Effect of tightening protocols on abutment screw loosening and morphological changes in two-piece zirconia implants: A comparative study using cyclic torsional loading
Abutment screw retightening does not consistently enhance torque maintenance under torsional loading. The implant material affects torque retention and deformation, where titanium implants demonstrating greater stability than zirconia implants.
