    摘要: Dental impressions are formed without retraction of the gingival tissue by injecting impression material from a syringe having a flexible tubular member positioned over the prepared tooth. The tubular member has a diameter corresponding to the size of the tooth and a tip contoured to the approximate shape of the gingival margin. The tubular member is initially positioned with the contoured tip extending into the gingival sulcus. As the impression material is injected around the tooth the tubular member is slowly withdrawn so that the tooth is fully covered with impression material extending completely into the gingival crevice. A full arch impression tray is then positioned within the mouth of the patient and the impression material allowed to harden.

    摘要: Method and means for obtaining a dental impression of a reduced tooth for jacket crown, bridgework and like constructions, comprising the use of an impression tube which is substantially inflexible at least longitudinally and which is attached to a syringe for supply of impression material when placed about a tooth and which has a distal end provided with a contour corresponding to the gingival margin at said tooth by the scribing on said tube of a line substantially parallel to the gingival margin, and subsequently removing the end portion of the tube beyond said line.
