Background The aim of this study is to evaluate the biomechanical behavior of the mesial and distal off-axial extensions of implant-retained prostheses in the posterior maxilla with different prosthetic materials using finite element analysis (FEA). Methods Three dimensional (3D) finite element models with three implant configurations and prosthet...

Background: In this study, the biomechanical behavior of the mesial and distal off-axial extensions of implant-retained prostheses in the posterior maxilla with different prosthetic materials were investigated using FEA. Methods: 3D finite element models with three implant prosthetic designs: fixed-fixed, mesial cantilever, and distal cantilever w...

Objective: Evaluate the effect of Implant prosthetic designs and restorative material on the stress concentrationof 3-unit implant-supported restoration with two restorative materials. Material and Methods: Six differentscrew-retained prostheses models were virtually designed and divided according to design: fixed bridge (FB),cantilever bridge (CB)...

Objective: The purpose of this in vitro study was to evaluate the effect of different implant prosthetic designswith two restorative materials on biomechanical behaviour using strain gauge analysis. Material and Methods:6 different screw-retained implant restorations were designed and fabricated using a CAD/CAM system. Theseimplants were divided in...

Objectives The choice of material and sequence of finishing & polishing of pressed ceramics which are broadly used for indirect restorations applying different polishing methods on the glazed ceramic surfaces has not been agreed on yet so a comparison of different finishing protocols on the mechanical strength of pressed ceramics in a clinical simu...
