The screws are the weakest parts of the implant-prosthetic system, their loosening is an important sign that can alert and warn of a possible fracture.  Loosening the abutment screw is the second most common cause of implant supported restoration failure.  It is recommended that the tightening torque be reapplied at least twice at a 10-minute interval for all laboratory and clinical procedures to minimize the loosening effect of the abutment screws.
