The functional bilaminar impression technique for the distal extension removable partial denture

In recent years, many clinicians have abandoned the time-consuming and technique-sensitive border-molded custom impression in favor of a simplified stock tray and irreversible hydrocolloid final impression. However, the master cast obtained by this simplified method often will lead to a completed prosthesis that has inadequate support from the distal extension tissue areas. This article presents a simple, predictable, clinically effective, and readily learned functional bilaminar impression technique that will allow dentists to make an anatomically and functionally supported distal extension removable partial denture.
