Osseointegration and Histological Picture of Titanium Silicon Gallium Alloy vs. Titanium Silicon Alloy and Pure Titanium

Abstract

Background: Using titanium alloy with gallium and silicon could speed up the process of osseointegration, which would mean that titanium-silicon-gallium alloy could be used in more therapeutic situations. Objective: To evaluate the osseointegration and histological features of a newly fabricated Ti-Si-Ga alloy implant. Methods: Samples were fabricated utilizing the powder metallurgy technique. The titanium matrix was augmented with alloying components. The composite materials were produced by the compaction process at a pressure of 900 MPa, followed by sintering at a temperature of 800°C. For the in vivo test, ninety cylindrical specimens (3x6 mm in diameter and height, respectively) were prepared by using a wire-cut machine to cut the mentioned measurements from a sintered cylinder (15 mm in diameter and 6 mm in height) (6 cylinders for each group). Results: The Ti-Si-Ga group showed the highest bone formation area and higher push-out values than the commercially pure Ti and Ti-Si groups in this study. Conclusion: The use of gallium as an alloying element improved osseointegration.
