Since the discovery of making impression for fixed protheses directly in the mouth, impresions material or negative form resembling the tooth and surrounding structures are used to get a working model. Impression received must be a real replica of a tooth that has been prepared. The impressions that are not clear between the borders with gingival preparation are the common cause of failure when impression was made. Good impression is one of the supporting factors to produce a fixed protheses which can well adapted to the tooth tissue that does not cause leaks and dissolve the cement. So the tooth is protected from caries and the fixed denture can have a better function, durable and good aesthetic. These problems can be overcome by performing gingival retraction on abutment teeth that have been prepared. Gingival retraction can be done mechanically, chemically on prepared abutment teeth by using gingival cord or paste, and by using electrosurgery.
