高角和低角病例的诊断、临床特征及 正畸治疗特点

• 由于以往的诊断是以安氏 分类为主, 正畸医生常常
只注意到矢状向错牙合而 忽略了垂直向不调。

Previous diagnosis was based on Angle's classification so orthodontists often
only noticed the sagittal malocclusion while ignoring
the vertical dimension.

• 近年来, 学者们逐渐认识 到垂直面型在错畸形诊断 和治疗中的重要性: 它不 仅为颅面复合体的生长方 向提供了线索, 而且直接 影响治疗的成功与否。

In recent years, scholars have come to realize the importance of the vertical dimensions in the
diagnosis and treatment of malocclusion it not only
provides clues to the direction of growth of the craniofacial complex, but also directly affects the success of treatment.

垂直向异常有高角和低角两种类型, 在Ⅲ类

安氏错牙合中约有50%左右的患者存在不同程度

的垂直向异常。

• Vertical anomaly are of two types of high-angle and low angle, about 50%of patients with angle class III malocclusion have varying degrees of abnormal vertical dimension

• 文献中用来描述垂直向异常的说法很多,常用的有开张面 型( hyperdivergent ) 、向后旋转型( backward rotation ) 、 垂直生长型(vertical type) 、长面型( dolichocephalic ) 、 高角型( high -angle face ) , 均指垂直向异常以发育过度 ( vertical excessive ) 为主, 而聚合面型( hypodivergent ) 、 向前旋转型( forward rotation) 、水平生长型( horizontal type) 、短面型( brachypechalic) 、低角型( low -angle face) 则是指垂直发育不足( vertical deficiency ) 。
• 由于诊断标准和侧重点不同, 从严格意义上讲, 这些概念之 间是有差异的, 但在临床中描述垂直面型时经常通用。 Diagnostic criteria and a different focus, in the strict sense, these concepts there is a difference, but often common in the clinical description of vertical type.

本文中统称为高角和低角, 但不能误解为下

颌平面角大者即为高角型、小者即为低角型, 这

是因为下颌角和下颌下缘在生长改建过程中变

化较大, 所以单纯以下颌平面角作为诊断标准可

能掩盖了下颌真实的旋转方向,对垂直面型的正

确诊断还应结合其他指标。
