Influence of occlusal schemes on the muscular activity of edentulous patients

Abstract An investigation utilizing different occlusal schemes on the same denture base was conducted to test the variance in muscle activity during mastication. Results indicate that the anatomic occlusion required the least activity from the closing muscles for all test foods. The reverse curve occlusal scheme required the greatest closing muscle activity during the chewing of carrots and peanuts. Thus, the form of posterior occlusion is an important factor in the amount of muscle activity during mastication.
