摘要/Abstract

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2 mm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2 mm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。

Abstract: 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.
