A method of designing and manufacturing of the surface structure of the iconic membrane tooth implant

Abstract

A method for designing and manufacturing the surface structure of a periodontal ligament imitation dental implant of the present invention has the following steps: 1) the dental implant is divided into 2 layers, and a print file is generated with 3D printing software; 2) the inner layer is a solid structure , the outer layer is a gradient hollow structure with gradually increasing porosity from the inside to the outside; 3) The porosity of the innermost layer of the hollow structure is 0, and the porosity of the outermost layer is 50-80%; 4) The shape of the trabecular pores and gaps It is a bone-like trabecular structure; 5) It is printed by a laser cladding 3D printer; 6) The material used can be pure titanium, titanium alloy, zirconia or titanium-zirconium-based amorphous metal glass; 8) It can be used as a dental implant after sterilization product use. The invention can effectively improve the osteogenic performance of the surface of the dental implant, imitate the mechanical buffer effect of the periodontal ligament to a certain extent, reduce the local stress concentration under the state of masticatory function, and can pass through the complex bone interface structure of the dental implant, Significantly reduce the occurrence and progression of inflammation around dental implants, and improve the long-term success rate of dental implant restoration.

Description

technical field [0001] The invention relates to a manufacturing method of oral medical products, in particular to a design and manufacturing method of imitating the surface structure of a periodontal ligament dental implant. Background technique [0002] The existing dental implant surface structure is not a three-dimensional penetrating structure. Although it can be used on dental implants, the main problems are: first, the surface structure of the implant is a single flat interface, and the surface osseointegration area without through pores is relatively small. Small, insufficient osseointegration, and can not effectively block the rapid invasion of periodontal bacteria, can not reduce the occurrence and progress of peri-implant inflammation; second, the elastic modulus of implant materials and human bone tissue is very different, prone to stress barrier, causing stress concentration at the implant-osseointegration interface, which cannot mimic the cushioning properties o...
