Rapid Arch Expansion in Cleft Lip and Palate Children: Comparison Between Fan-Shaped Expander and Hyrax-Type Expander by Using Cone Beam Computed Tomography
Abstract:Purpose:The aim of the current study was to evaluate the skeletal and dentoalveolar effects of rapid palatal expansion (RPE) in children with cleft lip and palate (CLP), ages 8 to 12 years treated with 2 expanders. Methods: Twenty Egyptian children with complete bilateral CLP exhibiting maxillary transverse deficiency were divided randomly into 2 groups according to the appliance used for expansion: (A) fan expander group. (B) hyrax expander group. Cone-beam computed tomography (CBCT) images were taken before … Show more
