Selective-pressure single impression procedure for tooth-mucosa-supported removable partial dentures.

This article describes a method of making impressions for tooth-mucosa-supported removable partial dentures using a single impression procedure. Through the use of border-molded custom trays, selectively relieved, and application of pressure on residual ridge areas, the objectives of maximum tissue coverage and selective tissue placement of primary stress-bearing areas are fulfilled. With a single impression procedure, treatment time is reduced and laboratory errors commonly encountered with the altered cast impression technique can be minimized or eliminated.
