摘要:

目的：探讨骨性Ⅱ类高角患者合平面与下颌骨位置之间的相互关系。方法：选取45例成人女性骨性Ⅱ类高角患者正畸治疗前头颅定位侧位片，各测量29项指标。应用多元逐步回归分析下颌骨位置指标与合平面指标、合平面指标与牙齿指标的相关性。结果：下颌骨位置与后牙合平面倾斜度相关性显著。后合平面倾斜度与上颌第二磨牙垂直高度及倾斜度、上颌第二前磨牙垂直高度相关性显著。结论：骨性Ⅱ类高角患者下颌骨位置与后合平面倾斜度关系密切。

Abstract:

Objective:To explore the relation between occlusal plane and sagittal position of the mandible in skeletal Class Ⅱ hyperdivergent malocclusion. Methods: Forty-five adult females with high-angle skeletal Class Ⅱ malocclusion were selected .Lateral cephalograms were performed in 45 adult females and twenty-nine measurements of skeletal and dental for each person were obtained.The correlation of sagittal position of the mandible and occlusal plane parameters was evaluated by multiple stepwise regression analysis, as well as correlation between the occlusal plane and the dental patterns. Results: Sagittal position of the mandible and cant of posterior occlusal plane were significantly correlated with each other. The height of upper second molar and upper second premolars and the inclination of upper second molar significantly were correlated with cant of posterior occlusal plane. Conclusion: We can find significant correlation between cant of posterior occlusal plane and different sagittal relationship of maxillary and mandible in patients of skeletal Class Ⅱ hyperdivergent malocclusion.
