Abstract
|
|
|
There are report that the removal strength of Surface roughness of Sa from 1 to 1.5
Sa ws strength than that of 0.4 or 2.0 the removal torque of screw implant heat-treated
was 2.37N㎝ and that of untreated control specimen was 1.68N㎝. it was statistically
tested by Wilcoxon Mached-pairs singned-Rank test(p=0.014) F of 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.
