Abstract
A dental impression package pre-loaded with dental impression material adapted for taking accurate impressions of a patient's teeth and/or gums by professional personnel is provided. The impression material used is flowable to a desired degree and has a viscosity of substantially one million centipoises. Packaging a pre-loaded dental impression tray is accomplished by first quickly immersing the loaded tray in a solution of natural latex for a few seconds and then quickly removing the coated product followed by quickly immersing it in a coagulating solution of acetic acid for a few seconds to stabilize the latex coating; withdrawing the stabilized coated product; drying it; and suitably packaging the product for storage and sale. If the impression material is of a light-curable nature, the packaging is of light-opaque nature.
