The purpose of this study was to determine the maxillary central incisor–incisive canal (CI-IC) relationship by comparing the visibility of the incisive canal on the two-dimensional sagittal images of the central incisors acquired from two cone beam computed tomography (CBCT) reconstruction modalities. A retrospective review of CBCT images from 60 patients (30 men and 30 women) with a mean age of 57.9 years (range: 19 to 83 years) was conducted. The CBCT images were evaluated using the manufacturer’s recommended method (MRM) and a modified method (MM). The CI-IC relationship was classified as invisible, partially visible, or completely visible. The frequency distribution of the CI-IC relationships of the 60 samples indicated that the visibility of the incisive canal is significantly greater at all locations when using the MRM compared to the MM and on the right central incisor versus the left central incisor. Evaluation of the CI-IC relationship using the proposed method may allow the clinician to better determine whether additional surgical procedures are necessary when planning immediate implant placement and provisionalization at the maxillary central incisor positions.
