Abstract
This study was planned to evaluate to what extent providing complete denture wearer with three different occlusal concepts (balanced occlusion, canine guidance and monoplane occlusion concepts) would beneficially or adversely affect masticatory performance and masseter muscle activity with acrylic maxillary denture base deformation. from results of this study it can be concluded that; 1.Varying occlusion concept for complete denture prosthesis apparently had no effect on patient’s own masticatory performance, but it appears as patient habitual maneuver. 2.Dentures provided with canine protected occlusion concept demonstrated less adverse muscle activity than others, and it appeared recommended for patients having poor neuromuscular co-ordination.3.Monoplane occlusion concept demonstrated less denture base deformation than balanced and canine protected occlusion concepts and being recommended for debilitated alveolar ridges.
