The aim of this randomized clinical trial to compare the implant positional accuracy of robotic system-assisted implant surgery with that of static system-assisted implant surgery. Patients will be recruited and randomly assigned to either the robotic surgery group or the static navigation surgery group to evaluate the accuracy of the implants in both groups and to compare patient-reported and physician-reported outcomes of the two approaches.

Dental implants have been widely used for replacing the lost natural teeth, with evidence of long-term success and improvement of patients' quality of life. Nevertheless, proper implant position is considered today an essential prerequisite for ensuring successful treatment outcomes, as well as long-term maintenance of the prosthesis and the peri-implant tissue health.Therefore, we plan to conduct this randomized clinical trialto compare the implant positional accuracy of robotic system-assisted implant surgery with that of static system-assisted implant surgery. Patients will be recruited and randomly assigned to either the robotic surgery group or the static navigation surgery group to evaluate the accuracy of the implants in both groups and to compare patient-reported and physician-reported outcomes of the two approaches.
