摘　　要：目的:应用CBCT评价中国新疆地区成人健康上颌前牙唇侧牙槽骨厚度。方法:选取咬合正常且上前牙健康的200例成人的CBCT图像。测量双侧上中切牙、上侧切牙及上尖牙的唇面3个位点:牙槽嵴顶下方1mm唇侧根面(ML1)、根中1/2唇侧根面(ML2)及根尖(ML3)至牙槽骨唇侧骨壁的距离。结果:ML1、ML2、ML3的平均值(mm)分别为中切牙(1.27±0.55)、(0.92±0.53)、(1.66±0.83)mm,侧切牙(1.19±0.56)、(0.73±0.53)、(1.59±0.77)mm,尖牙(1.36±0.57)、(0.96±0.57)、(1.73±0.96)mm。其中侧切牙ML2小于中切牙ML2(P<0.05),尖牙ML1、ML2大于中切牙ML1、ML2(P<0.05)。左右同名牙在同一位点左右侧均无统计学差异(P>0.05),不同位点比较具有统计学差异(P<0.05)。男性中切牙ML3、尖牙ML2大于女性(P<0.05)。汉族中切牙ML3、尖牙ML3小于维吾尔族(P<0.05)。31~40岁中切牙ML2、ML3,侧切牙ML3、尖牙ML3均小于18~30岁,41~50岁尖牙ML3大于31~40岁(P<0.05)。结论:中国新疆地区成人健康上颌前牙唇侧牙槽骨厚度普遍较薄,上颌尖牙唇侧牙槽骨厚度汉族和维吾尔族之间存在差异。Objective:To assess the thickness of facial alveolar bone in healthy maxillary anterior teeth in the population from Xinjiang area using CBCT.Methods:CBCT images of 200 healthy maxillary anterior teeth were retrospectively collected and analyzed.The labial alveolar bone thickness of maxillary anterior teeth at three locations,in specific,1mm bellow cemento-enamel junction(ML1),middle of root(ML2),and the apical point(ML3)to labial alveolar bone wall,were measured.Results:The mean values(mm)of ML1,ML2,and ML3 for central incisors were(1.27±0.55),(0.92±0.53),and(1.66±0.83)mm;for lateral incisors were(1.19±0.56),(0.73±0.53),and(1.59±0.77)mm;for canine were(1.36±0.57),(0.96±0.57),and(1.73±0.96)mm,respectively.The ML2 of lateral incisors was smaller than that of central incisors(P<0.05),the ML1 and ML2 of canines were larger than those of central incisors(P<0.05).No significant differences were observed between the right and left side incisors,but significant differences between different locations(P<0.05).There were statistically significant differences between genders at ML3 of central incisor and ML2 of canine(P<0.05).There was statistically significant difference between Uyghur and Han groups on the ML3 of central incisor and canine(P<0.05).There were significant differences between years of 18-30 and 31-40 at ML2 and ML3 of central incisor and ML3 of lateral incisor and canine,and between years of 41-50 and 31-40 at ML3 of canine.Conclusion:A thinner labial alveolar bone overlying healthy maxillary anterior teeth was usually present in the population of Xinjiang area.The thickness of labial alveolar bone of canines was different between Uygur and Han.
