SomnoMed MATRx



SomnoMed MATRx is a revolutionary diagnostic system that combines the expertise of a sleep dentist and a sleep physician to identify patients that will benefit from SomnoDent therapy and optimizes their effective protrusive distance. To use this medical diagnostic device, a dentist assesses the patient and fits them with a temporary device which is then titrated in an attended sleep study without disturbing the patient's sleep.

This information concerns a use that has not been approved or cleared by the Food and Drug Administration.

Dental Assessment

To use this assessment tool, dental expertise is required to assess the patient's candidacy for an oral appliance. The sleep dentist fits the patient with a temporary oral appliance, proprietary to SomnoMed MATRx. Using the proprietary scale on the upper and lower Titration Trays, three measurements are taken to characterize the patient's mandibular range of motion:

1) Habitual bite position
2) Maximum voluntary protrusion of the mandible
3) Full retrusion of the mandible..

In-lab Sleep Study

Once the temporary oral appliance is ready the patient proceeds to their local sleep center to undertake an attended polysomnographicsleep study using the SomnoMed MATRx diagnostic system. The temporary oral appliance is then attached to an actuator that is remotely controlled by the sleep technologist while the patient sleeps. This enables the sleep center to progressively protrude the mandible toeliminate respiratory disturbance in a process analogous to an industry standard CPAP titration study.

Clinically Validated

SomnoMed MATRx uses patented technology developed by Zephyr Sleep Technologies Chief Medical Officer, Dr. John Remmers. The technology behind MATRx was studied and published in the American Journal of Respiratory and Critical Care Medicine and the European Respiratory Journal in 2004 and 2006 respectively. These studies found that the technology is highly predictive of AMP (Anterior Mandibular Positioners) response 1 and that the target protrusion determined during the remotely controlled mandibular positioner test was the effective therapeutic protrusion.2
