Abstract:

This study systematically evaluated nine surface treatment conditions on titanium dental implant fixtures, combining Sandblasted Large Grit Acid-etched (SLA) with anodizing methods. A total of 112 samples were characterized using FESEM, EDAX, MTT, wettability, surface energy, and osseointegration analyses. Among the tested protocols, the SLA+Anodizing process with the following parameters proved most effective: sandblasting with 75 µm particles at 4 bar and 30° angle, acid etching at 75°C for 6 minutes, and anodizing at 100 V for 5 minutes. This optimized surface demonstrated superior outcomes, including 97% cell viability, enhanced osseointegration within twelve days, and a chemical composition consistent with Grade 5 titanium alloy (Ti-6Al-4V), typically comprising approximately 90% Ti, 6% Al, 4% V, and trace amounts of O, Fe, and other elements.
