摘要

前牙開咬的主要特徵是上下顎前牙區缺乏垂直覆蓋(overbite)，臨床上前牙開咬的治療處置及長期預後一直是困擾矯正醫師的難題。前牙開咬可以分為齒性開咬及骨性開咬。在治療方面，齒性開咬通常可以經由單純的齒列矯正而改善；成人骨性前牙開咬則可能需要合併齒列矯正及正顎手術。近年來，迷你植體錨定的發展已為傳統矯正治療帶來許多突破，利用植體錨定進行臼齒內縮移動而促成前牙開咬閉合便是其中一例。本篇文獻回顧將依據患者生長發育的不同狀況，探討骨性前牙開咬的診斷及各種非手術性治療。

Anterior open bite is defined as the lack of vertical overlap of the anterior teeth in centric occlusion. There is no question that one of the most difficult malocclusions to treat and maintain in orthodontics is the anterior open bite. Open bite can be divided into dental open bite and skeletal open bite. Dental open bites are generally more responsive to treatment with orthodontics alone. Skeletal open bite is a more complicated malocclusion characterized by overgrowth of the posterior dentoalveolar heights. Inhibition of vertical facial growth is often advocated in the treatment for the growing patients with skeletal open bites. However, surgical impaction of the maxilla is often required for the counterclockwise rotation of mandible in adult patients with severe skeletal open bite. Mini-implants anchorage has recently been popular and reported to be effective in achieving different types of tooth movements, including molar intrusion. Thus skeletal anterior open bite could be corrected by molar intrusion in a simpler and less invasive way compared to orthognathic surgery. In this article, diagnosis of skeletal anterior open bite and the principles of non-surgical treatment are reviewed and discussed.
