Introduction: Insertion torque imposes a direct effect on the stability of implants. Some studies suggest that high torque has resulted in bone necrosis while some suggest no impact on bone with high torque, the literature regarding insertion torque relationship to changes in bone is sparse.
Purpose: The rationale of this article is to critically evaluate the available scientific data on influence of insertion torque on implant success.
Materials and Methods: A Medline and manual search was done to recognize studies that are concerned with insertion torque related implant success rates from 1970 to 2017. The articles taken in this study includes data on insertion torque such as primary stability, bone quality and quantity, implant design and changes in bone related to high or low torque.
Results: The 28 included studies contains one randomized controlled trial, 12 prospective studies and 10 retrospective studies.
Conclusion: Insertion torque leads to primary stability of implants which ultimately contributes to implant success.
Keywords: Insertion torque, Primary stability, Bone density, Implant success.
