Abstract
Aim: This study aimed to evaluate the insertion torque and initial stability of single thread implants versus double and triple thread implants.
Methods: Forty two osteotomies were prepared in fresh bovine bone. The implants used in this study were 3 types according to the thread lead design,single thread implant, double and triple thread implants (n=14). Implants were inserted in bone blocks until reaching insertion torques (30 Ncm, 40Ncm and 50Ncm) then calibration of the part of implant inserted within bone was performed. The primary stability was assessed via resonance frequency analysis using the Osstell ISQ device. The removal torque of each implant is measured at torque 50N/cm. intergroup and intragroup comparisons were performed. The significance level was set at p ≤ 0.05 for all tests.
Results: Regarding , implant insertion torque the highest value was found in single thread group followed by double thread group, while the lowest value was found in triple thread group. Primary stability results and removal torque revealed that, the highest value were found in triple thread group, followed by double thread group, while the lowest value were found in single thread group and there was a significant difference between different groups (p < 0.001) in all measured outcomes.
Conclusions: When primary stability is a concern, as in low bone quality, double and triple threaded implants can provide greater primary stability and insertion torque. Double threaded implants combine optimum insertion speed and high primary stability and insertion torque in compromised situations.
