Purpose To evaluate labial and palatal bone thickness at the maxillary anterior teeth as well as distance from cemento‐enamel junction (CEJ) to bone crest using cone beam computed tomography (CBCT). Materials and Methods Measurements were obtained for maxillary anterior teeth of 120 subject CBCT volumes including thickness of labial and palatal plates of bone (coronal, middle, and apical thirds), and distance between CEJ and alveolar bone crest mid‐labially, mesially, and distally. Results The mean value of bone thickness at coronal, middle, and apical thirds of the labial side for central incisor roots were respectively: 0.73, 0.69, 0.60 (mm), for lateral incisors: 0.70, 0.61, 0.49 (mm), and for canines: 0.74, 0.53, 040 (mm). The thickness of palatal bone was significantly larger. The mean distance between CEJ and mid‐labial bone crest for all sites was 2.16 mm. Conclusion Labial bone thickness is thin in the vast majority of maxillary anterior teeth. Use of CBCT facilitates planning for immediate implant placement and is helpful in the decision‐making process when further bone augmentation is needed.
