Tremendous progress has been made in procedures for making fixed prosthodontic impressions over the past few decades. A common objective for impressions and interim crowns or fixed dental prostheses is to register the prepared abutments and finish lines accurately. For all impression procedures, the gingival tissue must be displaced to allow the subgingival finish lines to be registered. Retraction is the temporary displacement of the gingival tissue away from the prepared teeth. This 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. In addition to this, gingival displacement techniques around implants and for computer aided design/computer added manufacturing (CAD/CAM) based restorations have been discussed. PubMed and Google Scholar were used to search any studies involving gingival retraction techniques. The keywords used were gingival retraction, gingival displacement, gingival retraction in implants and retraction cord. Gingival retraction holds an indispensable place during soft tissue management before an impression is made. Swift increase in research work in the recent past leaves no option for a clinician, but to be updated and to possess optimum knowledge to rationalize the use of materials and techniques that are employed for gingival displacement in proximity to both teeth as well as implants. |
