Description
Summary:Background: Alveolar bone loss is a well-known consequence of tooth loss which is exhibited as overall reduction in its dimensions over a period. It is highest in mediolateral plane than coronoapical plane. It is important to know the volume of bone loss as it determines treatment plan with a provision to get possible treatment options. Objectives: The objectives of the study were to quantitatively measure the amount of residual alveolar bone resorption after resorption labially/buccally in horizontal plane Materials and Methods: Retrospective data were collected from the archives of the cone-beam computed tomography (CBCT) scans of the patients aged 18 years and above with one or two missing teeth with at least one abutment tooth on either side. The scans were subjectively analyzed for the type of contour defects and objectively analyzed for depth of alveolar bone deformity in mediolateral plane using active measurement mode tool. Results: Out of 400 scans screened, 112 scans had 138 edentulous sites. Mandible had 86 edentulous sites; maxilla had 52 edentulous sites. All scans showed resorptive changes amounting to 100% of findings. The lowest value was 0.6 mm and the highest value was 4.1 mm. The age ranged from 18 to 76 years. Conclusion: Alveolar bone resorption invariably occurs following removal of teeth giving rise to concave deformity and is more pronounced buccopalatally, which was up to 4.1 mm in the present study. Palatal bone is more resistant to resorption. CBCT is a valuable tool for assessing the dimensional changes in the alveolar bone.
