Evaluation of Heat Transfer to the Implant-Bone Interface During Removal of Metal Copings Cemented onto Titanium Abutments

R emoval of a cement-retained implant-supported restoration may be necessary when prosthetic complications such as loosening of an abutment screw or fracture of veneering ceramic occur. If the adhesive bond of the cement cannot be broken, the restoration can be removed by drilling through the restoration screw access channel or sectioning the restoration with a high-speed dental handpiece.1 These interventions may generate frictional heat, and overheating the implant-bone interface along the implant body may result in bone necrosis leading to implant failure.2
