CHARACTERISTICS OF EMG-ACTIVITY OF MASTICATORY MUSCLES IN FUNCTIONAL TREATMENT OF PATIENTS AT RETENTION STAGE.

UNLABELLED: The aim of the research was to study changes of EMG-activity of masticatory muscles after functional therapy at the retention stage after active orthodontic treatment.

MATERIAL AND

METHODS

The study included 55 people at the beginning of the retention stage after active orthodontic treatment. Patients of the study group were carried out functional therapy using proposed appliance during 3 month. The control group used the standard retention method. Clinical examination and EMG of masticatory muscles was performed to all patients at the beginning of the retention and in tree months.

RESULTS AND

CONCLUSION

In 3 month of functional correction EMG-activity of the masticatory muscles significantly decreased and became synchronous and symmetrical in patients of the study group, that proved the effectiveness of the method of functional therapy at the beginning of retention stage after active orthodontic treatment.
