- Abstract
Introduction and objectives: The relationship between form and function of the stomatographic system has been studied by several researchers and it is still not clear, whether a genetically determined facial morphology decides the strength of masticatory muscles, or whether a strong musculature influences the form of the face. The present study was done to relate muscle activity with various malocclusions. Materials and methods: Sixty samples of younger age group were divided according to Angle classification. The electromyography (EMG) activity of masseter and temporalis and the maximum bite force (MBF) at intercuspal (molar) and anterior bite position (incisors) have been studied for different malocclusion groups. Influence of various independent variables like gender, overjet and overbite of the subjects on the bite force was also checked. Results: MBF at intercuspal position (molar) and anterior bite position (incisal) were not significantly different between normal, Class I, Class II Division 1 and Class III malocclusion groups. Conclusion: It was concluded that Class III malocclusion subjects showed the highest masseter and anterior temporalis postural rest activity and Class II Division I malocclusion showed the least anterior temporalis activity at both the intercuspal and interincisal positions during maximum voluntary biting.
