The diagnosis, treatment planning, and design of mechanics for the asymmetric patient requires the differentiation between problems of dental and skeletal origin. Although much information can be gleaned from a cephalometric analysis, the clinical examination and study models offer important clues in establishing the diagnosis of skeletal discrepancy. Abnormal and asymmetric axial inclinations can either produce a dental asymmetry or, if compensatory in nature, may mask an underlying skeletal problem. The role of axial inclination in diagnosis is applied to the following situations: subdivision cases, unilateral crossbites, midline discrepancies, arch form deviations, and frontal cants to the occlusal plane. The management of axial inclination asymmetries depends on the treatment plan. Nonextraction patients may require maintenance of asymmetric compensatory axial inclinations. Surgical and extraction patients can be treated to a more ideal symmetry.
对于不对称患者的诊断、治疗计划制定及力学设计，需要区分牙齿源性问题和骨骼源性问题。尽管通过头影测量分析可以获取很多信息，但临床检查和研究模型在确立骨骼差异的诊断方面提供了重要线索。异常和不对称的轴倾度可能会导致牙齿不对称，或者如果是代偿性的，则可能掩盖潜在的骨骼问题。轴倾度在诊断中的作用适用于以下情况：分类病例、单侧反合、中线差异、牙弓形态偏差以及咬合平面的 frontal cants（此处可能有误，暂按原文）。轴倾度不对称的处理取决于治疗计划。不拔牙患者可能需要维持不对称的代偿性轴倾度。手术和拔牙患者可以治疗至更理想的对称状态。
