Using the Treil 14 points cephalometric model orthodontists can prepare a complete cranio-facial anatomic assessment at three analytic levels: the framework or envelope, the basal bone and the alveolo-dental arcade. The assessment of border-line surgical antero-posterior dysmorphosis can elucidate interesting depictions of asymmetries, their relation to other malformities, and their genesis. Asymmetry arises from over-growth of one side of the face in all three dimensions of space even if, clinically, it often appears that one dimension is predominately affected. The ortho-morphic cases of Angle Class I present a little right excess or "natural" asymmetry. The Class III cases present a severe excess on the right side, while the Class II cases present an excess on the left side comparing with reference sample.
使用特雷尔14点头颅测量模型，正畸医生可以在三个分析层面进行完整的颅面解剖评估：框架或包膜、基底骨和牙槽牙弓。对临界手术前后畸形的评估可以阐明不对称的有趣描述、它们与其他畸形的关系及其成因。不对称是由于面部一侧在空间的所有三个维度上过度生长所致，即使在临床上，通常看起来只有一个维度受到主要影响。安氏I类的正形病例存在轻微的右侧过度或“自然”不对称。与参考样本相比，III类病例右侧严重过度，而II类病例左侧过度。
