Transverse maxillary atrophy in adult dentate patients is usually performed with the surgical assisted rapid palatal expansion (SARPE) technique. In edentulous patients, the bone-borne technique originally described by Mommaerts can be used, as an alternative to onlay bone grafting. We describe an alternative method to increase the transverse diameter of the maxilla in an edentulos patient by using the SARPE technique and an Hyrax screw connected to dental implants. Four implants were inserted in the maxilla, two on each side, and after 7 months a surgical assisted rapid palatal expansion was performed by using an Hyrax device. When a satisfactory transverse maxillary dimension was achieved, 4 more implants were positioned and a full-arch implant rehabilitation was obtained.
