高角病例和低角病例的诊断和形成机制High angle and low angle cases diagnosis and form
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。Referred to article as high-angle and low angle, should not be confuse with the mandibular plane angle, if it is high, called high angle case, and if small than low angle case. Because the mandibular angle and mandibular margin changes with growth,so simple mandibular plane angle as the diagnostic criteria may mask the true mandibular rotation and direction of the vertical growth.The correct diagnosis should be combined with other indicators5
