Abstract
Objective: To determine if patients with cleft lip and/or cleft palate (CLP) with dental correction of the anterior crossbite during growth display differences in alveolar bone thickness around the maxillary central incisors compared to patients without crossbite correction.
Methods: This retrospective study evaluated post-treatment cone beam computed tomography (CBCT) images of growing patients with CLP with anterior crossbites who underwent Phase I orthodontic treatment (n=32). CBCTs were sorted by whether the crossbite was corrected (n=16) or not corrected (n=16) during Phase I. Alveolar bone thickness was measured on the buccal and palatal aspects of the central incisors at 3 mm, 6 mm, and 8 mm apical to the CEJ, and dehiscence length was measured on the buccal and lingual.
Results: Incisors in the correction group displayed significantly thicker bone on the lingual at 6 mm (p=0.0087 sagittal, 0.0094 axial) and 8 mm (p=0.0184 sagittal, 0.0251 axial). At these locations, there was also significantly thicker bone surrounding incisors closer to the cleft in both sagittal (p=0.0340) and axial views (p=0.0064). The interaction was not significant indicating that the difference between cleft and non-cleft sites was not associated with crossbite correction (p=0.6298 sagittal, 0.9069 axial). None of the other locations demonstrated significant differences in bone width or dehiscence length between the correction and non-correction groups.
Conclusion: Correction of the anterior crossbite in growing CLP patients was not associated with adverse effects on the periodontium and can be considered a viable treatment option to improve function and esthetics for patients during adolescence.
