[摘要]目的 探討分析成人骨性Ⅱ类成人错 不同垂直骨面型患者切牙代偿情况的差异,为临床诊治提供参考依据。方法 选取2015年1月~2018年1月我院收治的105例成人骨性Ⅱ类错 患者作为研究对象,所有患者治疗前进行头颅侧位片拍摄,并按颅底平面和下颌平面夹角(SN/MP角)将患者分为高角组(n=23)、均角组(n=47)、低角组(n=35)三种不同的垂直骨面型,将成人骨性Ⅱ类错 患者与正常 的头影测量结果比较,并分析各组切牙倾斜度指标的差异。结果 成人骨性Ⅱ类错 患者的下颌中切牙与下颌平面交角(L1/MP)、下颌中切牙与NB平面交角(L1/NB)高于正常 ,上下颌的中切牙夹角(U1/L1)则低于正常 ,差异有统计学意义(P0.05)。在上切牙唇倾度方面,高角组的上颌中切牙与颅底平面夹角(U1/SN)低于低角组,上颌中切牙与上颌平面交角(U1/PP)高于低角组,差异有统计学意义(P0.05). In the upper incisor, the angle between maxillary central incisor and skull base plane (U1/SN), angle between maxillary central incisor in the high angle group was lower than that in the low angle group, maxillary plane (U1/PP) in the high angle group was lower than that in the low angle group, angle between maxillary central incisor in the high angle group was higher than that in the low angle group, and the differences were difference was statistically significant (P, 百拇医药(刘聪 肖振朋 黄坚愧) 第 1 2 3 页 下一页
