Abstract
Fixed dental prosthesis success requires appropriate impression taking of the prepared finish line. This is critical in either tooth supported fixed prosthesis (crown and bridge) or implant supported fixed prosthesis (solid abutment). If the prepared finish line is adjacent to the gingival sulcus, gingival retraction techniques should be used to decrease the marginal discrepancy among the restoration and the prepared abutment. Accurate marginal positioning of the restoration in the prepared finish line of the abutment is required for therapeutic, preventive and aesthetic purposes.1This article discusses the current methods that are applied for displacement of gingival tissues so that adequate amount of unprepared tooth structure can be recorded with least distortion of impression material as well as minimal damage to attachment apparatus of the tooth.2
