Comparison of Occlusion in Patients with Complete Unilateral Cleft Lip and Palate after One-stage and Two-stage Treatment
Objective: To evaluate and compare dental occlusions at the mixed dentition stage in two groups of patients with complete unilateral cleft lip and palate, who underwent one-stage simultaneous closure and two-stage closure.
Design: Twenty-three patients with complete unilateral cleft lip and palate were divided into two groups. Twelve patients underwent one-stage operation of the lip and palate closure (mean age 14.92±4.81 months); eleven patients had the lip and palate closures carried out in two different stages (mean age of lip closure 4.45±2.46 months and palate closure 13.73±3.00 months).
Materials: Dental models of children at 6 to 12 years of age.
Methods: Study models were measured for the anterior arch width, posterior arch width, anterior overjet, anterior overbite, anterior crossbite, and posterior crossbite. The outcomes from those one-stage and two-stage operations were compared.
Results: No statistically significant differences between the two groups were revealed.
Conclusions: There was no difference in the development of the occlusal relationship between one-stage and twostage operations in those patients at the mixed dentition.
