Técnicas de instalação do aparelho MARPE e suas complicações: revisão de literatura e relato de caso

Abstract

Transverse maxillary deficiency, affecting approximately 10% of the adult population, is characterized by unilateral or bilateral posterior crossbite. Rapid maxillary expansion (RME) is an effective procedure in primary or mixed dentition but is more complex in adults. This study reports a case of a patient with unilateral crossbite due to maxillary atresia, who, at over 30 years old, presented advanced ossification of the palatal suture, leading to the adoption of micro-osteoperforation techniques. The MARPE SL appliance with four orthodontic miniimplants was used following planning with computed tomography. During the procedure, an oronasal communication occurred, which was treated with low-level laser therapy, resulting in healing without the need for additional surgery. The case highlights the efficacy of MARPE and the importance of complementary therapies in managing complications in adults.
