Palatal Expander

palatal expander modelThe palatal expander "expands" (or widens) your upper jaw by putting gentle pressure on your upper molars each time an adjustment is made. The animation below will instruct you about when and how to adjust your expander. When you achieve the desired expansion, you will wear the appliance for several months to solidify the expansion and to prevent regression.

Patient Reviews
“The office staff is very friendly and Dr. Hoybjerg is knowledgeable in his field. They let you know step by step what they are doing and what needs to be done, never leaving you guessing what's next. My experience was so wonderful I decided to take my daughter there as well, who is very shy and afraid of pain. They handled her perfectly. I highly recommend Hoybjerg Orthodontics above any other. Not only was it a great experience, but the end result was as well.” ~ April K.
