This article describes an orthodontic mechanical variation to reduce prominence of the palatal cusp of the upper second molar and to correct buccal crossbites in the molar area. By using a modified transpalatal arch with a soldered spur, a button bonded to the palatal surface of the second molar, and an elastic chain intrusion of the palatal cusp with control of buccal root torque is accomplished. The palatal intrusion technique provides a simple and very efficient approach to correct upper second molar position.
本文描述了一种正畸机械变异方法,用于减少上颌第二磨牙腭尖的突出度,并矫正磨牙区的颊侧反牙合。通过使用带有焊接刺的改良腭弓、粘结在第二磨牙腭面的纽扣以及弹性链,实现了腭尖的压低并控制颊侧牙根转矩。腭侧压低技术为矫正上颌第二磨牙位置提供了一种简单且非常有效的方法。
