rapid maxillary expansion in children with cleft lip and/or palate; a 3d evaluation of the effects of two different orthopedic expanders
Adolsecents with cleft lip and palate (CLP) quite frequently suffer from maxillary transverse deficiency, requiring orthopedic expansion of the maxilla to achieve proper occlusion and dimensions of the dental arches. The aim of the current study was to evaluate the skeletal and dentoalveolar effects of rapid maxillary expansion (RME) in children with CLP treated with the banded hyrax and fan-type expanders. Twenty Egyptian children with complete 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 and immediately after expansion procedure. Three dimensional evaluation results will be revealed along with our recommendations for optimum results and realistic treatment objectives.
