Sleep apnea is a condition that is characterized by shallow or a complete cessation of breathing while asleep. Obstructive Sleep Apnea, or OSA, is a lack of breathing during sleep caused by obstructed airways. One way OSA is treated is through the use of mandibular repositioning devices, which essentially are a kind of retainer that helps keep airways propped open by either supporting the jaw or holding the tongue. However, everyone reacts differently to this kind of treatment and it can often be difficult to tell if something is working or not. Currently, only 50% to 70% of patients report that their sleep apnea is being treated successfully. This is where MATRx comes in.

What Is MATRx?

MATRx is the name of a polysomnography test, a kind of diagnostic tool used in sleep medicine, which can be used to gather data to find out who is successfully responding to the treatment of Obstructive Sleep Apnea using mandibular repositioning devices. Normally, a polysomnogram is performed to record changes in all kinds of biological and physiological data from you as you sleep. The MATRx system is designed to integrate with polysomnograms to better monitor patients. Dentists can then analyze the data gathered by MATRx to hopefully design a fitted oral appliance that’s customized for a patient’s needs. These kinds of oral appliances are commonly used to treat OSA as they’re non-intrusive, removable, and easy to use.

What Does This Mean for Me?

If you or someone you know is suffering from sleep apnea, MATRx can help customize your treatment for you. It allows dentists to gather data for an evidence-based approach to your therapy. You’ll find that the system has been well designed and won’t disturb your sleep when you come in for testing. If you’re selected for MATRx, you’ll first go into the dental office so the dentist can assess your jaw and its range of motion. A technician will insert the MATRx trays and perform the study. Afterwards, the results will be given to your doctor, who will see how you’re responding to the oral appliance therapy. Ultimately, the hope is to provide you with a customized retainer to wear that will help treat your sleep apnea.

What Are the Benefits of MATRx?

MATRx has been validated in 3 clinical trials and reported on in 2 peer-reviewed studies. It’s shown to have high predictive accuracy and a sensitivity of 86%.
