The motor, which is housed inside the MATRx Mandibular Positioner is NOT placed in the patient’s mouth; only the temporary, custom-fitted MATRx Titration Trays. The trays are attached to the mandibular positioner by mounting brackets extending from the front of the trays. The trays are comfortable and the patient is unaware of the attached light-weight mandibular positioner.
No. The MATRx titration procedure is very similar to that used for CPAP titrations. Installation and on-site training are included in the price of the product. In addition, every MATRx lab has access to resource documents and manuals that review the titration procedure. Our technical support representatives are also available 24/7 and can be contacted by phone or via email.
Yes. Please refer to the MATRx Clinical Applications Guide for a review of the interpretive criteria and case study examples.
Given the high predictive accuracy of a MATRx study, follow-up testing is not usually required. However, in situations where follow-up testing is determined to be appropriate, a polysomnographic study is the gold standard. When a polysomnographic study is not available, an AASM compliant portable sleep recorder can be used.
Yes, the temporary titration trays can be fit by a sleep tech that has been trained by a sleep dentist to perform tray fitting.
Cleaning procedures for the MATRx system are included in the User Manual and follow standard cleaning procedures approved for use in Sleep Laboratories.
Titration trays: are for single patient multi-use for one study only; please refer to your User Manual for tray cleaning instructions before and after taking impressions. Reuse of the trays for more than one study may compromise the system’s accuracy.
Mandibular Positioner (motor) and cables: can be reused between patients; please refer to your User Manual for pre-cleaning, cleaning and disinfection procedures.
The motor is NOT placed in the patient’s mouth; only the trays. The trays are attached to mounting brackets extending from the front of the trays to the motor outside of the patient’s mouth. The custom-fitted dental titration trays are comfortable and the patient is unaware of the light-weight motor attached to the trays.
To date, the device has been well tolerated by patients involved in MATRx clinical studies. The quiet, small incremental movements associated with a MATRx titration rarely cause EEG arousal or changes in sleep state.
Yes, the AASM standards require the use of a nasal pressure cannula and an oro-nasal thermocouple device.
This is called the patient’s target protrusive position (i.e. OATRx Number). Your patient has reached this therapeutic “target” when you observe a clean window of REM sleep in the supine position (i.e. less than 2 apneas and or hypopneas during this period). Please refer to the MATRx Clinical Applications Guide to review the titration protocol and other important clinical considerations when conducting a MATRx study.
The OATRx number is the minimum protrusive position at which the sleep physician feels confident that patient will receive effective oral appliance therapy based on application of the MATRx interpretive criteria.
To determine the OATRx number (i.e. target protrusive position) from the MATRx study data, the sleep physician should review the full night of study data and evaluate the patient’s response to mandibular titration during REM and NREM sleep and in both the supine and lateral positions. This is similar to the review performed when determining a patient’s CPAP prescription following a CPAP titration.
For more information, please refer to the case study section of the MATRx Clinical Applications Guide.
The MATRx study offers a high degree of predictive accuracy (i.e. which patients will or will not be successful with oral appliance therapy) and also provides the sleep dentist with a target protrusive position that will result in the efficacious therapy. This means that the sleep dentist should be able to treat more patients, more effectively and in less time.
In many cases, the patient’s mandible can be moved immediately to the prescribed target protrusive position (TPP) eliminating the need for multiple office visits.

This is the mandibular protrusive position that will result in effective treatment of the patient’s OSA with a custom oral appliance (mandibular repositioning appliance). The sleep physician determines the patient’s target protrusive position, also known as the OATRx Number, when performing the MATRx study interpretation. The sleep dentist will use the target protrusive position to fabricate the patient’s custom oral appliance to their therapeutic position.
In the most recent clinical study (n=67) the efficacy of the MATRx target protrusion position was 93% in patients correctly predicted to be therapeutically successful.
The vertical separation is 3-4mm, depending on the amount of bite registration material used.
Currently, use of the MATRx system is contraindicated in patients who are not able to breathe comfortably through their nose during sleep.
The MATRx trays have been designed for use with Henry Schein Blu-Bite HP Fast Set only, which sets in approximately 20-30 seconds.
There are 2 conversion methods available.
Please consult Converting the OATRx Number for Appliance Fabrication.
No. At the initial visit you will need to perform an oral exam to determine if the patient is a suitable candidate for an oral appliance. Once candidacy is confirmed, you will: 1) fit the patient’s ’s MATRx titration trays 2) prepare impressions to customize the patient’s bite within the trays and ensure adequate tray retention 3) record the patient’s scale readings (i.e. this will be the range of motion used by the sleep tech when conducting the MATRx study).
Yes, most dental labs should accept the MATRx trays as the bite registration however you should contact the lab fabricating your appliances to confirm this change in practice is understood and accepted.
