颏部形态学方面的变化,常受三个空间平面的影响,即后前平面、垂直平面和横向平面。每一种咬合类型可有典型的面容,颏部形态在不同个体,甚至在同样牙面畸形的基本类型上也可有很大变化。因此对发育性颏短小畸形采用外科整复时,必须全面考虑,周密计划,方可使整复后能达到最理想的美容和功能效果。颏成形术是各种外科正畸术中最常采用的一种附加手术,对此国内尚未见有专文报道。本文主要介绍经我们临床采用,而且行之有效的整复方法,并就其适应证、手术方法及操作要点,结合临床体会加以讨论。
Changes in chin morphology are often affected by three spatial planes, the posterior plane, the vertical plane and the transverse plane. Each occlusal type can have a typical face, chin shape in different individuals, even in the same basic types of tooth deformities can also have great changes. Therefore, the development of short mental deformity surgical reconstructive surgery, we must fully consider the careful planning, before the restoration can achieve the best cosmetic and functional effects. Genital plasty is the most commonly used additional surgery in various surgical orthodontics, and has not yet been reported in the country. This article describes the clinical adoption by us, but also effective restoration methods, and its indications, surgical methods and operational points, combined with clinical experience to be discussed.
