How is home sleep testing regulated for dental practices? Regulations vary by state or province, please check with your state or provincial healthcare regulators, medical and/ordental associations, and with medical billing providers for the latest information for doctors (dentists and physicians) testing, diagnosing and treating obstructive sleep apnea.

Will my patients find MATRx™ plus easy to use? Yes, we make it easy! MATRx™ plus technology is designed to keep the sleep apnea testing and diagnostic processsimple.

How is the MATRx plus test different than other home sleep apnea tests? Other standard home sleep tests only aid in the diagnosis of obstructive sleep apnea. MATRx plus is a multi-functional device capable of performing both a standard home sleep test and an oral appliance “theragnostic” study – with the auto-titrating mandibular positioning device – which predicts the therapeutic outcome of a customized oral appliance and the target protrusion position.

I already provide oral appliance therapy in my practice, why would I want to use the MATRx™ plus? We know that oral appliance therapy (OAT) doesn’t work for everyone; efficacy of OAT ranges from 50-70%. MATRx plus removes the costly guesswork. A binary prediction of responder or non-responder is provided, along with a target protrusion for the custom-fitted appliance. Knowing who to treat and their target, in advance should increase your oral appliance success rates, decrease the time-to-therapy, and minimize the risk of over-titration.

Will MATRx plus reduce my chair time for oral appliance therapy? Yes. You will eliminate fitting and titrating oral appliances on patients who are determined to be non-responders to oral appliance therapy. For those who are responders, the patient’s mandible, in many cases, can be moved immediately to the prescribed target protrusive position eliminating the need for multiple office visits.

What is the primary benefit of using MATRx plus compared to the conventional approach for fitting and titrating custom oral appliances? The MATRx plus allows the sleep dentist to determine, in advance, which patients will be effectively treated with an oral appliance. It also provides the dentist with a therapeutic target protrusive position prior to fabrication of the custom-fitted oral appliance. This allows the dentist to improve the efficiency of appliance fitting at target, decrease the time-to-therapy and minimize the risk of over-titration.

Will MATRx plus reduce my chair time for oral appliance therapy? Yes. You will eliminate fitting and titrating oral appliances on patients who are identified as non-responders to oral appliance therapy. For those who are responders, the patient’s mandible, in many cases, can be moved immediately to the prescribed target protrusive position. This eliminates the need for multiple office visits.
