OBJECTIVE This meta-analysis evaluated long-term dental and skeletal changes in patients submitted to surgically assisted rapid maxillary expansion. METHODS A search was performed in electronic databases. Human clinical trials with patients submitted to surgically assisted rapid maxillary expansion with a follow-up of at least 1 year after expansion were selected. A methodological quality sco...

BACKGROUND Oral breathing and maxillary deficiency are often associated with steep mandibular plane angle, and retrognathic mandible compared with the faces of healthy controls. Some studies suggested that after rapid maxillary expansion, improvement in nasal breathing and repositioning of mandible with transitory increasing of facial height and, in some cases, spontaneous forward repositioning...

Background: The aim of this study is to evaluate and compare, through bidimensional cephalometry, skeletal dental changes obtained from a rapid maxillary expander (RME) Ni-Ti leaf spring (Leaf) compare them with an untreated control group. Methods: Records consisted lateral cephalograms before after expansion patients that underwent orthodontic treatment at the Department Biomedical, Surgical D...

OBJECTIVE To evaluate the long-term mandibular morphological changes induced by early treatment of class III malocclusion with rapid maxillary expansion (RME) and facial mask (FM). MATERIALS AND METHODS Twenty-five subjects [10 boys, 15 girls; mean age at T1 (start of treatment) 9.3±1.6 years] with class III disharmony were treated with RME and FM therapy followed by fixed appliances. The pat...
