Assessment of Anterior Maxillary Alveolar Ridge Dimension and Morphology - A Retrospective Analysis of Cone Beam Computed Tomography Images in South Indian Population

Abstract

Purpose: Rehabilitation of missing maxillary anterior teeth with implants is very challenging as aesthetics dominates the outcome, CBCT is an invaluable tool aiding in radiographic assessment. Materials and Methods: A retrospective assessment of 84 CBCT scans of maxillary central, lateral incisors and canines (252 teeth) was done to evaluate alveolar height, width, buccal undercut location. Gender comparison was done for the above mentioned parameters. Results: The average alveolar height and width at maxillary anterior region ranged between 17.47 and 11.12 mm, respectively. Alveolar width was more for centrals and canines. The lateral incisors had deep buccal undercut. There was no significant difference in parameters among genders. Conclusion: The study adds to the ridge dimensions data and throws light on the precautions needed for implant planning. Lateral incisors need special precautions. Alveolar dimension assessment will have a direct influence on aesthetic outcome and stability of implants. The study adds emphasises detailing of essential precautions and thorough radiographic evaluation for successful outcome
