[Photoelastic stress analysis of fixed-removable partial denture which had bar and Ceka-Anchor attachment].

Abstract

In our study, we constructed fixed-removable partial prosthesis, which are supported by teeth and tissue for patients who exhibited extensive tissue loss. In these prosthesis the localization of the precision attachments on the bar and the stress conducted to the abutment teeth by changing the number of splinted teeth and inclination of the bar were compared with photoelastic analyses and the results were evaluated. The photoelastic material used was Araldite/B and its catalyst was HT 901 fitalic anhydrate. The models constructed with these materials were examined in photoelastic polariscope and fringes occurred due to the force applied were photographed and analyzed.
