RAPID PALATAL EXPANDER (RPE) This appliance widens the roof of the mouth by gently separating the suture in the center of the palate. It is sometimes necessary to expand the upper jaw so it will fit properly with the lower jaw or to make room for crowded teeth. The expansion process usually only takes 2 to 4 weeks, however, the appliance remains in the mouth for an additional 6 months while new bone is generated to stabilize the expanded arch.
To Activate your Expander
Insert the key carefully into the hole in the middle of the appliance.
Slowly and steadily push the key from the front, toward the back of the mouth until you see a new hole appear. DO NOT BACKUP. Remove the key toward the back of the mouth.
