed at the lower part of the positioning body 2. The hexagonal prism 6 is adaptively inserted into the hexagonal cylindrical socket 4. A trapezoidal through hole 8 is opened in the positioning body 2, and a connecting bolt 9 is inserted into the trapezoidal through hole 8. The connecting bolt 9 is threadedly connected to the threaded hole 5. With this structure, the positioning member 2 is inserted into the hexagonal cylindrical socket 4 of the implant 1 through the hexagonal prism 6 to position the position of the positioning member 2. Then, the operator passes the connecting bolt 9 through the trapezoidal through hole 8 and connects it to the threaded hole 5 of the implant 1, so as to lock and fix the positioning member 2 in the implant 1, and then complete the installation of the positioning body 2. Then, during scanning, the orientation and angle of the implant 1 can be positioned through the positioning body 2, thus forming a basis for the modeling of the dental implant in the later stage.

[0021] Referring to Figures 1 to 3 as shown, a positioning surface 10 is provided on the positioning body 2, which is convenient for scanning and identification positioning.

[0022] Referring to Figures 1 to 3As shown, it includes a number of adjusting shims 3. A hexagonal hole 7 is provided on the adjusting shim 3. The adjusting shim 3 is adaptively sleeved on the hexagonal prism 6 through the hexagonal hole 7. With this structure, personnel can set the adjusting shim 3 between the positioning body 2 and the implant 1. Thus, personnel can adjust the height of the positioning body 2 by increasing or decreasing the adjusting shim 3, so as to prevent the positioning body 2 from exceeding the alveolar ridge, which is convenient for subsequent scanning operations.

[0023] Reference Figures 1 to 3 As shown, the outer diameter of the upper part of the implant 1 is the same as the outer diameter of the positioning body 2, and the outer diameter of the positioning body 2 is the same as the outer diameter of the adjusting shim 3.

[0024] The implementation principle of the dental implant scanning positioning member in the embodiment of the present application is as follows: When installing the positioning member, personnel measure the depth of the missing alveolar ridge. Personnel sleeve the corresponding number of adjusting shims 3 on the hexagonal prism 6, so that the thickness of the adjusting shim 3 plus the height of the positioning body 2 is adapted to the depth of the alveolar ridge. Then, personnel insert the hexagonal prism 6 of the positioning member 2 into the hexagonal cylindrical socket 4 of the implant 1 to position the position of the positioning member 2. Then, personnel pass the connecting bolt 9 through the trapezoidal through hole 8 and connect it to the threaded hole 5 of the implant 1, so as to lock the positioning member 2 and the adjusting shim 3 on the implant 1, and then complete the installation of the positioning body 2. Then, during scanning, the orientation and angle of the implant 1 can be positioned through the positioning body 2, thus forming a basis for the subsequent modeling of dental implants.

[0025] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
