Objectives: To analyze the mean anterior alveolar bone thickness among patients presenting with malaligned teeth.
Materials and Methods: This cross-sectional study was conducted in the “Department of Orthodontics, Altamash Institute of Dental Medicine”, Karachi, Pakistan from 1st Dec 2024 to 31st May 2025. A total of 100 patients with malaligned teeth, full permanent dentition, and clear lateral cephalograms were included. Malocclusion was classified using Angle’s criteria, and lateral cephalograms were hand-traced by a single examiner. Alveolar bone thickness was measured. Continuous variables were reported as mean ± SD, categorical variables as frequency and percentage. Chi-square or Fisher’s exact test, one-way ANOVA, and independent t-test were applied, with p < 0.05 considered statistically significant.
Results: The mean age was 19.78 ± 6.20 years, with 53% females. Maxillary alveolar bone thickness averaged 10.02 ± 1.55 mm with no significant differences among malocclusion groups (p = 0.121). Mandibular thickness varied significantly (p = 0.003), highest in Class III (12.00 ± 3.32 mm). Maxillary labial bone was thinner in Class II (4.62 ± 1.41 mm) than Class I (5.58 ± 1.57 mm; p = 0.008), and mandibular lingual bone was thicker in Class III (5.75 ± 1.19 mm; p = 0.0005). No significant gender differences were observe.
Conclusion: Alveolar bone thickness varies with malocclusion type. Thinner maxillary labial bone in Class II and thicker mandibular bone in Class III emphasize the importance of individualized orthodontic planning to safeguard periodontal health.
