根据上颌骨、下颌骨、上颌骨牙槽骨、下颌骨牙槽骨的位置和垂直方向的发育情况，对骨性III类错牙合进行分类。这种形态学的方法是简单和有用的临床使用，但它是不够的，允许理解的病理生理dysmorphoses.The作者假设，有不同的模式的相互关系的骨骼组件的病理平衡的骨骼III类错牙合。本研究的目的有三个方面：（1）将骨性III类错牙合分为能够显示畸形结构特征的亚组，（2）在病因-致病基础上分析每个亚组的颅面结构，（3）将模式表征和可视化为原型。在这项研究中使用的材料是106个未经治疗的骨性III类错牙合成人的头颅侧位X线片，这是分析与修改Delaire的分析。获得每个受试者的线性和角度测量值，并使用聚类分析进行分组。在结果中，七组被确定并作为原型，这可以显示骨骼结构的病因病理。本研究中提出的分类和描述被认为是生物学的，有助于理解骨性III类错牙合和治疗计划。
Skeletal Class III malocclusion has been classified by the position of the maxilla, the mandible, the maxillary alveolus, the mandibular alveolus and vertical development. This morphologic approach is simple and useful for clinical use, but it is insufficient to permit understanding of the pathophysiology of dysmorphoses.The authors hypothesized that there were different patterns of mutual relation of the skeletal components contributed to pathologic equilibrium of skeletal Class III malocclusion. The purpose of this study is 3-fold; (1) to classify skeletal Class III malocclusion in subgroups that can show the architectural characteristics of the deformity, (2) to analyze the craniofacial architecture of each subgroup on etio-pathogenic basis, and (3) to characterize and visualize the pattern as a prototype. Materials used in this study were lateral cephalograms of 106 untreated skeletal Class III malocclusion adults, which were analyzed with modified Delaire's analysis. Linear and angular measurements of each subject were obtained and cluster analysis was used for grouping. In the results, seven groups were identified and presented as prototypes, which could show the etio-pathology of the skeletal architecture. The classification and description presented in this study is thought to be biologic and helpful in the understanding of skeletal Class III malocclusion and treatment planning.
