【摘要】：背景:研究指出上颌前牙唇倾度与前牙区唇腭侧牙槽骨厚度的空间位置关系,X射线头影测量存在种族和地域的差异。目的:对新疆维吾尔族及汉族青少年骨性Ⅱ类错鉭不同垂直骨面型患者切牙区牙槽骨形态结构与切牙唇倾度进行相关性分析。方法:选取维吾尔族及汉族年龄在11-16岁骨性Ⅱ类错鉭患者各60例,平均年龄13.8岁,拍摄头颅定位侧位片并测量上下前牙区牙槽骨厚度和前牙唇倾度,利用SPSS 17.0统计软件对测量结果进行比较分析。结果与结论:(1)汉族:上颌切牙根尖腭侧牙槽骨厚度(ULP)与上切牙唇倾度呈负相关(r=-0.715,P0.05),下颌切牙根尖唇侧牙槽骨厚度(LBP)与下切牙唇倾度呈正相关(r=0.902,P0.05);(2)维吾尔族:上颌切牙根尖腭侧牙槽骨厚度(ULP)与上切牙唇倾度呈负相关(r=-0.651,P0.05),下颌切牙根尖唇侧牙槽骨厚度(LBP)与下切牙唇倾度呈正相关(r=0.745,P0.05);(3)结果说明,维吾尔族及汉族上颌切牙根尖腭侧牙槽骨厚度随着上颌切牙唇倾度增大而减小,下颌切牙根尖唇侧牙槽骨厚度随下切牙唇倾度增大而增大。
[Abstract]:Background: the relationship between the degree of labial inclination of maxillary anterior teeth and the thickness of alveolar bone of labial and palatine side in the anterior teeth was pointed out. There were racial and regional differences in cephalometric measurement of maxillary anterior teeth. Objective: to analyze the correlation between alveolar bone morphology and labial inclination of incisor in Xinjiang Uygur and Han adolescents. Methods: 60 Uygur and Han nationality patients aged 11 to 16 years old, with an average age of 13.8 years, were selected. Lateral radiographs were taken to measure the alveolar bone thickness and labial inclination of the upper and lower anterior teeth. SPSS 17.0 statistical software was used to compare and analyze the measurement results. Results and conclusion in Han nationality, the thickness of alveolar bone of maxillary incisor was negatively correlated with the degree of labial inclination of maxillary incisor, and the thickness of alveolar bone of mandibular incisor was positively correlated with the degree of labial inclination of lower incisor.) Uygur: maxillary incisor There was a negative correlation between the alveolar bone thickness of the apical palatal side and the labial inclination of the upper incisor. There was a positive correlation between the alveolar bone thickness of the mandibular incisor and the labial inclination of the lower incisor. The results showed that there was a positive correlation between the thickness of the alveolar bone of the mandibular incisor and the labial inclination of the lower incisor. The thickness of alveolar bone of maxillary incisor decreased with the increase of labial inclination of maxillary incisor, and the thickness of alveolar bone of maxillary incisor increased with the increase of labial inclination of lower incisor in Uygur and Han nationality.
