摘要
目的:用锥形束CT(CBCT)分析上颌中切牙根径及周围骨厚度等情况,为前牙美学区即刻种植提供临床参考依据。方法:选取299例成年患者CBCT影像资料,分别测量上颌中切牙秞牙骨质界(cemento-enamel junction,CEJ)下2mm处牙根的唇腭径/近远中径和唇腭/近远中侧骨板厚度,观察骨开裂/开窗情况,并对不同性别、年龄组差别进行统计学分析。结果:女、男性两切牙唇侧骨开窗分别为9、14例,同一牙位发生率无明显统计学差异(P>0.05)。同一牙位,男性唇腭径、近远中径均大于女性(P<0.05),女性唇侧骨板厚度大于男性(P<0.05),30岁以下组唇侧骨板厚度大于31～50岁组及50岁以上组(P<0.05)。结论:CBCT可以精确测量牙根直径,上颌中切牙CEJ下2mm处近远中径、唇腭径及唇侧骨厚度与性别有关,30岁以下人群唇侧骨板厚。
Objective:To measure root diameter and bone thickness overlying maxillary central incisors to offer more details for immediate implantation in esthetic area.Methods:299 patients with CBCT image data were included.Labial-palatal and mesial-distal diameter,labial,palatal,mesial and distal bone thickness,2mm below the cemento-enamel junction(CEJ)were measured.Gender and age difference were analyzed.Results:There were 9 and 14 fenestrations and dehiscences for female and male(P >0.05).Significance was found in different genders for labial-palatal and mesial-distal diameter(P<0.05).Female or group below 30 had more labial bone(P<0.05).Conclusion:CBCT can be applied for precise measurement.Both mesial-distal and labial-palatal root diameter,2mm beneath the CEJ,had correlation with gender.Thicker bone was found below 30.
