Abstrakt:	Background: The complete denture teeth arrangement that gives maximum denture stability, comfort, esthetics, and function have been studied since several years. Many occlusal schemes have been advised in which the lingualized occlusion, balanced occlusion, and monoplane occlusion are advocated most popularly. The purpose of this study was to compare the pressure values on the supporting tissue using three diff erent posterior occlusal schemes: Balanced occlusion, lingualized occlusion, and monoplane occlusion in simulated dentures. Materials and Methods: The simulators used in this study, composed of the maxillary, and mandibular clear heat cure acrylic resin edentulous models. Pressures on the supporting structure under the complete denture were measured using eight strain gauges placed on the model surface on the buccal and lingual slopes of the ridges on the molar and pre-molar region. Pressure on the supporting structure was measured and signals from the sensors were amplifi ed and recorded by the multi-channel electronic strain indicator. Results: The mean pressure which was obtained at each measurement point was compared by one-way ANOVA test. Conclusion: Overall monoplane occlusion had lesser pressure values compared to completely balanced and lingualized occlusal scheme. Lingualized occlusal scheme was found to transfer stresses from working side to non-working side to stabilize the mandibular denture.
