目的 探讨不同面型颌骨骨骼结构特征及其与牙合型的关系。方法 运用X线定位头侧位片 ,图形数字化仪计算机测量分析系统 ,对具有双侧远中磨牙关系 ,前牙深覆牙合深覆盖的凸面型 1 7～ 2 5岁男性 2 0名和具有双侧近中磨牙关系 ,前牙反牙合的凹面型 1 7～ 2 5岁男性 2 0名分别与双侧中性磨牙关系的浅覆牙合浅覆盖的直面型 1 7～ 2 5岁男性 2 0名的颌骨骨骼结构进行比较。结果 面型与牙合型之间存在一定的相关关系和规律性。结论 在对患者进行颌位记录和牙合重建时 ,应结合其颌面部骨骼结构特征 ,恢复其原有牙合型及面型 ,以利于患者咀嚼功能的恢复和口颌系统的健康
Objective To investigate the structural features of different facial jaws and its relationship with occlusal shapes. Methods A total of 20 men and women of convex type 1 7 ~ 25 years old with double-sided distal molar relationship and deep anterior occlusion of deep anterior teeth were covered with a X-ray positioner and a digitizer computerized analysis system. Side of the molar relationship between the anterior teeth anti-occlusal concave type 1 7 ~ 2 5-year-old male 20 and the bilateral neutral molar shallow superficial occlusion shallow covering the face-type 1 7 ~ 2 5-year-old male 2 0 jaw bone structure to compare. Results There is a certain correlation and regularity between the surface type and occlusal type. Conclusion In patients with mandibular position recording and occlusal reconstruction, should be combined with the characteristics of its maxillofacial skeleton structure, restore its original occlusion and face, in order to facilitate the recovery of patients with chewing function and oral health
