Abstract

The invention discloses a surface treatment process of a titanium alloy dental implant. After the pure titanium implant is widely used in clinic, the titanium alloy oral implant is gradually developed. Compared with pure titanium, the addition of alloying elements can improve the mechanical properties of the material, increase the strength, corrosion resistance, processability, and reduce the elastic modulus, especially for narrow-diameter implants, and reduce the risk of fracture. The present invention uses TC4 rods as raw materials for processing, adopts machining manufacturing process, and subsequently performs surface treatment. The processed oral implant has good biological safety, osseointegration, and mechanical properties. The surface of the implant can not only improve the quality of the implant The mechanical chimerism with the surrounding bone tissue promotes the adsorption of bioactive molecules and cells, which is beneficial to the adhesion and proliferation of cells, and at the same time improves the surface energy and wettability of the implant, accelerates the initial osseointegration speed of the implant, and achieves rapid osteosynthesis. Integration; simple process, 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...
