The present invention is a method of making a dental impression, having the first step of providing an impression tray filled with a first high viscosity impression material. The second step is to take a first impression by inserting the tray into the patients mouth over a prepared tooth for the patient to bite and let cure. Thirdly, the tray is removed and a second low viscosity impression material is applied over the prepared tooth. The tray is then reinserted into the mouth over the prepared tooth of the patient in order to take a second impression of the prepared tooth, allowing the hydraulic pressure created by the second impression material to urge the sulcus away from the tooth margin. At this point, the tray is removed from the patients mouth.
