上颌前突患者畸形的因素可存在于上颌骨骨体或牙槽突部。并且由于牙齿与牙槽的补偿作用,往往伴有下颌前牙的唇舌向倾斜和牙槽突过长。因此,为了使患者重获正常的功能与外形,术前设计不仅十分重要,而且常常面临一些相当复杂的问题。作者等鉴于临床工作的需要,并根据我院三年来的临床实践,对上颌前突畸形进行了归纳和分类。本文将以手术设计为中心发表雏见并列举典型病案进行分析讨论。 Patients with maxillary protrusion may have deformities in the maxillary bone or alveolar process. And due to the role of teeth and alveolar compensation, often accompanied by mandibular anterior lingual tongue tilt and alveolar over. Therefore, in order to regain the normal function and appearance of patients, preoperative design is not only very important, but also often faces some rather complicated problems. In view of the need of clinical work and according to the clinical practice in our hospital for three years, the author summarized and classified maxillary protrusion deformity. This article will focus on the design of surgery published preoccupation and enumeration of typical cases for analysis and discussion.
