Rapid Maxillary Expansion: A Unique Treatment Modality in Dentistry

Rapid Maxillary expansion or palatal expansion as it is sometimes called, occupies unique niche in dentofacial therapy. Rapid Maxillary expansion is a skeletal type of expansion thatinvolves the separation of the mid-palatal suture and movement of the maxillary shelves away from each other. An objective approach to the design of a suitable appliance should be made by preparing a list of criteria based on the biomechanical requirements of RME. RME effects the maxillary complex, palatal vaults, maxillary anterior and posterior teeth, adjacent periodontal structures tobring about an expansion in the maxillary arch. The majority of dental transverse measurements changed significantly as a result of RME.
