Effect of occlusion pattern on masticatory efficiency

To study the effect of occlusion pattern on masticatory efficiency, 10 edentulous subjects were selected. Upper and lower complete dentures were constructed with protrusive balancing ramps to establish protrusive balance. Masticatory efficiency was tested by chewing hard and soft type of foods. The time needed to masticate both types of food was recorded. The balancing ramps were ground and masticatory efficiency was tested again. The recorded time values were calculated and statistically analyzed

Effect of increasing weight of lower complete denture on physiologic rest position of the mandible

To study the effect of increasing weight of the lower denture on the physiologic rest position of the m and ible, 30 complete denture wearers complaining of instability of their lower dentures were selected. The physiologic rest position was recorded and the weight of the lower denture was increased 50% for one week and the rest position was recorded. After one week, the weight was increased 100% of its original weight and the physiologic rest position was recorded. The collected data were tabulated and statistically analyzed
