MATRx plus™

Oral Appliance Testing at Home

No More Guesswork

Know who to treat and their target

MATRx plus is the only validated home sleep test that predicts therapeutic outcome with a custom-fitted oral appliance.

MATRx plus is approved by Health Canada for sale in Canada. This device is pending 513(f)(2) clearance and is not available for sale in the United States.

Benefits for You and Your Patients

  • Only treat responders
  • Improve efficiency of appliance fitting at target
  • Decrease time-to-therapy
  • Minimize risk of over-titration
  • “My MATRx plus experience has been life-changing. The system was easy to use and the tablet’s user interface was very intuitive and one of the best I’ve seen. Now that I have the oral appliance, I no longer snore, much to my wife’s delight, and I wake up feeling rested and refreshed.”

  • The MATRx plus makes me more comfortable by ensuring I am only treating patients who will respond to my care. This makes my team members and our patients more confident in referring their friends and family members to me. Offering sleep assistance in general, changes me from just being a technical dentist, to one who can become my patients trusted advisor in maintaining an optimal level of health.
    Dr. Murray Knebel, DDSSierra Centre for Dental Wellness | Calgary, AB
  • "Having anticipated the introduction of MATRx plus for some time now, I am very pleased with both the patient acceptance and the results in my practice. I have found it easy to introduce to my patients and many have willingly accepted the additional theragnostic testing. Our results have been very good to date with responders proceeding immediately to oral appliances and non-responders returning to trial CPAP, knowing they have taken oral appliances off the table as a best option for them. I look forward to continuing to utilize MATRx plus in my patient work-up and appointment flow."
    Dr. Sharnell Muir, DMD, Diplomate ABDSM, Diplomate ASBASleep Better, Live Better | North Vancouver, BC
  • "For years, when patients or physicians would ask us, 'Will it work for me?' all we could say about mandibular advancement was 'Hope so, we’ll see.' This has kept dental devices from being more useful in the quest to open airways. With MATRx plus in our practice, we can know before we commit to a custom MAD, if this is the best way to treat a patient. Physicians have more confidence in our therapy, patients have more assurance it’s worth their investment. We like being cutting-edge providers, and our patients like doing the tests at home."  
    Dr. Steve Carstensen, DDS & Dr. Carrie Magnuson, DDSPremier Sleep Associates | Bellevue, WA
  • “The predictive value of MATRx plus is huge. Before a sleep apnea patient goes through the process of getting an oral appliance and paying for it, they already know if it’s going to work for them.”
    Dr. Mike Parchewsky, DMDTerra Dental Care | Calgary, AB

How Does it Work?

MATRx plus intelligently guides the feedback controlled mandibular positioner and decides in which direction and by how much to move the patient’s mandible.

MATRx plus is simple to use. Instructional videos guide the patient through sensor set-up and provide tips for a successful study night.


Diagnostic Study

  • Facilitates the diagnosis of OSA
  • Confirms baseline data
  • Supports therapeutic follow-up

Theragnostic Study

  • Identifies OSA patients who will be OAT responders
  • Determines each responder’s effective therapeutic protrusive position

A Digital Workflow Using MATRx plus
for Faster, Effective Sleep Apnea Treatment


Diagnostic Study

• Facilitate initial diagnosis of OSA or to
• Confirm baseline data on a previously diagnosed patient

Theragnostic Study

• Diagnosed OSA patient is fit with MATRx plus titration trays in preparation for study
• Studies are automatically scored and predictions generated for oral appliance response and target protrusive position

3D X-ray Scan

• Scan is performed with MATRx plus trays placed at target protrusive position
• Optical surface scan data of upper and lower jaw is captured within SICAT Air
• Oral appliance is ordered at MATRx plus target protrusive position

Custom Configured Oral Appliance

• Dentist secures MATRx plus trays at target, for use at home, until custom appliance is ready
• Therapeutic follow-up study performed with MATRx plus after appliance fitting
