Maxillary transverse deficiency generally requires the widening of the palate. In mixed dentition patients, Rapid Maxillary Expansion (RME) is a reliable treatment modality. However in adults patients are frequently suggested to opt for more invasive procedures, like the Surgically Assisted Rapid Palatal Expansion (SARPE) expansion. The pursuit of minimally invasive expansion devices that facilitate purely orthopedic movement has prompted researchers to integrate mini-implants with traditional Rapid Maxillary Expansion (RME). Microimplant-Assisted Rapid Palatal Expansion (MARPE) optimizes skeletal expansion while reducing undesirable dentoalveolar consequences, thereby eliminating the necessity for orthognathic surgery. In this case report, we have descripted a mini-implant–supported expansion of the maxillary arch in a patient with a bilateral posterior crossbite.
