Abstract This study was performed to evaluate the effect of the metal and acetal denture bases around implant supported removable partial denture using photoelastic stress analysis method. The experiment was carried out on mandibular epoxy class I models with two parallel implants placed at lower first molar area and two groups were created: group I: Acetal denture base group II: Metallic denture base The stress was measured using photoelastic stress analysis machine by applying force on the metal plates which was adjusted on the occlusal surface of the acrylic record blocks. Regarding the models from the right and left side, stress analysis images were recorded for both groups and for both sides at stresses from 20 to 100 newton, using photoelastic machine and mean stress values were recorded for both groups, tabulated and statistically analyzed and the following result were obtained:- |
