The findings of this experiment revealed important associations among dental and skeletal parameters in differing degrees of mandibular rotation. The structural elements of the craniofacial complex vary in size, morphologic pattern and their spatial relationship dictate the relationship of the dental arches. The results of these comparisons support the assumption that variations in the mandibular plane angle are also accompanied by a significant difference in the craniofacial relations. 1. The degree of mandibular rotation is not significantly associated with the dental classification in any group or the total sample. 2. Significant correlations were determined for the dental classification and the horizontal skeletal measurements of ANB, Wits, and Harvold at the 0.05 confidence level. Therefore, the skeletal pattern accurately reflects the underlying dental relationship. 3. Ratios differed in the various categories when compared to the total population with increased correlations noted for some groups. The average FMA group showed the least variability of all the categories since the range was the smallest (25-30 degrees). 4. Although skeletal parameters are often highly correlated, their association may prove to be contradictory in patients with severe skeletal disharmonies.
本实验结果揭示了在不同程度下颌旋转情况下，牙齿与骨骼参数之间存在重要关联。颅面复合体的结构要素在大小、形态模式上存在差异，并且它们的空间关系决定了牙弓的关系。这些比较结果支持以下假设，即下颌平面角的变化也伴随着颅面关系的显著差异。1. 在下颌旋转程度与任何组或总样本的牙齿分类之间未发现显著关联。2. 在0.05置信水平下，确定了牙齿分类与ANB、Wits和Harvold水平骨骼测量值之间存在显著相关性。因此，骨骼模式准确反映了潜在的牙齿关系。3. 与总体人群相比，不同类别中的比率存在差异，一些组的相关性有所增加。平均FMA组在所有类别中变异性最小，因为其范围最小（25 - 30度）。4. 尽管骨骼参数通常高度相关，但在严重骨骼不协调的患者中，它们之间的关联可能是相互矛盾的。
