White corundum for sandblasting of titanium alloy dental implants
High hardness: White corundum has a very high hardness, which enables it to effectively etch the surface of titanium alloy during sandblasting, forming the required roughness.
High purity: White corundum has high purity and almost no impurities, which ensures that it will not contaminate titanium alloy dental implants during sandblasting.
Good self sharpening property: White corundum abrasive has high self sharpening property and can maintain sharp edges during sandblasting, thereby improving sandblasting efficiency.
White color: White corundum has a pure white color, and sandblasting treatment will not change the original color of titanium alloy. It is suitable for surface treatment of titanium alloy dental implants with high color requirements.
2、 Sandblasting treatment process
In the sandblasting treatment of titanium alloy dental implants, the use of white corundum abrasive usually follows the following steps:
Pre treatment: Clean the titanium alloy dental implants to remove oil and esters, ensuring that the surface is clean and free of impurities.
Sandblasting treatment: Clamp the titanium alloy dental implant onto the fixture of the sandblasting equipment and use white corundum abrasive with appropriate particle size for surface sandblasting. The parameters such as sandblasting pressure, time, and abrasive particle size need to be adjusted according to specific requirements to ensure the desired roughness.
Subsequent processing: After sandblasting, titanium alloy dental implants are cleaned with deionized water and ultrasonic cleaning to remove residual abrasives and impurities. Then dry it to prepare for subsequent acid etching or other surface treatment processes.
3、 The advantages of white corundum in sandblasting of titanium alloy dental implants
Improving bone integration effect: White corundum sandblasting treatment can form a microstructure with micro roughness on the surface of titanium alloy, which is conducive to the adhesion, proliferation, and differentiation of osteoblasts, thereby improving the bone integration effect of titanium alloy dental implants.
Enhanced mechanical performance: The compressive stress generated by sandblasting treatment of white corundum can improve the mechanical properties of titanium alloy dental implants, especially their fatigue resistance, ensuring their stable performance during long-term use.
Reduce foreign body reactions: Due to the high purity and absence of impurities of white corundum, it will not contaminate titanium alloy dental implants during sandblasting, reducing the risk of foreign body reactions.
In summary, using white corundum for sandblasting of titanium alloy dental implants is an effective surface treatment strategy that can significantly improve the bone integration effect and mechanical properties of titanium alloy dental implants, while reducing the risk of foreign body reactions
