Abstract

Objective: To compare the morphology of the upper dental arch before and after orthodontic treatment in patients with complete unilateral cleft lip and palate classified as GOSLON 4, using fixed appliances at Vietnam CuBa Friendship Hospital. Subjects and Methods: A non-controlled clinical intervention study with a before-and-after comparison was conducted on 30 patients with complete unilateral cleft lip and palate classified as GOSLON 4, treated with fixed orthodontic appliances at Vietnam CuBa Friendship Hospital from April 2020 to October 2023. Results: After treatment, there was an increase in the width of the upper dental arch at the anterior region, the width between the first molars, the width of the posterior upper dental arch, and the length of the dental arch in the anterior, middle, and posterior regions. The percentage of patients with no midline deviation increased from 37% before treatment to 60% after treatment. The amount of midline deviation decreased by 1.34 mm post-treatment. Conclusion: After orthodontic treatment combined with alveolar bone grafting, both the length and width of the dental arch increased, and the percentage of midline deviation decreased.
