Biomechanical Behavior of Different Implant Supported Hybrid Designs with Two Different Ceramic Materials (Finite Element & Strain Gauge Analysis)

Abstract

This study was conducted to investigate the strains and stresses values at the implant, restoration and bone generated from vertical occlusal forces by both in vitro strain gauge and finite element analysis methods. Within the limitations of this study, the following conclusions were drawn: 1. Design of implant restoration has high impact on the stress and strain values generated by vertical load at the implant-restoration regardless the material type. 2. Material of implant restoration has high impact on the stress and strain values generated by vertical load at the implant-restoration regardless the restoration design. 3. The use of combined PEEK&ZR implant restoration material can resist occlusal vertical load better than Full ZR implant restoration. 4. Cantilever design showed higher stress and strain values than separate restoration design and fixed bridge restoration design regardless restorative material type.
