Summary

This study looks at how different tightness levels (torque) of dental implant screws affect bone loss around the implant and patient satisfaction. Thirty adults needing three implants each will get one implant with a low-torque screw, one with a standard-torque screw, and one left under the gum. Researchers will measure bone loss, leakage, and comfort over time to find the best approach.
