Purpose: This retrospective study aimed to evaluate the correlation between buccal and palatal alveolar bone thickness and the degree of maxillary incisor inclination. The objective was to derive clinically relevant insights for orthodontic treatment planning and controlled tooth movement. Materials and Methods: Sixty-one maxillary central incisors from cone-beam computed tomography (CBCT) scans of thirty-four subjects were retrospectively evaluated and grouped as proclined, upright, and retroclined incisors. Buccal and palatal thicknesses of cortical and cancellous alveolar bone were measured at various levels of the incisor root. The correlation between bone thickness and incisor angulation was investigated using Spearman’s correlation test. Results: There was no significant difference between the cortical and cancellous bone thickness at various levels on labial and palatal sides amongst three groups except for the labial cortical bone thickness at 6 mm from the CEJ (PConclusions: The inclination of maxillary incisors is significantly correlated with the thickness of apical cancellous bone. The findings of the study provide valuable information regarding alveolar bone morphology in the anterior maxillary region, supporting precise and biologically sound orthodontic tooth movement planning.
