Abstract:

Objective To analyse the characteristics of appearance of dental arch of patients with unrepaired cleft palate. Methods Forty patients with unrepaired nonsyndromic cleft palate were collected, among whom 15 had unilateral cleft lip and palate (UCLP) with the mean age of 20.2 years old, and the other 25 had isolated cleft palate (ICP) with the age of 21.8 years old. Dental cast assessments were conducted in two groups. Besides, 40 age and gender-matched patients with classⅠ malocclusion were served as controls. Results Compared with controls, patients with UCLP had decreased anterior dental-arch width, anterior dental-arch length and total dental-arch length (P<0.05), while those with ICP had increased posterior dental-arch width, decreased anterior dental-arch length and total dental-arch length (P<0.05). Conclusion There exist inhibitory effects of sagittal growth and maxilla development in patients with unrepaired cleft palate, while inhibitory effects of transverse growth in canine region only exist in patients with UCLP.
