Description

Abstract

Transverse maxillary deficiency is a common dentofacial anomaly characterized by posterior crossbite, arch constriction, and compromised nasal airflow. Traditionally, correction in growing patients has relied on conventional rapid maxillary expansion (RME), which separates the midpalatal suture using tooth-borne appliances. However, in late adolescence and adulthood, increasing interdigitation and ossification of the suture reduce skeletal responsiveness, often resulting in undesirable dental tipping and alveolar bending. The advent of miniscrew-assisted rapid palatal expansion (MARPE) offers a hybrid, bone-anchored solution capable of achieving true skeletal expansion beyond the limits of conventional RME. This review explores the evolution, biomechanics, indications, and clinical protocols of MARPE, emphasizing its role as a minimally invasive alternative to surgically assisted expansion (SARPE). Recent clinical and radiographic evidence supporting skeletal, dental, and airway outcomes are critically analyzed, along with considerations for patient selection, retention, and complications. MARPE represents a paradigm shift in transverse maxillary correction, bridging the gap between traditional orthodontic expansion and orthognathic surgery.
