In order to create beautiful smiles, sometimes we need to make room for all of your teeth to come in. One way of doing this is by expanding the upper jaw. Until now, the upper jaw has always been expanded in the same way. A jack screw appliance applies instant pressure to the molar area thus forcing the upper jaw to expand. The effect of too much force too fast can result in pain, dizziness and speaking and/or eating difficulty.
We have a better way! Press-on Incremental Expanders (P.I.E.) are a series of plastic palatal expanders that gently increase the width of the upper jaw. This system allows the force of expansion to be delivered slowly over a 24 hour period thus giving the patient’s mouth time to conform to the shape of the appliance. Dr. McSurdy personally designed and patented the appliance (US Patent No. 7,192,273 B2), and it is an important component of our developmental treatment process at The Smile Specialist
