Description

Technical Field

[0001] The utility model belongs to the technical field of medical devices, and specifically relates to a tooth implant substitute. Background Technique

[0002] In the intraoral dental implant technology, traditional substitutes are mainly used in plaster models. Their main function is to accurately transfer the implant information in the patient's oral cavity to the plaster model, facilitating the technicians in the dental laboratory to design superstructures such as abutments on the substitutes.

[0003] For example, a 3D substitute for oral implant with the publication number CN219516619U improves its stability by opening fixing grooves and positioning card slots on its outer wall. However, due to the small size of the substitute, opening multiple grooves on its outer wall requires high precision for the equipment, resulting in a high cost of the substitute. To solve the above problems, a tooth implant substitute is proposed. Content of the Utility Model

[0004] The purpose of the utility model is to propose a tooth implant substitute to solve the above problems.

[0005] The technical scheme adopted by the utility model is as follows: A tooth implant substitute, including:

[0006] A positioning seat, on the upper surface of which a boss is integrally provided;

[0007] A substitute body, which is threadedly connected to the upper surface of the positioning seat. One side of the upper end of the substitute body is provided with a flat part, and two annular grooves are equidistantly arranged on the outer wall of the upper end of the substitute body.

[0008] Through the above technical scheme, by providing a flat part on the outer wall of the substitute body, when the substitute body is installed in the plaster model, the flat part prevents it from shaking during the installation of the abutment. At the same time, adopting the structure of the flat part enables the substitute body to be completed with only a single cutting, greatly reducing the production cost of the substitute. By providing annular grooves, on the one hand, it is convenient to position the substitute during installation. On the other hand, after the substitute body is installed in the plaster model, the plaster can enter the internal part of the annular grooves to make the plaster closely combined with the substitute body.

[0009] In a preferred embodiment, an external thread is provided on the outer wall of the boss, and an internal thread adapted to the boss is provided at the bottom of the substitute body.

[0010] Through the above technical scheme, the substitute body and the positioning seat are installed by threads, which is convenient for installation and disassembly.

[0011] In a preferred embodiment, a connecting groove is provided at the bottom of the positioning seat.

[0012] Through the above technical solution, after the positioning seat is installed in the gypsum model, the gypsum can enter the inside of the connecting groove to closely combine the gypsum with the positioning group seat.

[0013] In a preferred embodiment, the connecting groove is of a triangular structure.

[0014] Through the above technical solution, the triangular structure has a pointing function, which is convenient for the recording and installation of the positioning seat.

[0015] In a preferred embodiment, both the positioning seat and the substitute body are made of titanium alloy by molding.

[0016] In a preferred embodiment, a base mounting hole is provided at the top of the substitute body.

[0017] Through the above technical solution, the abutment is fixedly installed on the top of the substitute body through the base mounting hole.

[0018] In summary, due to the adoption of the above technical solution, the beneficial effect of the present utility model is that the present utility model proposes a tooth implant substitute.

[0019] 1. By providing a flat portion on the outer wall of the substitute body, after the substitute body is installed in the gypsum model, the flat portion prevents it from shaking during the installation of the abutment. At the same time, with the structure of the flat portion, the substitute body only needs to be cut once to complete, greatly reducing the production cost of the substitute. By providing an annular groove, on the one hand, it is convenient to position the substitute during installation, and on the other hand, after the substitute body is installed in the gypsum model, the gypsum can enter the inside of the annular groove to closely combine the gypsum with the substitute body.

[0020] 2. After the positioning seat is installed in the gypsum model, the gypsum can enter the inside of the connecting groove to closely combine the gypsum with the positioning group seat. The triangular structure has a pointing function, which is convenient for the recording and installation of the positioning seat. BRIEF DESCRIPTION OF THE DRAWINGS
