Clinical Study on the Effect of the Single Crown on Segmental Chewing

Abstract

Chewing is closely related to occlusion, and occlusion of a specific tooth affects segmental chewing. Therefore, analysis of chewing is supposed to have diagnostic value for assessing occlusion. However, the difference in segmental chewing among various teeth is unclear. Comparison in segmental chewing between before restoration and after restoration was performed in 55 patients who were treated by a single premolar or molar restoration.
The results are summarized as follows:
1. Chewing pattern and chewing speed pattern
1) Premolar restoration had little effect on chewing.
2) First molar restoration revealed a tendency to improve chewing, and second molar restoration demonstrated a tendency to worsen it.
2. Chewing rhythm
Molar restoration showed a tendency to shorten the duration of the occlusal phase.
