This study was initiated to compare electromyographically the activity of the masseter and temporal muscles during the early retentional period in orthodontic patients. Electromyographic recordings were taken at the following times: (1) before typical edgewise appliance was removed, (2) at time of retainer insertion, (3) after eight to twelve weeks of retainer wearing, and (4) one day following occlusal equilibration. Electromyograms from the orthodontic group of subjects were compared with electromyograms from a group of subjects with normal occlusion, and a group of subjects with untreated Class II, Division 1 malocclusions. There was a total of thirteen subjects studied: five …
