Abstract
the control group, using the standard routine Branemark implant surgical method, was compared with the experimental 1 group, the fixture was put and then overtighten them, also compare with the experimental 2 group, the fixture was put and
overtighten,
and coverd the fixture head by Milipore Membrane.
The removal torque was measiured by Tohnichi Torque gauge manometer.
The contact of cortical layer with the screw of fixture was measured using the standard intraoral radiogram and after that the some corelation ship between cortical bony contact with implant and the removal torque was found.
1. There are no statically difference between the removal torque per cortical layer width of the overtightened Fixture and that of noram standard installation method. P=0.1441
2. There are no statically significant difference between the removal torque per cortical layer width of the overtightened Fixture and that of the group, whichwas covered by the Milipor membrane. P=0.066
3. The PEARSSON CORELATION COEFFICIENTS between cortical bony contact and removal torque are as follows:
Overtightened experimental group ; 0.91,
Nonovertightened control group ; 0.87
