Bridge abutment component for dental implant

Abstract

The invention discloses a bridge abutment component for a dental implant. An inserting section of a gingiva abutment part is mounted in an inner hole of an implant; a central through hole of the gingiva abutment part is a stepped hole; a central positioning bolt penetrates through the stepped hole and is screwed into internal threads of the implant for realizing fixing connection of the gingiva abutment part and the implant; a bridge abutment is arranged on an inverted conical frustum at the upper part of a gingiva abutment; the internal threads are arranged on the inner wall of the inverted conical frustum; a set screw is screwed into the gingiva abutment through an upper port of the bridge abutment and fastening connection of the bridge abutment and the gingiva abutment and the implant is realized; as the set screw is connected with the internal threads of the inverted conical frustum of the gingiva abutment rather than is screwed into internal threads of the central positioning bolt, the diameter of the set screw is greatly increased, further strain strength of the set screw is enhanced, and the problem that the set screw is easy to break in clinical application is solved; meanwhile, a hollow structure of the central positioning bolt is changed into a solid structure, so that the strength of the central positioning bolt is enhanced; meanwhile, the problem that the central positioning bolt is easy to break in clinical application is solved, mostly common complications of implant denture are greatly avoided and the long-term success rate of the bridge abutment component isensured.

Description

technical field [0001] The invention belongs to the technical field of dental implants, and relates to a three-stage implant bridge abutment matching assembly. Background technique [0002] Dental implants, as artificial tooth roots for denture retention devices, have been widely used in the restoration of single teeth, partial teeth, and complete tooth loss in the oral cavity. How to choose scientific and reasonable restorative accessories from various forms of implant superstructures for the production of final bridge restorations is one of the factors that reduce implant complications and ensure the long-term success rate of implants. At present, the two-stage dental implant combined into two parts of implant and gingival abutment is mainly used in the implant bonding technology for repairing single teeth and partial tooth loss in the oral cavity, while the combination of implant, gingival abutment and bridge base The three-part three-segment implant is mostly used in th...

Problems solved by technology

[0006] In order to solve the problem of broken central positioning bolts and fixed screws in the prior art, the present invention provides a bridge abutment for dental implants. The inner wall of the inverted conical circular platform on the upper part of the gingival abutment is provided with a bridge for fastening connection. The inner thread structure of the abutment allows the fixing screw to be directly screwed into the inner thread of the inner wall of the inverted cone-shaped round table of the gingival abutment through the upper opening of the bridge abutment, which greatly increases the thread diameter of the fixing screw, thus solving the existing problem The small thread diameter of the technical fixing screw leads to problems of low strength, poor stress resistance, and easy breakage; also because the fixing screw is a fastening connection with the inner thread of the inverted conical round table of the gingival abutment, it does not need to be screwed in In the internal thread of the central positioning bolt, the hollow structure of the central positioning bolt in the prior art is changed into a solid structure, which increases the strength, enhances its strain resistance, and avoids the problem that the central positioning bolt is prone to breakage
