What is MATRx?

MATRx is a remote-controlled, oral appliance titration study performed in the sleep lab that produces results enabling physicians to confidently prescribe oral appliance therapy that will be efficacious. A MATRx test confirms whether an OSA patient will be successfully treated with an oral appliance. And, it accurately identifies the target protrusive position that will provide effective oral appliance therapy. MATRx is widely compatible with all types of PSG systems and has been installed in sleep labs across the US and Canada.

The Power of the OATRx Technology

The software that powers the MATRx mandibular titration is known as OATRx TS. It is a scientifically validated and proprietary technology that is revolutionizing patient selection and treatment with oral appliance therapy. The software enables mandibular advancement and determines the OATRx Number also known as the patient’s therapeutic target protrusive position.

How MATRx Works


The MATRx Tray Fitting

  • The sleep physician refers the patient to a sleep dentist
  • The patient’s temporary MATRx titration trays are fit
  • The patient’s mandibular range of motion is provided to the sleep lab


The MATRx Titration Study

  • The sleep technologist conducts the MATRx study
  • The patient’s MATRx titration trays are remotely controlled from the control room
  • The mandible is protruded to eliminate apneas and hypopneas


Physician Interprets the MATRx Study

  • The sleep physician determines if the patient is a responder or a non-responder to mandibular advancement
  • OAT is prescribed for those patients who are responders, including the patient’s target protrusive position



Sleep Dentist & The Oral Appliance

  • The patient returns to the sleep dentist to have their therapeutic oral appliance fabricated and fit
  • The sleep dentist ensures the custom oral appliance is set to a mandibular position that will result in successful therapy
  • Follow-up appointments are scheduled to ensure compliance with therapy
