骨皮质切开术及其辅助正畸牙齿垂直向控制研究进展

Research progress of vertical control of teeth by corticotomy in the orthodontic clinic

成人患者多伴有牙周、关节等问题,正畸治疗机制复杂、疗程较长,患者不仅对疗效要求高,对正畸治疗的疗程也颇为关注。骨皮质切开术,通过切开牙齿周围的骨皮质,辅助加速牙齿移动,缩短疗程,为成人正畸提供了一种新的治疗理念与思路。术中辅助植骨,可减轻治疗风险,同时可改善患者的牙周状况。骨皮质切开术日趋成熟,作为一种牙周辅助快速正畸技术在国外已应用于临床。本文将对骨皮质切开术在正畸牙齿垂直向控制中的临床应用、发展、优缺点以及一般临床程序等做一综述。

Periodontitis and temporomandibular joint disease are quite common among adult patients. The treatment mechanism for adult patients is relatively more complicated, leading to a long therapeutic course, which makes adult patients demand more towards the safety and period of the orthodontic treatment. One choice for accelerating tooth movement and reducing treatment time is ＂corticotomy＂, which takes effect by cuts limited to cortical plate surrounding certain teeth, providing a new idea and train of thought for the vertical control in adult orthodontic treatment. Intraoperative auxiliary bone graft reduces the treatment risks and improves the patient＇s periodontium at the same time during the corticotomy. With the development of the technique, it has been widely used clinically in lots of foreign countries. This paper reviewed the development, clinical operation and application, merits and drawbacks and also the prospect of the cortieotomv technique durinz vertical control in the orthodontic treatment.
