There are report that the removal strength of Surface roughness of Sa from 1 to 1.5 Sa ws strongth than that of 0.4 or 2.0 the removal torque of screw implant heat-treated was 2.37Ncm and that of untreated control specimen was 1.68Ncm. it was statistically tested by Wilcoxon Mached-pairs singned-Rank test(p =0.014) F o f Analysis of varience was 13.22 and p= 0.002 And the surface roughness of untreated Control group Ra=0.592 and the Ra values of heat treated experimental group was 0.393 this means that heat treatment could decrease the roughness of surface however could increase the removal torques
