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.
