Finite element stress analysis on the influence of cuspal angle and superstructure materials in an implant-supported prosthesis
Purpose: To investigate the effect of superstructure materials and cuspal angle in an implant-supported fixed partial denture. Materials and Methods: This finite element analysis study was carried out with varying cuspal angulations of 0°, 20° and 33° and superstructure materials. The simulated mod...
