What is MATRx?

The MATRx device determines whether or not an Oral Appliance is the best form of treatment for a patient with Obstructive Sleep Apnea.

OAT - 2

This is an example of an Oral Appliance Device.

Oral Appliance Therapy (OAT) is a mouth piece, similar to the look of a mouth guard, which is used to treat sleep disordered breathing (shown to the right). The appliance brings the lower jaw and tongue forward during sleep; this action opens up the airway, allowing air to flow through and thus reducing and/or eliminating the obstruction blocking the airway. Oral Appliance Therapy is also an option for those who have Upper Airway Resistance Syndrome (UARS). Oral Appliance needs to be customized to each patient in order to reduce or eliminate the presence of Obstructive Sleep Apnea.

For the MATRx study, the patient is fitted with their temporary tray before going to sleep and a small, lightweight device (shown in the picture below); the device shown below is only used during the titration study and weighs 90 grams. The device is controlled remotely and changes the protrusion level (the distance that the lower jaw is brought forward) while the patient is asleep. With the MATRx (pronounced “Matrix”) system, our sleep lab is able to change the protrusion level while a patient is asleep in order to determine the setting at which sleep disordered breathing is significantly decreased or eliminated. The range that the sleep technologists can move the Oral Appliance between is pre-determined by a dentist. If the Sleep Medicine Specialist determines that a patient is a candidate for Oral Appliance Therapy, a dentist (we provide a list) will create an Oral Appliance based on the optimal settings determined during your MATRx study.

This lightweight device, weighing 90 grams (3 oz) is only used during the MATRx titration study.

Why MATRx?

Offers an alternative therapy MATRx offers sleep apnea patients a new treatment option for those who do not clinically respond to CPAP, reject CPAP or who have difficulty tolerating treatment attempts with CPAP. The Sleep Medicine Specialist will determine patient eligibility.
Efficacy of Oral Appliance Therapy MATRx technology includes a comprehensive titration study in the sleep lab which provides objective data used to determine whether a patient is a suitable candidate for Oral Appliance Therapy.
Ensure long term treatment success Oral Appliance Therapy has been shown as a more comfortable treatment option for some patients.

Who should use Oral Appliance Therapy?

Oral Appliance Therapy (OAT) may be an alternative treatment for anyone (subject to Sleep Medicine assessment) who has mild to moderate sleep apnea. Those who are currently using CPAP may also be eligible to use OAT as a secondary form of therapy; in these cases, OAT is used for certain situations, such as travelling. Those who have difficulty tolerating CPAP therapy, may also be considered for OAT, under the direction of a Sleep Medicine Specialist.

How can I get an Oral Appliance?

You will require a referral from your Family Physician for a diagnostic sleep study in order to test whether or not you have a sleep apnea and whether you are a candidate for Oral Appliance Therapy. If you are diagnosed with mild to moderate sleep apnea, you can discuss the option of Oral Appliance Therapy with the Sleep Medicine Specialist during your consultation appointment.

Please note: At this time, MATRx studies are only available at our Paris Location. 

If you are prescribed Oral Appliance Therapy, here is what happens next:

Step 1

Our sleep lab provides a list of dentists who are set up to create the temporary tray necessary for your MATRx study. The dentist, of your choice, will be in contact with you to set up an appointment to have you fitted for a temporary tray.

Step 2

Your temporary tray is brought in for your MATRx study so we can test whether or not Oral Appliance Therapy works for you.

Step 3

If proven successful, the dentist will create your Oral Appliance based on the measurements determined through the MATRx study.

Not successful with Oral Appliance Therapy? You can discuss alternative options with the Sleep Medicine Specialist.

Oral Appliance Therapy must be prescribed by a Sleep Medicine Specialist.
