Cone-beam computed tomography evaluation of bone height and width in 7 different tooth regions of totally edentulous maxilla

Abstract

Aims: The aim of this study was to evaluate the residual alveolar bone height and bone width at different depths from the central tooth region to the second molar tooth region in maxillary totally edentulous individuals. Methods: This retrospective observational radiographic study was performed on cone beam computed tomography images of patients who presented to the department of oral and maxillofacial surgery for dental implant evaluation between January 2010 and March 2023. Horizontal measurements were taken on sagittal cross-sectional images at vertical depths of 1 mm, 3 mm, 5 mm and 7 mm from the alveolar crest. Vertical measurements were made by measuring the distance between the crest of the alveolar ridge and the base of the nose or the base of the maxillary sinus. The results were evaluated with 95% confidence interval and significance at p
