[摘要]目前,下颌前突主要采用正畸正颌联合治疗,为了达到患者满意的效果,常规治疗模式的主要过程需要先进行牙齿矫正治疗,再用外科方式矫正颌骨畸形,术后再进行牙齿矫正治疗。与之相比,以外科手术治疗颌骨畸形作为治疗的第一步,再通過牙齿矫正将咬牙合关系调整到最佳状态,是一种治疗下颌前突畸形新的方式,表现出了治疗时间的缩短并能较快地改善面部美观,对于成人的社交工作活动方面是有利的。现就其形成、治疗步骤及优缺点综述如下。

Abstract: At present,mandibular protrusion is mainly treated by orthodontic-orthognathic surgery. In order to achieve satisfactory results, the main process of conventional orthognathic surgery treatment mode is: Advanced orthodontic treatment, surgical correction of jaw deformity, and postoperative orthodontic treatment. Compared with conventional treatment mode, Surgery-First Approach mode uses surgical treatment of jaw deformity as the first step of treatment, then adjusts the occlusion relation to the best state by orthodontics, which has advantageous for adult social work activities by is shorting the treatment time and improving facial appearance quickly.We will discuss its formation,treatment steps, advantages and disadvantages in this paper.

下颌前突是由于颌骨生长发育出现异常,口内表现为牙合关系及口腔颌面系统功能异常,口外表现为面型异常、美观受损,可引起反牙合,对刃牙合[1]。对不再生长发育、并具有下颌骨骨性前突畸形的病例,实施手术前牙齿矫正、正颌手术及手术后牙齿矫正在内的正颌治疗,称为常规治疗方式(conventionalorthognathic surgery ,COS),达到了改善美观、恢复牙齿及颌面部功能、治疗效果被接受的目的[2-3]。不过,随着时代的进步,社会节奏的变快,其过程复杂疗程过长,造成患者的时间难度,一定程度上有悖于成年患者社交的需求。
近年来,“手术优先”模式的应用,优化了治疗程序缩短了疗程,能够较快地使患者具有满意的系统功能和美学形态等优点[4],被临床医生和患者所接受,大大缓解了患者对于时间方面的顾虑。
