Problems solved by technology

[0004] The research and application of bionics on implant morphology should be given sufficient attention. Although there are a few imitation root-shaped implants on the market, there are few varieties, and most of them are simply connected by fixed-length cylindrical segments and different-length conical segments. However, the analysis of the shape of human ...

Abstract

The invention relates to an oral implant device and an implant length computation method in the field of oral implantation restoration technique. The oral implant device comprises an implant, a base and a fastening bolt; the implant is formed by a columnar head, a conical middle part and a spherical tail end, wherein the head, the middle part and the tail end are smoothly connected in bullet shape; a columnar step cavity is arranged at the head of the implant; a rectangular key is arranged at the upper part of the cavity and a screw hole connected with the fastening bolt is arranged at the lower part of the cavity; and a rectangular key slot matched with the upper part of the cavity is arranged at the lower part of the base. With bionic characteristic in shape, , the implant of the invention can be better combined with the alveolar bone to realize the biomechanical effect similar to the natural tooth; in addition, the implant can be combined with the base in conical surface manner with good sealing performance and has implant base platform conversion structure; and moreover, the implant has the advantages of simple structure and precise and stable cooperation between the implant and the base and can reduce the bone absorption after the implantation.

Description

Technical field: [0001] The invention relates to the technical field of oral implant restoration, in particular to a root-like oral implant device applied to the oral implant restoration technology. technical background: [0002] In the 1960s, Br? of Gothenburg University in Sweden? Professor Nemark conducted research on the interface between oral implant materials and bone implants, created the "osseointegration" theory of titanium, and laid a theoretical foundation for the application of modern oral implantology. Dental implant application technology is the most important part of modern oral implantology. The widespread development and application of oral implant dentures have solved a series of aesthetic and functional problems caused by clinical tooth loss. [0003] However, the shape of widely used cylindrical implants is quite different from that of natural teeth. The main force or force component during chewing is transmitted along the axial direction of the tooth r...
