Context: The major motivation for patients to get orthodontic treatment is the unesthetic placement of incisors. Therefore, correction of these anterior teeth is of prime importance along with their position in the alveolar housing during treatment planning. Aim: This study aimed to evaluate the alveolar bone thickness around the incisors in various skeletal patterns. Materials and methodology: A total of 128 lateral cephalograms of patients visiting the department were traced and divided into four groups (n = 32) based on the sagittal relationship including class I with a bimaxillary protrusion, class II division 1, class II division 2, and class III. The total root length, incisor inclinations, and labial and palatal alveolar bone at the middle and apex of maxillary and mandibular central incisors were measured and subject to statistical analysis using the statistical package for the social sciences (SPSS), version 25, software. Results: According to the analysis of variance (ANOVA) and post hoc Tukey honestly significant difference (HSD) tests, there were significant differences between groups in alveolar bone widths of maxillary central incisors at apex and middle. While no significant difference was seen in the case of the middle of mandibular central incisor roots, the alveolar bone width was found to be significant in intergroup comparison at the apex. The inclination of incisors was also significantly different between the groups. Conclusion: The current study showed the dental compensation by central incisors in various sagittal patterns. The palatal bone in maxillary incisors was thinner in class I and class II division 1 due to proclination while the labial bone was thinner in incisors of class II division 2 and mandibular incisors in class III.
