ABSTRACT:
A method and article for providing identification means, comprising taking an impression of teeth with a thermoplastic wafer of special configuration such that the wafer receives an impression which gives the size, shape and anatomy of each tooth from the occlusal surface to the gum line, and also provides information on tooth position and jaw relationship, to provide maximum information for identification. The wafer also acquires salivary components which, for an indeterminate amount of time, allows for DNA analysis testing or scent dog tracing. The wafer with the impression is then stored for use in case of need, preferably in a container which is sealed so that tampering with the contents can be detected.
