- Abstract
Gingival retraction is the deflection of marginal gingiva away from the tooth to create sufficient lateral and vertical space between the margins of the tooth preparation and the gingival tissue to allow the injection of adequate bulk of impression material into the expanded crevice. The aim of this review is to analyze the importance of conventional and modern gingival retraction systems in fixed partial denture and to emphasize the importance of gingival retraction for appropriate impression of the deflection of marginal gingiva away from the tooth. The final impression for fixed partial denture fabrication must correctly record the prepared cervical finish line to enable adequate marginal integrity for the restoration. Therefore, proper gingival retraction method is necessary for obtaining an accurate impression for the fabrication of fixed partial denture, particularly when the finish line is equigingival or subgingival.
