Abstract

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.
