Do long-term dental arch changes after rapid maxillary expansion (RME) affect patients with constricted arches? • Yes. Adolescents gained 6mm in maxillary and 4.5mm in the mandibular arch perimeter. (Evidence level 2). Read the abstract. Is early treatment of unilateral posterior crossbite effective? • Yes. Occlusal adjustment is effective for the primary dentition. Quad-helix (QH), expansion plates and rapid maxillary expansion (RME) are effective in the early mixed dentition. There is, however, no evidence available showing which of these is the most effec
