To evaluate the muscle response in order to determine the mechanism of neuromuscular adaptations with Forsus Fatigue Resistant Device which has greater elasticity and flexibility; allows greater range of movement of mandible; is available in prefabricated assembly of springs, tubes and rods and is a simple, effective and reliable corrective appliance that benefits not only growing patients but also malocclusions that previously required extractions, headgears and surgery.
Bilateral EMG activity from anterior temporalis and masseter muscles was monitored longitudinally on 10 young growing females with Class II Division 1 malocclusion to determine changes in postural, swallowing, and maximal voluntary clenching over an observation period of 6 months.
There was a significant decrease in the muscle activity at one month after Forsus Fatigue Resistant Device insertion during swallowing of saliva and maximal voluntary clenching which gradually returned to pre treatment levels at the end of six months.
This study suggests that Forsus Fatigue Resistant Device should be given for at least six months to allow for adequate neuromuscular adaptations to occur for long-term stability of the result.
评估肌肉反应，以确定使用具有更大弹性和灵活性的Forsus抗疲劳矫治器时神经肌肉适应的机制；该矫治器可使下颌有更大的活动范围；采用弹簧、管子和杆的预制组件，是一种简单、有效且可靠的矫正器具，不仅有益于生长发育期的患者，也适用于先前需要拔牙、佩戴头帽和进行手术的错牙合畸形患者。
对10名患有安氏II类1分类错牙合畸形的年轻生长发育期女性，纵向监测颞肌前束和咬肌的双侧肌电图活动，以确定在6个月的观察期内姿势、吞咽和最大自主紧咬时的变化。
在插入Forsus抗疲劳矫治器后1个月，唾液吞咽和最大自主紧咬时的肌肉活动显著降低，在6个月末逐渐恢复到治疗前水平。
本研究表明，Forsus抗疲劳矫治器应佩戴至少6个月，以便有足够的神经肌肉适应发生，从而使结果获得长期稳定性。
