You must find the correct VD before recording CR.
Separate the tray posteriors to avoid interference when measuring VD.
• Look at the side or bottom of the tray to see where the separation line is.
• Cut through the impression with a surgical blade at the separation line.
Remove impression overflow on cameo side.

Attach center pin to mandibular tray.
• Cut the bottom portion of the center pin if it

4. Centric Relations (CR)
Accurate CR recording is essential to accurate denture setup.
Prepare for CR recording: Attach Pala Tracer to maxillary tray.
EZ-Tracer
• If the EZ-Tracer is not available, apply tracing material or magic
marker on the maxillary tray bottom for CR tracing.

• Position your finger to where the patient should move their jaw. Instruct the patient to

B Move mandible from the most posterior center position laterally to the right.

C Move mandible from the most posterior center position laterally to the left. Move the mandible back to the posterior center position.
Repeat Steps A–C several times
to trace a precise arrow that points
to the posterior center position on the upper tray.

• Stand behind the patient to hold their jaw in the most posterior position while they bite
down multiple times.
• The center pin should mark a series of points at the posterior of the EZ-Tracer as the
patient bites down.

5. Bite Registration
VERY IMPORTANT: Hold the lower tray firmly in place while recording
bite registration to prevent slipping or tilting.
1. Seat trays back in the mouth. Make sure the center pin locks into the CR point dimple.
2. Inject bite registration material between the trays to record.
• Once the bite registration material hardens, remove the trays from the patient’s mouth.
Very Important
Using the lip ruler, measure the upper lip length from the incisive papilla to upper lip line.
• View the lip ruler straight on for correct measurement. Viewing the ruler from an upward
or downward angle will show an inaccurate measurement.
Finished! You’re all done with the impression visit.
1. Place your denture order online at www.paladigitaldentures.com
or with your Pala Digital Laboratory Partner.
2. Package, label and ship the impression parts (including detached
posteriors) and the printed denture order form your Pala Digital Laboratory.
