Flexural Strength of Surface-Treated Heat-Polymerized Acrylic Resin after Repair with Aluminum Oxide-Reinforced Autopolymerizing Acrylic Resin.

Background: A fracture of denture base often occurs through a fatigue mechanism, which over a period of time leads to the formation of small cracks, resulting in fracture.

Aim And Objective: To evaluate the flexural strength of repaired heat-polymerized acrylic resin, with different percentage of aluminum oxide (AlO) added to the repair resin and effect of two different surface treatments on the flexural strength of repaired heat-polymerized acrylic resin and also to evaluate quantification of filler particles using scanning electron microscopy.

Materials And Methodology: Fifty specimens of heat-polymerized acrylic resin were prepared according to the American Dental Association specification no.
