种植体支抗辅助牙列整体远移的疗效及长期稳定性的研究进展

Advances in studies on distal molar movement with temporary anchorage devices

牙列拥挤和牙齿前突常是正畸患者就诊的主要原因，对于严重拥挤或前突的患者，临床常行减数前磨牙矫治。但对轻度拥挤或前突的患者，临床可采用种植体支抗辅助远移牙列的方案。本文对种植体支抗辅助远移牙列的矫治效果、影响因素和疗效稳定性等方面进行综述。

Crowding and protrusion of the dentition are often the chief complaint of orthodontic patients. For patients with severe crowding or protrusion, orthodontist often improve their profile with premolar extraction treatment. However, for patients with mild crowding and protrusion, orthodontist usually achieve treatment objective using distal molar movement with temporary anchorage devices （TAD）. The present article reviewed the advances in the use of TAD in total arch distalization, including therapeutic effect measured in three-dimensions, factors that affected distal movement and the stability of curative effect.
