Abstract

Introduction: Extreme repeated use of the dental implant handpiece may cause aging of the handpiece through heat generation of the implant motor and affect its lifespan. We aim to conduct an in-vitro study on the impact of the torque after repeated use of the implant handpiece. Materials and methods: Two types of implant handpiece systems NSK, and SAESHIN were applied. The output torque was calibrated using a digital torque gauge. The experiment was done under the setting torque value of 35 Ncm (implant placement torque) and 50 Ncm (overloading torque condition) and 30 times per set; a total of 5 sets were performed (N = 150). Results: NSK and SAESHIN implant handpieces depicted significant differences in output torque output at the setting torques of 35 Ncm and 50 Ncm (P <.001). The type of implant handpiece and repeated use influenced the output torque (P <.001). Conclusion: Notable changes were noted due to repeated use, and the implant handpiece should be achieved and repaired during long-term use. Moreover, for successful implant results in dental clinics, the output torque of the implant handpiece system should be checked before implant placement.
