Oral Appliance Testing at a Sleep Lab

Predicting Success with Oral Appliance Therapy

Know who to treat and their target

The MATRx system integrates with the polysomnogram to allow monitoring of the patient during a customized dental titration using temporary trays.

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

Oral Appliance Titration Made Simple

Titrate remotely, without disturbing your patient’s sleep, using our proprietary titration software.

Use an evidence-based approach to select patients who are responders to oral appliance therapy.

Confidently prescribe therapy, including the target protrusive position.

  • “(MATRx) might be a promising instrument for predicting OAm treatment outcome and targeting the degree of mandibular advancement needed.”
    Journal of Clinical Sleep Medicine 2016
  • “The MATRx study offers a clear advantage for patients and doctors by eliminating guess work in treating OSA with MRDs. We can quickly and efficiently determine effective treatment parameters with the MATRx as part of our standard treatment protocol.”
    Dr. Srujal Shah, DDS, Diplomate ABDSMSpark Sleep Solutions, San Jose CA
  • “Overall the initial study using (MATRx) shows good accuracy in identifying patients who will be fully treated by (an oral appliance) well as the likely mandibular protrusion level.”
    Orange Registry Update,Journal of Clinical Sleep Medicine 2014

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


MATRx in-lab Study

• Physician selects patient for MATRx study
• Dentist fits MATRx titration trays and identifies mandibular range of motion needed for MATRx study
• Sleep tech inserts MATRx trays, performs titration and scores study

Physician Interprets Study Results

• Physician evaluates the data and determines if the patient is a responder to oral appliance therapy
• A target protrusive position is identified for all responders

3D X-ray Scan

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

Oral Appliance

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