By means of computer-based statistical methods, several types of Class II malocclusion have been discovered with defining horizontal and vertical characteristics. Of the six horizontal types, four are severe syndromes, one is a loose, ill-defined grouping of cases with mild skeletal features, and one has only the dental features of Class II. Five vertical types associates with Class II were also revealed, although each vertical is not associated with all horizontal types. A simplified simulation of the computerized procedures has been developed for routine use in clinical practice.
通过基于计算机的统计方法，已发现了几种具有明确水平和垂直特征的安氏II类错牙合。在六种水平类型中，四种是严重综合征，一种是具有轻度骨骼特征的病例的松散、不明确分组，还有一种仅具有安氏II类的牙齿特征。还发现了与安氏II类相关的五种垂直类型，尽管每种垂直类型并非与所有水平类型相关。已开发出一种简化的计算机程序模拟方法，以便在临床实践中常规使用。
