Problems solved by technology

[0010] Judging from the current situation, the research trend of the surface addition method has declined due to poor long-term stability, late coating dissolution and coating peeling.
The surface oxidation method is difficult to control the surface film layer, and requires multiple steps to obtain the required film layer. There are many process parameters to be controlled, the process is extremely complicated, and the long-term stability needs to be investigated.
[0011] Moreover, the surface treatment process of the dental implant disclosed in the prior art is complicated, and after sandblasting, simple acid etching cannot completely remove the sandblasting residual particles, which is not conducive to bone formation and osseointegration during subsequent implant implantation , also prone to inflammatory reactions around the implant

Abstract

The invention discloses a titanium alloy dental implant surface treatment process. After a pure titanium implant is widely applied clinically, the titanium alloy oral implant gradually develops. Compared with pure titanium, after alloy elements are added, the mechanical property, the strength, the corrosion resistance and the machinability of the material can be improved, the elastic modulus is reduced, and especially for a narrow-diameter implant, the fracture risk of the implant can be reduced. During treatment, TC4 bars are used as raw materials, a machining manufacturing process is adopted, subsequent surface treatment is carried out, the processed oral implant has good biological safety, osseointegration and mechanical properties, the implant surface can improve mechanical chimerism of the implant and surrounding bone tissue, the adsorption effect of bioactive molecules and cells is promoted, adhesion proliferation of the cells is facilitated, meanwhile, the surface energy and the wettability of the implant are also improved, the initial osseointegration speed of the implant is increased, and rapid osseointegration is realized; and the process is simple and suitable for commercial production.

Description

technical field [0001] The invention relates to the technical field of implants, in particular to a surface treatment process for titanium alloy dental implants. Background technique [0002] Titanium alloy materials are more and more widely used in the field of organ defect repair due to their excellent biocompatibility and excellent mechanical properties. Titanium-based biomaterials, mainly pure titanium or titanium alloys, have become the preferred materials for oral implants. However, from the perspective of clinical needs, there are still problems such as the need to improve the biological activity of the material, and improve the efficiency and effect of the combination of the material and bone tissue. Factors affecting osseointegration mainly include implant material, shape, surface morphology, chemical properties, loading conditions, shell operation, and individual differences in patients. In order to improve the initiative of implant osseointegration and promote go...
