Quad Helix

Screen Shot 2013-05-11 at 8.02.01 AM

Overview

This fixed appliance is different from other expanders in that it doesn’t require patient compliance & expands the upper jaw more slowly, thus creating a more gentle physiological response. This is an excellent appliance to expand narrow upper jaws & to  treat mild-moderate crowding and or cross-bites. The appliance must remain in your mouth for about 4-6 months.

  • Take over the counter pain medication as needed for any discomfort.

  • Moderate sensitivity and pressure is normal during your first 1-2 weeks with the expander.  If excess pain or swelling occurs, don’t hesitate to contact Dr. Yoon through this site, or call your primary office directly.

  • As usual, stay away from hard, sticky, sweet foods which may distort the appliance.

  • It is essential to keep the QH (quad helix) clean.  This means that the QH should get the same attention your teeth get ( and then some!).  A water-pik and frequent mouth swishing can be a great addition to regular brushing of your teeth and of your appliance.

 

Common Concerns

  • If you experience any of the below, Do Not Worry as these are common symptoms and will get better in a few days.

  • 1.The most difficult thing about a QH is getting used to it.  Your tongue may get irritated or feel swollen.  You may even get a slight imprint of the appliance on your tongue.  This is expected, and will subside.

  • 2.You may feel like you can’t swallow.  With practice, you’ll get used to swallowing with the appliance without any discomfort.

  • 3.Your teeth may feel some discomfort, especially on the outside of the back teeth.  It may help to bite on a rolled up tissue or towel to alleviate the pressure.

  • 4.Speech may be difficult, and you may have a lisp especially during your first few days with the appliance.  Practice speaking out loud at home, and it will improve your articulation.

Emergencies:

  • If your appliance comes loose on both sides, carefully remove it and place it in your case so that it can be re-cemented on your next visit- the appliance may have come loose due to excess manipulation with your tongue/fingers or from a hard/sticky/chewy food or object.

  • If your appliance comes loose on one side, please call the office for an emergency visit so that it can be removed or re-cemented according to the doctor’s instructions.

  • In the event of a real emergency please contact your main office directly or email Dr. Yoon via this site directly.
