Problems solved by technology

[0003] Clinically, the surface of the implant is usually a rough porous structure, which can improve the osseointegration rate of the implant and bone tissue, but the porous structure formed on the surface of the existing implant is not uniform, which leads to the integration with bone tissue Problems such as low strength and long healing time

Abstract

The invention relates to the technical field of dental implant, in particular to a surface treatment process of a titanium or titanium alloy dental implant. The surface treatment process comprises the following steps that firstly, a roughened surface is formed on a titanium or titanium alloy dental implant through 3D printing treatment, particles which are not tightly attached or are in a semi-molten state in 3D printing are removed through sand blasting treatment, the surface of the titanium or titanium alloy dental implant is further coarsened, an oxide layer and attached impurities on the surface of the titanium or titanium alloy dental implant can be removed by adopting a mixed solution of HF and H2SO4 for acid etching, alkali treatment is carried out by adopting a mixed solution of NaOH and H2O2, a nano-scale multi-layer stacked spongy or mesh-shaped interpenetrating structure is formed on the surface of the titanium or titanium alloy dental implant, so that the micro-morphology of the surface of the titanium or titanium alloy dental implant is effectively improved, the hydrophilicity, the bone bonding rate and the bonding strength of the surface of the titanium or titanium alloy dental implant are improved, and the healing time is effectively shortened.

Description

technical field [0001] The invention relates to the technical field of dental implants, in particular to a surface treatment process for a titanium or titanium alloy dental implant. Background technique [0002] Dental implant is a kind of missing tooth restoration method based on the lower structure implanted in bone tissue to support and retain the upper tooth restoration. It consists of two parts, the lower supporting implant and the upper dental restoration. It adopts artificial materials (such as metal, ceramics, etc.) way to connect and support the upper part of the dental restoration. [0003] Clinically, the surface of the implant is usually a rough porous structure, which can improve the osseointegration rate of the implant and bone tissue, but the porous structure formed on the surface of the existing implant is not uniform, which leads to the integration with bone tissue Low strength, long healing time and other issues. Contents of the invention [0004] The...
