Abstract

Aim: This study aimed to investigate the correlation between chewing efficiency and muscle kinetics using balanced occlusion and group function occlusion. Methodology 20 edentulous patients were selected and given a complete denture with balanced occlusion( Group A) for one month, and then they were recalled the first denture collected and a new denture using group function ( Group B) was given for one month. Chewing efficiency was measured using the standardized chewing test units (SCT) and muscle kinetics was measured using Electromygraphy (EMG). After both follow up periods, patients were asked about their satisfaction with both groups using the visual analog system (VAS). Results In Balanced occlusion there was a negative correlation of -0.594 between chewing efficiency and muscle kinetics, which means they are directly proportion to each other.. However, in group function occlusion; there was a positive correlation of 0.463, which means are inversely proportion. On the VAS scale patient satisfaction recorded 9 (highly satisfied) with the group A and 5 (Neutral) with group B. Conclusions It can be concluded from this study that the balanced occlusion scheme allowed better chewing efficiency, with lower muscle kinetics, and higher patients’ satisfaction.

Summary

Introduction

The basic fundamentals of life for all living organisms are water and food. In chewing of food and deglutition we need teeth to perform this basic physiologic process. Patients’ satisfaction with complete denture usually doesn’t meet with previous expectations.[1, 2] As the complete denture is a removable prosthesis, gaining entirely its support from soft mucosa so, movement is expected. This results in inefficient chewing of food. The patients’ individual measures should be close to these averages in order for the denture to be stable Balanced occlusion is another scheme; balanced Occlusion is defined as the bilateral, simultaneous, anterior, and posterior occlusal contact of teeth in centric and eccentric positions. Is the type of occlusion scheme used directly related to the chewing efficiency, the muscle kinetics and patient satisfaction? Is the type of occlusion scheme used directly related to the chewing efficiency, the muscle kinetics and patient satisfaction? And what is considered optimum, to make high or low muscle contraction to cut down food?
