CONNECTING THE MANDIBULAR POSITIONER (MP)
Once the Titration Trays have been fit to the patient with impressions (see
Preparing for an OA Study: Tray
Preparation and Fitting
), they should be attached to the MP prior to dispensing the system to the patient.

Slide the Upper Tray’s Mounting Bracket into the Lower Tray’s
Guide Rails.
Ensure both trays slide back and forth easily.
Hold the MP with the cable facing down.
Hold the set of trays with the scale facing up.
Push the trays onto the rods of the MP.
Connecting the Titration Trays to the MP
Note
Each rod and the corresponding tray’s attachment point are uniquely
shaped to ensure correct orientation during connection (i.e. the Upper
Tray will only attach to the upper rod and the Lower Tray will only
attach to the lower rod).
6.
To secure the tray’s connection to the MP’s rods, use the Tray
Attachment Pins provided.
Figure 21 – Tray Attachment Pins
Note
The two-piece Tray Attachment Pin has a push/pull rivet design. When
the internal pin is inserted into the outer pin sleeve, the rivets of the pin
sleeve expand outward producing a secure grip within the hole.

Ensure the attachment holes on the trays are lined up with the
attachment holes on the rods of the MP.
Pull the internal pins out from their pin sleeves.
Insert each of the pin sleeves through the attachment holes
until the ends of the sleeves are flush against the mounting
brackets on the Upper and Lower Trays.
Push each of the internal pins through each of the pin sleeves
until the pin head is flush and the end of the sleeve is flared.
You may hear a “snap” when the pin is inserted correctly.
Note
Prior to dispensing the MATRx plus System to a patient, ensure the trays
are connected to the MP.
