We can tell in advance if Oral Appliance Therapy (OAT) will work for you by using MATRx Plus testing.
Only 70 perent of patients with obstructive sleep apnea (OSA) can be helped with OAT. The other 30 percent do not respond to OAT and need CPAP treatent. Dr. Wartell has a test that can tell in advance if your obstructive sleep apnea will be improved by OAT. The test, called MATRx Plus, is done at home over two or three nights. It uses a mandiblar positioner that moves your jaw forward and backward while you sleep using temporary splints. The MATRx Plus tells us if you respond well to treatment of OSA with jaw movement, and how far forward your jaw must be for the best effect. There is no guesswork to find the best jaw position. If the MATRx Plus shows you do not respond, there is no point in making a sleep appliance splint. CPAP will be beneficial.
Without MATRx Plus, dentists do their best to determine your jaw position, but it is an educated guess. Approximately one-third of patients with OSA do not respond to oral appliance therapy. For these people, without MATRx Plus testing, they must go through the making of the oral appliance, and then weeks or months of testing it to be sure the appliance is effective. If it is not, the patient will discard the appliance, and need to be fitted for CPAP treatment. What a waste of time, effort, and money!
