These are the steps required for taking a final impression.

Fill the impression tray with an elastomeric material aka. Polyvinyl siloxane tray type (Affinis)
Pass the operator the tray filled w/ heavy bodied Affinis.
Leave in pt mouth following manufacturers instructions.
Impression is reviewed by operator, disinfected, and sent to the laboratory with a lab slip.
This is the information that must be included on a lab slip.
