A Rapid Palatal Expander (RPE) or Hyrax is used to widen the upper jaw so that the bottom and upper teeth fit together better. This appliance is used to widen one or both sides of the upper jaw, to manage the height of the face and to tip teeth.
The patient will make one (1) turn each day for 28 days. If all goes as planned, activation may be complete at the end of the 28 days. At that time Dr. Mendez will decide if more turns are necessary.
Each time the Swivel key is inserted into the hole in the screw and turned until the key touches the housing. That is considered to be one turn. For each full revolution of the screw, one mm of expansion is achieved. The appliance is allowed to remain inactive for six months or more for the bone to fill in.
When you brush your teeth, brush your Hyrax or RPE also.
Make sure there is no food left between the palate and the appliance.
Use mouthwash every time you brush your teeth.
Taking care of your Hyrax or RPE doesn’t have to be difficult. Remember it’s not forever and if don’t listen to your orthodontist your result are not going to be favorable for the treatment.
