Screw shaped implants of Titanium-13Zirconium-6Niobium(newly developed), Titanium-6Zirconium-6Sn-
6Niobium(newly developed) and Titanium-6Aluminum-4Vanadium were machined with square top and inserted in rabbit bone for 3 months. Biomechanical tests(removal torque) showed Titanium-13Zirconium-6Niobium and Titanium-6Zirconium-6Sn-6Niobium to be more stable in the bone bed than those of Titanium-
6Aluminum-4Vanadium. Titanium-13Zirconium-6Niobium implants demonstrated a mean removal torque of 31.59Ncm while Titanium-6Aluminum-4Vanadium demonstrated a mean removal torque of 25.27Ncm and Titanium-6Zirconium-6Sn-6Niobium revealed a mean removal torque of 37.44Ncm and were statistically
significance in Wilcoxon Signed Rank test(P<0.05). Histomorphometrical comparisons were performed on 10㎛ thick undecalcified ground sections in the light microscope and Titanium-13Zirconium-6Niobium showed more mean bone-to-metal contact ratio than to other two titanium alloys but had no statistically significant differences were found among the three materials(P>0.01).
