Abstract

The canine fossa is an important facial concavity on the labial surface of the maxilla, which needs to be considered when placing implants in the maxillary canine and premolar region. The present study assessed the canine fossa and analyzed the depth and distance of its deepest point from the root apex as a guide for immediate implant placement. 100 cone beam computed tomography (CBCT) scans taken between January 2017 and December 2021 were analyzed in the sagittal section, evaluating the depth of the canine fossa and its proximity to the root apex. The average depth of the canine fossa was 1.62 ± 0.54 mm, and the distance between the deepest point of the fossa and the root apex was 4.52 ± 1.70 mm. No significant correlation was found between these parameters and gender or age (p > 0.05). It can be concluded that the canine fossa is near the roots of the canine and first premolar, increasing the risk of fenestration of buccal bone during immediate implant placement.
