An anti-resorptive implant

Abstract

The invention discloses an implant with bone absorption resistance. The implant comprises a body and an implantation hole. The implantation hole is formed inside the body, a cone is positioned on thelower side of a straight neck, the straight neck is provided with a neck ring, the neck ring is provided with first threads, a spiral structure is arranged on a surface of the cone, second threads arearranged on the spiral structure, cutting grooves are formed in lower structures of the spiral structure, a root is arranged at the bottom of the cone, and a third thread is arranged on a surface ofthe root; the implantation hole comprises a first conical body implantation hole, a second conical body implantation hole, a padlock component hole and a fastening threaded hole which are sequentiallyformed in positions from the straight neck to the root, the padlock component hole is formed in four clamp teeth which are uniformly distributed, and a circular connector is arranged inside the clampteeth. The implant has the advantages that injury on surrounding tissues can be reduced, and stress concentration of the root and damage to bone tissues during implantation can be reduced.

Description

Technical field [0001] The present invention relates to the technical field of medical equipment, and more specifically to an anti-bone resorption implant. Background technique [0002] Traditional implants use the Morse taper and the multi-angle anti-rotation structure of the implant hole to complete the stability of the fit between the whole and the abutment. The common problem is that the taper + anti-rotation part has a small contact area and the bite force cannot pass through the main body. Evenly conduction to the alveolar bone, resulting in stress concentration in the implant neck, poor connection between the implant and the abutment, and poor sealing. Abutment micro-movement and abutment-implantation are prone to occur under repeated loads. Micro gaps between the bodies cause peri-implant inflammation. [0003] The single-threaded thread of conventional implants has poor initial stability, has no forward and reverse cutting grooves, and is difficult to adjust the orientati...

AI Technical Summary

Problems solved by technology

[0002] The traditional implant uses Morse taper and multi-angle anti-rotation structure of the implant hole to complete the cooperation stability between the whole and the abutment. The common problem is that the taper + anti-rotation part has a small contact area, which will cause the occlusal force to fail to pass through the main body. It is evenly transmitted to the alveolar bone, thereby forming stress concentration in the implant neck, the firmness and sealing of the connection between the implant and the abutment are not good, and the abutment fretting and abutment-implantation are prone to occur under repeated loads Micro-gap between bodies, causing peri-implantitis

[0003] The initial stability of the single-head thread of the conventional implant is poor, there is no forward and reverse cutting groove, it is not easy to adjust the orientation, the inner hole is short, the stress cannot be transmitted downward, the stress concentration leads to fracture, the neck is tapered, and the cortical bone is squeezed. It is easy to cause bone resorption, the initial stability of the columnar shape is poor, and the flat and sharp design of the root end is poor in safety
