Research Abstract

This study evaluated the effect of the location of glass-fiber-reinforced composites (FRC) reinforcement on the flexural load of a maxillaryacrylic resin complete denture. Maxillary acrylic resin complete dentures strengthenedwith FRC reinforcement were tested. Reinforcement was embedded in the denture base resinand placed 1) under the ridge lap region; 2) in the anterior region; 3) in the middleregion or 4) in the anterior and posterior regions. The flexural load of the reinforcedmaxillary denture specimens was tested. All of the reinforced dentures with FRCreinforcement had a higher flexural load than the denture without reinforcement and werenot significantly different from each other.
