Modified-casted Appliance for Surgically-assisted Rapid Palatal Expansion: A Clinical Report

Abstract

Transverse maxilla-mandibular discrepancies are a major component of several malocclusions. Surgically assisted rapid palatal expansion (SARPE) is a common treatment modality for older patients in the correction of a maxillary transverse deficiency. In such cases, retention of the appliance plays an important role and this becomes a problem in patients having enamel hypoplasia. Therefore, the design was modified of a tooth-borne rapid maxillary expansion appliance with provision for miniscrew skeletal anchorage in a Class II malocclusion case having anterior open bite with bilateral posterior crossbite and enamel hypoplasia.
