Abstract

ABSTRACT The purpose of this study was to evaluate the masticatory efficiency of two occlusal schemes; canine guidance occlusion and bilateral balanced occlusion in thermoplastic complete dentures. Ten male completely edentulous patients whose ages ranged from 55 to 70 years were selected. The selected patients were free from any temporomandibular joint disease in order not to affect their masticatory efficiency. Half of the selected patients received a complete denture with canine guidance occlusal scheme and the other half of the patients received a complete denture with bilateral balanced occlusal scheme. One month was left as an adaptation period then the masticatory efficiency of the first occlusal scheme was tested, then the occlusal scheme was changed to the other one. After another one month, the masticatory efficiency of the second occlusal scheme was tested. The data were collected, tabulated and analyzed by using Paired-sample t-test. The results of this study showed that there was no significant difference between the canine guidance occlusal scheme and the bilateral balanced occlusal scheme in the number of strokes, the number of swallows and the time (in seconds) elapsed during chewing all test foods (banana, peanut and carrot). It was concluded that both bilateral balanced occlusion and canine guidance occlusion can be used successfully in thermoplastic complete dentures without affecting the masticatory efficiency.
