NTI-tss stands for Nociceptive Trigeminal Inhibition tension suppression system. NTI is a small oral appliance used for patients who clench/grind and/or get migraine headaches. It is made out of acrylic that is custom-molded to your front teeth. It works by preventing your teeth from coming together and “reprograms” your jaw muscles. All that is needed is an impression of your upper and lower teeth. We send the impressions to a lab where the appliance is fabricated. Once we have the appliance fitted and the patient is compliant, we will see the patient back for an evaluation on improvement and/or minor adjustments. If you have migraines or clench and grind at night, please contact our office to schedule an appointment to see if an NTI appliance can help you!
