Abstract

The invention particularly discloses a dental implant. The dental implant comprises a personalized base table, an auxiliary base table and an implant body which are sequentially connected from top tobottom, wherein the implant body comprises an implant neck part, an implant body part and an implant root part; the diameters of the implant neck part, the implant body part and the implant root partare sequentially decreased and have the taper; dense screw threads are arranged on the outer surface of the implant neck part; sparse screw threads are arranged on the outer surface of the implant body part; deep screw threads are arranged on the lower end part of the implant root part; a center hole is formed in the lower end part of the implant root part towards the inside of the implant body; osseointegration holes in staggered distribution are formed in the outer surface of the implant root part; and the osseointegration holes extend to the inside of the implant root part and communicate with the center holes. The dental implant provided by the invention has the advantages that the biocompatibility is good; the osseointegration incidence rate is high; the success rate is high; and however, when the marginal bone loss is excessive, and after the life quality decreases, the dental implant can be easily pulled away.

Description

technical field [0001] The invention belongs to the field of oral implants, and in particular relates to a dental implant. Background technique [0002] In recent years, with the development of science and technology and the improvement of people's living standards, people pay more and more attention to the loss of teeth.
