Abstract:
Electromyography of masticatory muscles has proved useful for the functional study of occlusal dysfunctions. We employed this technique to study the activity of masseter and temporal muscles of 6 subjects with Class II division 2 malocclusion and 7 subjects with Class III malocclusion. Significant differences of masticatory muscles activity during mastication and swallowing were observed between the two groups. We hypothesize that the change of the activity of masticatory muscles might influence the clinical presentation of malocclusion.
