| Popis: | Introduction: The aim of this study was to compare the dentoalveolar effects of slow (SME) and rapid (RME) maxillary expansions in patients with bilateral complete cleft lip and palate. Methods: A total of fifty patients with bilateral complete cleft lip and palate diagnosed with maxillary dental arch constriction were randomly and equally divided into two groups. The SME group was comprised by patients who underwent slow maxillary expansion using quad helix appliance, and the RME group was composed by individuals who underwent rapid maxillary expansion using Hyrax expander. Digital dental models were acquired immediately pre-expansion (T1) and 6 months after the active expansion period (T2). Maxillary dental arch widths, arch perimeter, arch length, palatal depth and buccolingual inclination of posterior teeth were measured. Intergroup and inter-phase comparisons were performed with Students t test and paired t test, respectively (p |
