本文以TN矫治器为基础，寻找出一个相当于磨牙阻抗中心的着力点。它将活动和固定矫治技术结合在一起，最大限度地增加支抗牙的数目，充分利用颌内交互支抗，并使单纯以后牙为支抗的时间减少。通过这几方面的协同作用来增强后牙的支抗作用。作者只应用颌内支抗，经93例临床应用．支抗磨牙平均前移0．58mm，无一例发展到由于支抗磨牙失控而造成关系破坏。
This article based on the TN appliance, to find a point equivalent to the grinding teeth impedance center. It combines activity with fixed orthodontic techniques to maximize the number of supporting teeth, take full advantage of the intercostals in the jaw, and reduce the time it takes for the simplex to support the teeth. Through these synergies to enhance the role of the support of the posterior teeth. The author only uses the jaw internal fixation, and has clinical application in 93 cases. An average of 0.58 mm of anvil molar advance, no one developed to the relationship between the destruction caused by the loss of control molar.
