The Evaluation of Unscrewing Torque Values of Implant-Abutment Connections: An In Vitro Study
Purpose:
This study investigated the stability of titanium screws in implant-abutment connections by measuring the force necessary to induce unscrewing.
Materials And Methods:
A total of 60 implant-abutment couplings were assigned to two groups (n = 30 each). The sequence 10-20-32 Ncm was tested in Group 1; the sequence 10-20-32-32-32 Ncm was tested in Group 2. The force necessary to unscrew each abutment-implant sample was recorded and statistically analyzed. The significance level was set at P < .05.
Results:
Significant differences were found between the two sequences. Group 2 required higher forces than Group 1 to unscrew.
Conclusion:
The stability of the implant-abutment joint may be improved by tightening with the sequence 10-20-32-32-32 Ncm.
