Abstract

Purpose

This study aimed to perform a longitudinal morphometric analysis of the alterations of the maxillary dental arches of children with cleft lip and palate before and after the primary lip and/or palate surgeries using three-dimensional stereophotogrammetry system.

Methods

The sample consisted of dental casts of 60 children with unilateral complete cleft lip (UCL) and unilateral complete cleft lip and palate (UCLP). Dental arches were evaluated at pre-cheiloplasty (T1), post-cheiloplasty (T2), and 1 year after palatoplasty (T3). Independent t test and Mann-Whitney test were used for intergroup comparisons, and Paired T test, Wilcoxon test, and Repeated-measures ANOVA followed by Tukey test were used for intragroup comparisons.

Results

At T1, the intercanine and intertuberosity distances of group UCLP were statistically greater than those of group UCL. At T2, the maxillary dimensions significantly increased, except for the intertuberosity distance in UCL. Between T1 and T3, the intercanine distance and the anterior length decreased significantly, while the intertuberosity distance and the total length of the palate increased significantly.

Conclusion

According to our results, the primary lip surgery changed the development of the dental arches, evidently in children with UCLP. The primary palate surgery interfered in the growth of the anterior palatal region in group UCLP. The children with UCLP had more restricted development of the maxillary dental arch than children with UCL.
