A method of forming a dental impression in two steps comprises first applying a light-curable impression material to a portion of the oral cavity of interest to form an initial impression and exposing said impression material to a source of activating light to at least partially set said impression material, and then applying a chemically-curing impression material over the light-cured impression material and allowing said chemically-curing impression material to set and bond with the light-cured material, before finally removing the resulting composite impression from the oral cavity. |
