Title: ONE STEP GINGIVA RETRACTION AND IMPRESSION MATERIAL AND METHOD
Abstract:
A dental retraction and impression system providing self-retracting and impression taking of a prepared tooth in one step. Paired setting materials simultaneously retract gingiva, widen a sulcus around the tooth, and take an impression of the tooth and margins. A low viscosity setting gingival retracting impression material having an astringent and a high viscosity setting impression material set together. The high viscosity setting impression material is heavy body and has a higher viscosity than the low viscosity setting gingival retracting material so as to force the low viscosity setting gingival retracting impression material into the gingival space or sulcus.
