Comparison; two functional impression; distal-extension; RPDs
A widely accepted axiom of removable partial prosthodontics is that the prosthesis should be
designed and constructed to preserve the oral structures as well as to restore function. In
distal-extension removable partial dentures, support is derived from a combination of
relatively rigid teeth, the resilient mucosa, and the underlying bone. Dual-impression
techniques have been used to equalize, as much as possible, the support derived from the
edentulous ridges and from the abutment teeth. The need for a physiologic or functional
impression that registers the ridges in their functional form was recognized by McLean. He
described a dual-impression technique whereby a functional impression of the distalextension ridges was made under closing pressure with a custom tray, and then a
hydrocolloid impression was made with the first impression held in position with finger
pressure to register the remainder of the arch.
