(6)肌功能的训练和矫治:当咀呷诸肌、唇肌、舌肌等功能不平衡时,则可引起牙、牙弓以及颌骨的异常发育。由于过分使用某种肌肉,或长期不正常姿式等,都会引起畸形,因此,保持肌肉的功能平衡是促进组织正常生长发育的重要因素之一。肌肉功能训练,是使肌肉在生理范围内,达到最大限度的收缩,因此肌肉收缩要缓慢而持续,有规律地进行,休息时间和收缩时间相等,反复多次,到肌肉疲劳时为止。这种方法可以单独进行,也可以配合其他矫治法进行。
(6) Muscle function training and correction: When the Zhuo Zhu muscle, lip muscle, tongue muscle and other functions are not balanced, it can cause teeth, dental arch and jaw abnormalities. Due to excessive use of a muscle, or long-term abnormal posture, can cause deformity, therefore, to maintain the balance of muscle function is to promote normal tissue growth and development of one of the important factors. Muscle function training, is to make the muscles in the physiological range, to achieve the maximum contraction, so muscle contraction to slow and sustained, regularly, rest and contraction time equal, repeated many times until muscle fatigue so far. This method can be carried out alone, can also be used with other correction method.
