Purpose: The purpose of this study was to compare the effect of two different complete denture occlusal schemes on the occlusion and disocclusion times.
Material and methods: Eight completely edentulous male patients were selected, for each patient, two conventional complete dentures were constructed, one of them following the lingualized concept of occlusion and the other following monoplane concept of occlusion using the conventional technique of denture construction. Computerized occlusal analysis was conducted using the T-Scan system. Occlusal parameters (OT and DT) were recorded for both dentures for each patient.
Results: The results showed that occlusion time, right and left disocclusion time are higher in monoplane occlusal scheme dentures than lingualized occlusal scheme dentures and the difference was statistically insignificant.
Conclusion: Within the limits of this study no significant difference in occlusion and disocclusion time between lingualized and monoplane occlusal sheme complete dentures were found.
