Rapid maxillary expansion

The present appeal of non extraction treatment to correct tooth-size arch form discrepancies has created a renewed interest in alternative methods to increasing arch perimeter. Orthopaedic expansion of the maxillary arch or rapid maxillary expansion (RME) is a viable option to create additional space in the dental arches as well as address transverse discrepancies caused by constricted maxillary arches. It is a commonly used technique and has become increasingly popular during the last 30 years.
