Embodiment 1

[0064] Embodiment 1 Application of titanium alloy of the present invention as a sandblasting medium for dental implants

[0065] 1. Preparation before sandblasting

[0066] (1) Sand composition and size

[0067] Composition: 6Al4V titanium alloy -- TC4 (that is, Ti-6Al-4V)

[0068] Size: 60 mesh

[0069] (2) Implant cleaning

[0070] Submerge the implant in an aqueous solution of detergent. The aqueous solution of detergent is prepared by adding water to ordinary household detergent at a ratio of 1:30, and then placed in an ultrasonic oscillator for 20 minutes to remove any damage caused by the previous mechanical processing on the surface of the implant. Oil and other dirt, rinse with purified water and dry.

[0071] (3) Choose a sandblasting machine that can be used for metal sandblasting

[0072] The sandblasting machine structure schematic diagram that the present invention selects is as figure 2 As shown, it includes an operation room 2 with a sandblasting head, a ...

Abstract

The invention discloses a new use of titanium alloy, i.e. application as a dental implant sandblasting medium. The invention also discloses a dental implant sandblasting roughening method. The method comprises the steps of: a. selecting titanium alloy as the blasting medium; b. cleaning an implant; and c. blasting sand by a sandblasting machine. According to the invention, the titanium alloy Ti-6Al-4V is adopted as the sandblasting medium, and at the same time the specific sandblasting machine, sandblasting head and clamp are employed to reach the purposes of roughening the implant surface, enhancing the bonding strength between the implant and bone tissue, and accelerating osseointegration. Also, the risk of pollution by undesirable chemical components can be avoided, and elements incompatible with implant chemical components cannot be left on the implant surface subjected to sandblasting treatment.

Description

technical field [0001] The invention relates to the application of a titanium alloy as a sandblasting medium for dental implants. Background technique [0002] When the implant is placed in the jawbone, osseointegration with the surrounding tissue is the criterion for successful implantation. However, its main components are completely different from bone tissue. As a biologically inert material, it cannot induce new bone growth after implantation, and it is integrated with bone tissue. Weaker and takes longer to heal. [0003] With the in-depth research on implant materials, scholars have found that the rough surface has better osteoinductivity, the implant is more firmly integrated with the surrounding bone tissue, and the long-term effect of implant is better than that of the smooth surface implant. At present, surface modification is mainly to improve the wear resistance, corrosion resistance and biological properties (including biocompatibility and bioactivity) of impl...
