A dental impression pad is used with a dental tray for making an impression of a patient's teeth. Dental impression material, which becomes moldable when heated, is placed on one side of a strip of Mylar TM material. The other side of the strip is covered with adhesive attaching the strip the dental tray. The dental impression pad also includes a protective sheet mounted to cover and protect the adhesive until use. When the pad is used, the protective sheet is peeled away to expose the adhesive. Dental impression pads are made by applying adhesive and a protective sheet to backing strips; melting a dental impression material; dripping or placing the dental impression material on the backing strips; shaping the dental impression material to the form desired; and cooling the impression material to a hardened state. |
