Objective: This case report presents cone beam computed tomography (CBCT) three-dimensional (3D) assessment of the buccal bone associated with an implant. Method and Materials: A patient who had immediate implant replacement of a maxillary incisor received a CBCT examination after 6 months. The scanned volume was then subjected to segmentation of the buccal bone associated with the implant and to its three-dimensional rendering. Results: Virtual reconstruction allowed volumetric assessment of the buccal plate, and of the buccal marginal bone level. Conclusion: Creating a 3D virtual volume permits a comprehensive evaluation of the anatomical information contained in the CBCT dataset. Keywords: bone quantity, bone volume rendering, cone beam computed tomography
