目的:应用锥形束 CT(CBCT)研究成人骨性Ⅱ类错(牙合)患者前牙区牙槽骨形态特征及垂直骨面型对其的影响。方法:纳入64名成人骨性Ⅱ类错(牙合)患者,对照组选择正常(牙合)15名,进行锥形束 CT 的拍摄,对前牙区牙槽骨各项数据进行对比分析;并将骨性Ⅱ类错(牙合)患者根据垂直骨面型的不同进行分组整理分析。结果:骨性Ⅱ类错(牙合)患者前牙区唇舌侧牙槽骨高度及厚度均低于对照组(P <0.05)。骨性Ⅱ类错(牙合)高角组患者前牙区唇舌侧牙槽骨高度、牙槽骨厚度均低于低角组(P <0.05)。结论:骨性Ⅱ类错(牙合)患者前牙区牙槽骨厚度尤其是切牙区牙槽骨厚度较低,高角组低于低角组。
Objective:To study the alveolar bone morphology in the anterior teeth area of the skeletal Class Ⅱ malocclusion subjects with different vertical skeletal types.Methods:64 patients with skeletal Class Ⅱ malocclusion and 15 subjects with normal occlusion were included.The alveolar bone structure of the anterior teeth were observed using CBCT.Results:The labial and lingual alveolar bone height and the alveolar bone thickness of the incisors of the patients were much lower than those of the normal controls.The height of labial and lingual alveolar bone and the alveolar bone thickness of anterior teeth in high-angle subgroup were lower than those in low-angle subgroup.Conclusion:The thickness of the anterior teeth alveolar bone of skeletal Class Ⅱ malocclusion is low,espe-cially in the high-angle group.
