Abstract

The invention discloses an implant with biological activity and conditional antibiosis, and belongs to the technical field of dentistry, the implant comprises a support body, threads are arranged on the outer side of the support body, the support body is arranged to be of a porous structure, the porous structure provides a support for cell and new bone ingrowth and has osteoconductivity, silver nanoparticles are placed in pores of the porous structure, and the outer side of the porous structure is coated with a bioactive layer. The synergistic strain of the implant and the bone enables the masticatory force to be uniformly dispersed and conducted, the porous structure not only has the advantage of mechanical performance, but also can provide a support for cell and new bone ingrowth, has osteoconductivity, can be used as a biological medicine bin, and is provided with a coating to promote early osteogenesis, the formation of new bones and small blood vessels can be found in the second week to the fourth week after the implant is implanted, and the implant has biological activity. The coating also has a conditional pH antibacterial property, and can effectively prevent the occurrence of peri-implantitis.

Description

technical field [0001] The invention relates to the technical field of dentistry, in particular to an implant with biological activity and conditional antibacterial. Background technique [0002] The long-term osseointegration of current dental implants faces two major problems, one is mechanical and the other is biological. First of all, the impact of mechanical complications on long-term osseointegration is stress shielding. The stress and strain of bone and implant are inconsistent, the level of bone strain is low, no stimulation is obtained, bone is lost, and the strength is reduced. The second is the high elastic modulus of the implant, which is not prone to elastic deformation, so it is prone to stress concentration and tooth collapse when subjected to masticatory force. Therefore, it is necessary to design an implant with better mechanical and biological properties. Contents of the invention [0003] The purpose of the present invention is to provide an implant wi...
