Problems solved by technology

Oral implant devices generally include implants, abutments, and connecting bolts. The widespread development and application of oral implant dentures have solved a series of aesthetic and functional problems caused by clinical tooth loss. However, the surgical operation process is complicated and the initial stability Poor sex, bone resorption occurs, it is difficult to seat between the implant and the abutment during the restoration process, and the slight movement of the abutment relative to the implant due to force during the chewing process causes gaps and leakage, and the upper parts will loosen These problems may lead to unsatisfactory implant repair effect or repair failure

Embodiment Construction

[0015] The invention is further described below in conjunction with the accompanying drawings:

[0016] As shown in the accompanying drawings, an oral implant with a conical surface and a rectangular key structure includes an implant 1 and its matching abutment 2 and fastening bolts 3. The shape of the implant 1 consists of a conical lower section 4 and a The cylindrical upper section 12 is composed of a thread 6 on the outside. The depth of the thread 6 on the conical part 4 is the same, and it gradually becomes shallower and exits on the cylindrical body 12. There is also a self-tapping cutting groove 5 on the lower section 4. There is an inner conical surface 10 under the inner upper end surface 11, which cooperates with the outer conical surface 19 on the base 2 to eliminate the gap and achieve good sealing performance, and the short cylindrical hole 9 under the inner conical surface 10 is used to prevent assembly. Interfering, the cylindrical hole (8) cooperates with the ...

Abstract

The invention relates to the field of dental repair technology, in particular to an oral implant with a conical surface and a rectangular key structure. The oral implant can be implanted in an alveolar bone in a surgery. The oral implant comprises an implant, and a base and a fastening bolt which are matched with the implant. The oral implant is characterized in that the implant consists of a cylindrical upper section part and a conical lower section part, wherein a conical hole is formed at the upper end of the interior of the implant, a cylindrical hole is formed at the middle section of the interior of the implant, a fastening screw hole is formed at the lower end of the interior of the implant, a cylindrical surface and the conical surface which are matched with the cylindrical hole and the conical hole are formed on the lower part of the base, and a key slot and a rectangular key which are matched with each other are formed on the cylindrical hole and the cylindrical surface respectively. The oral implant has the advantages of simple operation, short operation time, good initial stability after operation, good sealing property, high reliability, good base rotation resistance and platform conversion structure, bone absorption inhibition or removal and the like.

Description

Technical field: [0001] The invention relates to the technical field of dentistry, in particular to an oral implant with a conical surface and a rectangular key structure implanted in an alveolar bone through a surgical operation. Background technique: [0002] With the increasing demand for oral prosthodontics in modern society, traditional fixed dentures and removable dentures are becoming more and more difficult to meet people's wishes in many aspects. Some of the space, and continue to develop and mature, showing superiority in many aspects. Oral implant devices generally include implants, abutments, and connecting bolts. The wide development and application of oral implant dentures solves a series of aesthetic and functional problems caused by clinical tooth loss. However, the surgical operation process is complicated and the initial stability is stable. Poor performance, bone resorption occurs, it is difficult to seat between the implant and the abutment during the re...
