Abstract

Background: Implant stability is an indicator of the osseointegration of dental implants. The insertion torque of the implant is the amount of frictional resistance the implant receives during its insertion. It has been suggested that acceleration and improvement of implant success can be accomplished by applying high insertion torques. On the other hand, other studies suggested that high insertion torque values ​​could result in large compressive forces on the bone surrounding the implant. Aim: Evaluation the effect of high insertion torques of dental implants on implant stability quotient (ISQ) in the posterior mandible.Materials and Methods: The sample consisted of 20 implants divided into two groups, group A included 10 implants of high torque (>50 N/cm), the group B included 10 implants of low torque (25-35 N/cm), implant type is (Megagen, Anyone), the initial stability of it in both study groups was measured by (OSTELL) device after inserting an implant with a high torque, an implant with a low torque, and it was evaluated immediately after implantation and after 6 months.Results: The significance level value is much smaller than the value 0.05 regardless of the time period studied, that is, at the 95% confidence level there are statistically significant differences in the average values ​​of ISQ immediately after implantation and after six months between the two study groups, the values ​​of implant stability immediately after implantation and after six months in the group of implants with high torque of insertion were greater compared with the group of implants with low insertion torque.Conclusion: The high insertion torque (> 50 N/cm) leads to higher initial stability of the implant immediately after implantation and after 6 months compared with the low insertion torque.
