Abstract

Maxillary hypoplasia can result in crowding of the maxilla and posterior crossbites, which is a common occurrence. Careful treatment planning is required for comprehensive correction but if utilised well can be successful and stable. RME is a treatment method with the aim of achieving skeletal transverse expansion in patients with posterior crossbites. This case report demonstrates a classic example when RME is useful and discusses essential criteria factors to consider this treatment choice.
