OBJECTIVES This study evaluated the microleakage at the implant/abutment interface of external hexagon (eH) implants and abutments with different amounts of bacteria and tightening torques. MATERIAL AND METHODS A bacterial suspension was prepared to inoculate the implants. The first phase of this study used nine EH implants and abutments that were divided into three groups with different amou...

Background: To compare the loss of preload in absence loading and after a fixed number cyclic loadings on 7-mm distal cantilever two different connection systems using all-on-four prosthetic model. Methods: Two equal models an edentulous mandible rehabilitated with technique types abutment system (MUA OT-Bridge) supporting hybrid prosthesis, were used. Initial torque values fixing screw, ten mi...
