Neuromuscular adaptations with flexible fixed functional appliance – a 2-year follow-up study

Aim To evaluate long-term neuromuscular adaptation with the flexible fixed functional appliance. Patients and methods Electromyography (EMG) was performed on 15 young, growing females with Class II Division 1 malocclusion treated with a flexible fixed functional appliance. Bilateral EMG activity fro...

Description
Summary:Aim To evaluate long-term neuromuscular adaptation with the flexible fixed functional appliance. Patients and methods Electromyography (EMG) was performed on 15 young, growing females with Class II Division 1 malocclusion treated with a flexible fixed functional appliance. Bilateral EMG activity from the anterior temporalis and masseter muscles was monitored longitudinally to determine changes in posture, swallowing, and maximum voluntary clenching during a 24-month observation period. Results There was a significant decrease in EMG activity during saliva swallowing (p
