Abstract

Controversy over combining teeth and implants for support of fixed partial dentures still remains. The aim of this study is to analyze the biomechanical behavior of the implant-tooth supported fixed prostheses, with rigid and non-rigid connection. Different modes of connection that have been employed will be explored. Model represents the lost of lower first molar, an upper first premolar (like a natural tooth) and an implant corresponding to upper second molar. External and internal hexagon and morse taper implants will be evaluated. Fixed prostheses with rigid and non-rigid connection will be made. Intracoronal attachments (7,0x2,6mm) will be used in non-rigid connection, positioned in the premolar distal face. Tests of cyclic load, torque and destorque will be performed. Photoelastic stress and finite element analysis will be performed in order to observe the stress to the natural tooth, peri-implant bone and implant. (AU)
