文题释义:
三维扫描技术:是一种显示物体表面的三维形态的立体测量技术,能够采集提取物体表面的三维几何形状,通过软件进行建模,从而得到具有物体表面三维数据的数字化三维模型。
下颌前突:是下颌骨过度向前向下生长,从而引起咬合关系错乱并致面下部错牙合畸形的一种牙颌面畸形。临床上常表现为面下1/3向前向下突出,下唇及颏部位置靠前,后牙呈安氏Ⅲ类错牙合,前牙呈反牙合或对刃牙合。

摘要
背景:
下颌前突畸形经典的正颌外科修复方案包括术前的头影测量,取模,面弓转移,模型外科,制做牙合板等过程,其流程繁琐复杂且往往容易存在偏差,修复后的难以预估更是一直困扰医生与患者沟通时的一大难题。
目的:对近年来数字化三维扫描技术在下颌前突畸形临床诊治中的应用现状进行综述,阐述其原理、应用及优缺点,为临床使用提供参考。
方法:于2015年9月以“三维扫描,骨性Ⅲ类,正颌,下颌前突”为中文关键词,以“three-dimensional scanning,classⅢ,orthognathic,mandibular prognathism”为英文关键词,采用计算机检索万方医学网和PubMed数据库,筛选有关三维扫描技术在下颌前突畸形诊治中的应用文章48篇进行分析。
结果与结论:三维扫描技术在对下颌前突畸形患者修复前的诊治具有较传统测量技术所不具备的高精确度、耗时短的特点,并能直接实时采集捕捉物体的三维几何形状,进行体表器官解剖形态建模,采集、测量体表生物信息数据,为修复后的评估以及随访提供了可靠的监测方法。与CT相比,三维扫描技术无法显示扫描物的内部结构,无法分离软硬组织层次,因而在临床使用中需根据数据需求合理选用。

Abstract:

BACKGROUND: A classical orthognathic scheme for mandibular prognathism includes preoperative cephalometric analysis, acquiring modulus, facebow transfer, model surgery, making occlusion plate. This process is cumbersome, complex, and prone to have bias. Moreover, orthognathic effects are difficult to be predicted, which is a major difficulty in doctor-patient communication.
OBJECTIVE: To summarize and analyze the use of three-dimensional scanning techniques in the treatment and diagnosis of mandibular prognathism, including principle, application and relative merits, thus providing reference for applying to the clinic.
METHODS: Papers addressing the use of three-dimensional scanning techniques in the diagnosis and treatment of mandibular prognathism were retrieved by computer in Wanfang and PubMed databases with the key words of “three-dimensional scanning, class III, orthognathic, mandibular prognathism” in Chinese and English, respectively. A total of 48 papers were included for review.
RESULTS AND CONCLUSION: Compared with the traditional technology, the three-dimensional scanning technology has high accuracy and efficiency in the diagnosis and treatment of mandibular prognathism, and can directly capture the 3D geometry of objects for modeling, collection and measurement of biological data, which provides a reliable monitoring method for postoperative assessment and follow-up. Compared with the CT, the three-dimensional scanning technology cannot show the internal structure and separate hard and soft tissues, which should be reasonably chosen according to practical data.
