This article describes the Active Vertical Corrector (AVC), which is a simple removable or fixed orthodontic appliance that intrudes the posterior teeth in both the maxilla and mandible by reciprocal forces. By the use of effective posterior intrusion of teeth, the mandible is allowed to rotate in upward and forward directions. The uniqueness of this appliance is that it allows the clinician to correct anterior open bite problems by actually reducing anterior facial height. This treatment approaches the problem at its cause (overeruption of posterior teeth) and provides better facial balance and esthetics than most conventional orthodontic treatment procedures. Problems formerly thought to require orthognathic surgery can now be treated successfully with the AVC.
本文介绍了主动垂直矫治器（AVC），它是一种简单的可摘或固定正畸矫治器，通过相互作用力使上颌和下颌的后牙压低。通过有效地压低后牙，可使下颌向上和向前旋转。该矫治器的独特之处在于，它能让临床医生通过实际减小前面部高度来矫治前牙开颌问题。这种治疗方法针对问题的根源（后牙过度萌出），比大多数传统正畸治疗方法能提供更好的面部平衡和美观效果。以前认为需要正颌手术治疗的问题现在使用AVC也能成功治疗。
