| Purpose: The purpose of this clinical study was to evaluate the treatment outcomes recorded by cone beam computed tomography (CBCT) of slow maxillary expansion protocol (SME) on cleft palate patients, using a differential opening expander (EDO) and face mask (FM). Materials and methods: Eight CLP children with maxillary arch constriction and deficiency were chosen. The patients were treated with EDO and FM. Cone-beam computed tomography (CBCT) scans were done prior to expansion and after expansion with six months. Maxillary width, maxillary alveolar width, SNA, SNB and ANB were assessed. Interphase comparisons were performed using paired t-tests (PResults: SME using EDO promoted significant increases in maxillary width (1.94±0.27 mm) and maxillary alveolar width (3.91±0.31 mm) at the molar region. Also, it promoted significant increases in maxillary width (3.93±0.29 mm) and maxillary alveolar width (2.04±0.18 mm) at the premolar region. Maxillary protraction using FM promoted significant increases in SNA (2.90±0.99º) and ANB (5.55±0.96º) angles, and a significant decrease in SNB angle (-2.65±0.30º). Conclusion: In children with CLP, SME using EDO and maxillary protraction using FM caused orthopaedic and dentoalveolar changes in transverse and sagittal dimensions, respectively. | ||||
