Abstract

The invention provides a dental implant with a micron-nanometer multi-grade micro-surface structure and a preparation method. The homogenous and uniform dental implant with the micron-nanometer multi-grade micro-structure is etched by using titanium as a substrate in a short time period, so that working efficiency is greatly improved and the problem of lacking bonding force between the surface structure and the substrate is solved.

Description

technical field [0001] The invention discloses a surface of a titanium dental implant with a micron-nano multi-level structure, and also provides a preparation method thereof, belonging to the medical technical field of artificial tooth root implants. Background technique [0002] Titanium metal has good and stable biocompatibility, can form osseointegration with bone tissue, and is widely used in the field of oral implantation as a dental implant material. However, titanium is a biologically inert material. In order to increase the contact area between dental implants and bone tissue, all oral implant systems are surface treated. Studies have shown that micron concaves can increase the mechanical chimerism of the bone and improve the mechanical properties of the implant; it can stabilize the deposition of fibrin blood clots on the surface of the implant and fix the fragile extracellular matrix scaffold. The nanosurface simulates the natural cell environment, increases pro...
