Pourable implant with rooting and fixing functions

Abstract

The invention belongs to the technical field of dental department, and relates to a pourable implant with rooting and fixing functions. The implant comprises a pile part and an abutment part, wherein the pile part is used for implanting jaws; the abutment part is used for mounting false teeth; the pile part is integrally connected with the abutment part; the interior of the pile part is provided with a pouring passage in the vertical direction; a plurality of pouring holes are formed in the surface of the pile part and are communicated with the pouring passage. The implant has the advantages that the structure is simple, and the design concept is skillful and reasonable; a bone cement pile in the pouring passage, and a bone cement which permeates into a planting lacuna tissue through a pouring hole can effectively a root structure, so that the implant is fixedly arranged in a planting lacuna from shallow to deep in multiple-layer and all-bearing ways, and the stress in the vertical direction can be dispersed and borne; the bone cement forms a separating film between the implant and the bone tissue, the elasticity modulus is approximate to the elastic modulus of cancellous bone, the settling of the implant can be effectively blocked, and the use time of the implanted teeth can be prolonged.

Description

technical field [0001] The invention belongs to the technical field of dentistry, and relates to an implant that can be perfused and rooted. Background technique [0002] Dental implants are currently the main method of repairing missing teeth. Dental implants are mainly composed of implants, abutments, and crowns. Implants are the part of implants implanted in the alveolar bone, which need to have good biocompatibility and rigidity (large elastic modulus). Poor implant fixation or loosening and substantial subsidence will directly lead to implant failure. [0003] Alveolar bone is cancellous bone, which is characterized by a bread-like porous structure with a small elastic modulus. [0004] Due to the strong force of chewing, the current implants are made of metal materials with good biocompatibility and high strength. Its appearance is a metal screw with a blunt nail tip ( figure 1 ). As the theory of osseointegration is widely accepted clinically, the surface of the i...

Problems solved by technology

[0005] However, the problem is clearly

On the one hand, after tooth loss, the surrounding alveolar bone will shrink and defect, which will lead to insufficient bone volume in the planned implant socket (similar to insufficient soil thickness when planting trees), and bone augmentation treatment (bone grafting) is required. , split increment, etc.), which makes the implantation time longer, more difficult, more painful for patients, and more expensive

More importantly, on the other hand, since the elastic modulus of metal implants and alveolar bone is very different, when the osseointegration formed in the non-stressed (chewing) state bears the strong stress generated during chewing, the elastic modulus The alveolar bone with a small amount will be repeatedly squeezed, cut, or even broken down by the metal implant with a large elastic modulus, resulting in a short service life and poor implant effect
