Statement of problem: It is difficult about assessing the loosening tendency of conical connection type implant after cyclic loading with diamond like carbon coating one-piece abutments, and also about the retightening effect.

Purpose: This study was performed to investigate the influence of one-piece abutment screw retightening after 5.0¡¿10 4 cyclic loading and Diamond like coating

Material and methods: Thirty two ITI implant were divided to 4 groups. Group 1,3-titanium abutment, group 2,4 - diamond like carbon coated abutment. Group 1,2 - 20.0¡¿10 4 cyclic loading after 5.0¡¿10 4 cyclic loading, Group 3,4- after 20.0¡¿10 4 Cyclic loading. After cyclic loading, periotest values were taken and removal torque values of abutments were measured with a digital torque gauge.

Results: 1. The removal torque of group 2 after 5.0¡¿10 4 cyclic loading is slightly greater than the other groups but not significantly higher than others (P>0.05). 2. The final removal torque values after 20.0¡¿10 4 cyclic loading of group 1 is bigger than group 3, and group 2 is bigger than group 4, but not significantly higher (P>0.05). 3. The final removal torque values after 20.0¡¿10 4 cyclic loading of all groups are not significantly different (P>0.05).
