Impact of Sagittal Skeletal Patterns on Alveolar Bone Thickness Around Mandibular Incisors: A Cone-beam Computed Tomography Study

IntroductIonThe evaluation of alveolar bone thickness (ABT) is a critical component in orthodontic diagnosis and treatment planning, as it dictates anchorage feasibility and determines the safe boundaries for tooth movement.ABT is a key anatomical determinant, and exceeding physiological limits may lead to periodontal complications, including dehiscences, fenestrations, and gingival recession. 1,2Some of the most significant orthodontic movements include dental arch expansion and the buccal-lingual movements of the incisors, both of which are limited by the morphology of the alveolar bone. 3andibular incisors are often the limiting element in orthodontic treatment planning due to their minimal amount of labiolingual bone support. 4Their positioning within alveolar housing significantly impacts treatment mechanics, stability, and the final result of orthodontics. 5The variation in ABT around the incisors is influenced by underlying skeletal patterns, which affect
