文题释义:
错牙合畸形Angle分类法:第一类错牙合(中性错牙合)为正中颌位时,上颌第1磨牙的近中颊尖咬合于下颌第1磨牙的近中颊沟内,可表现为牙列拥挤,上牙弓前突,双牙弓前突,前牙反颌,前牙深覆合,后牙颊舌向错位等;第二类错牙合(远中错牙合)为正中颌位时,下颌及下牙弓处于远中位置,磨牙为远中关系,可表现为:上前牙前突,前牙深覆合深覆盖,上唇发育不足和开唇漏齿,亦可表现为内倾性深覆合,面下1/3过短,颏唇沟较深等;第三类错牙合(近中错牙合)为下颌及下牙弓处于近中位置,磨牙为近中关系,可分为骨性三类和牙性三类错牙合,临床上可表现为:前牙对合,反合或开合,上颌后缩或下颌前突等。

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类错牙合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类错牙合患者各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,P < 0.05),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,P < 0.05);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,P < 0.05),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,P < 0.05);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: Location relationship between maxillary incisor labial inclination and the thickness of anterior alveolar bone displays ethnic and regional differences.
OBJECTIVE: To study the correlation of alveolar bone structure and incisor labial inclination in adolescents with skeletal class II malocclusion in Uygur and Han populations of Xinjiang, China.
METHODS: Sixty Uygur and 60 Han patients at 11-16 years of age (average 13.8 years old), 32 males and 28 females, with skeletal class II malocclusion were included. The thickness of anterior alveolar bone and incisor labial inclination were measured on lateral cephalometric films, and the results were analyzed using SPSS 17.0 statistical software.
RESULTS AND CONCLUSION: In Han and Uygur populations, palatal alveolar bone thickness in maxillary incisor region was significantly negatively correlated with the inclination of maxillary incisor (r=-0.715 for Han, r=-0.651 for Uygur, P < 0.05), while labial alveolar bone thickness in mandibular incisor region was significantly positively correlated with the lower incisor inclination (r=0.902 for Han, r=0.745 for Uygur, P < 0.05). These results indicate that the palatal alveolar bone thickness in maxillary incisor region decreases with the increase of the inclination of maxillary incisor; however, the labial alveolar bone thickness in mandibular incisor region increases with the increase of the lower incisor inclination.
