In recent times, sleep disorders and associated breathing difficulties have received significant attention, leading to an increased interest in the study of various maxillary expansion protocols. MARPE has become progressively popular in the management of transverse discrepancies in comparison to traditional expansion methods, due to its augmented skeletal effects. Awareness of early prevention or methods to alleviate sleeprelated breathing disorder symptoms by possibly increasing the airway dimensions has led to an interest in the study of various maxillary expansion protocols. Literature on MARPE, its effects and techniques are quite scarce. This article aims to review the appliance design, miniscrew placement, activation technique and post- expansion outcome parameters and latest advancement in the customized digital manufacturing process.
