Accuracy of cone beam computed tomography in measuring alveolar bone height and detecting dehiscences and fenestrations in patients undergoing periodontal surgery

Cone-beam computed tomography (CBCT) has greatly expanded opportunities for evaluating craniofacial morphology, including alveolar bone structures. However, research on the accuracy of CBCT in assessing bone morphology remains limited, with most studies relying on phantoms, dry skulls, or cadaver specimens. The objective of this study was to determine the accuracy and reliability of CBCT imaging for measuring alveolar buccal bone height (BBH) and for diagnosing naturally occurring fenestrations and dehiscence. This was achieved by comparing CBCT measurements with direct in vivo assessments.
