MAMP therapy with MARPE expander
Twenty patients will be submitted to MAMP therapy with MARPE expander as anchorage in the maxillary arch. The appliance anchorage will be provided by bands adapted on the maxillary first permanent molars and circumferential clamps in the maxillary canines or premolars. The maxillary and mandibular miniscrews will be placed in the same section. After a 24-hour period, parents will be oriented to activate the expander screw. Patients will be instructed to wear intermaxillary elastics connecting the maxillary first molar hooks to the mandibular mini-implants.
MAMP therapy with Hyrax expander
Fifteen patients will be submitted to MAMP therapy with Hyrax expander as anchorage in the maxillary arch. The appliance anchorage will be provided by bands adapted on the maxillary first permanent molars and circumferential clamps in the maxillary canines or premolars. The mandibular miniscrews will be placed and after a 24-hour period, parents will be oriented to activate the expander screw. Patients will be instructed to wear intermaxillary elastics connecting the maxillary first molar hooks and the mandibular mini-implants.
