Abstract

The purpose of this study was to evaluate the effect of different occlusal concepts which are bilateral balanced occlusion, canine guided occlusion on masticatory efficiency, in implant supported mandibular over denture wearers.
Material and methods: ten completely edentulous patients were selected for this study, aged 50 to 60 years old. All patients free from any systematic dieses. The patients were divided into three groups according to the treatment protocol; {GI} All patients wore denture with intra oral adjustment, {GII} five patients wore denture with bilateral balanced occlusion and {GIII} five patients wore denture with canine guided occlusion. All patients were submitted to masticatory efficiency test, after one month by using different textures of foods. The recordings data were analyzed using ANOVA. This was followed by Tukey’s post hoc test using LSD test. P< 0.05 was considered statistically significant. Results: with soft food, there was non-significant difference between the three groups, while with hard food; the greatest mean was recorded in occlusion after oral adjustment, whereas the lowest mean was recorded in bilateral balanced occlusion. Conclusion both bilateral balanced occlusion and canine guidance occlusion can be used successfully in implant supported overdentures without affecting masticatory function.
