The purpose of the study was to use a simplified impression technique, which is an alternative to the conventional method for complete denture fabrication. This was introduced to reduce the number of patient visits, operator time, as well as to compare the efficacy of a simplified impression technique (single appointment impression) with the conventional method (two appointments – primary and final impression).
An impression is a record of mouth tissues taken at an unstrained rest position or in various positions of displacement.1 The impression stage of constructing complete dentures is to design the denture bases to the optimum denture-supporting area and to ensure that the border form of the prostheses provides a functional peripheral seal. It is generally agreed by the British Society of Prosthodontics (BSSPD) in their guidelines that meeting these objectives achieves denture stability and retention, and enables effective function.2 Many different concepts and approaches have been described to achieve these goals, along with specific materials and techniques by which the given objectives might be accomplished. Even though there are wide variations in individual preferences for a particular material or method, most US dental schools believe that, for a successful outcome, a two-appointment (primary and final impression) procedure is required.3 However, there is a lack of strong evidence as to whether one material is superior or a particular technique would produce better long-term results in terms of complete denture performance.4
