Abutment screw loosening is the second most common cause of failure of implant supported restoration. Krishnan V1, Tony Thomas C1, Sabu I1. Management of abutment screw loosening: review of literature and report of a case. J Indian Prosthodont Soc. 2014 Sep;14(3):208-14. doi: 10.1007/s13191-013-0330-2.
To minimize the the settling effect, abutment screws should be retightened at least twice at 30 N cm torque at a 10-min interval in all laboratory and clinical procedures.
