Abstract
Abstract An identification plate of gold alloy is inserted in a small blind hole drilled into the crown of a tooth. The hole is then filled with a durable filler which hardens around the plate to embed it in a durable, heat resistant filling. The filling material can be colored so that it is readily located when identification is desired. For making the identification, the filler is dissolved away to leave the plate, which can be read by means of optical magnification. Also disclosed is an electrical device especially adapted for providing plate blanks with the desired identifying information.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
111 words
A method for providing the body of a living person with visually identifiable and locatable permanent identifying information, comprising the steps of: providing a shallow cavity in the surface of a dental crown in the person's mouth, installing in the shallow cavity an information carrier of durable material, the carrier being provided with information as to the identity of the person, and filling the shallow cavity with a filling material which, on at least the surface of the filling material has a coloring which is visually identifiable with respect to the color of the dental crown surface, said filling material embedding the plate and hardening to a durable, heat resistant filling.
Claim 2
Independent Claim
111 words
A method for providing the body of a living person with visually identifiable and locatable permanent identifying information, comprising the steps of: providing a shallow cavity in the surface of a dental crown in the person's mouth, installing in the shallow cavity an information carrier of durable material, the carrier being provided with information as to the identity of the person, and filling the shallow cavity with a filling material which, on at least the surface of the filling material has a coloring which is visually identifiable with respect to the color of the dental crown surface, said filling material embedding the plate and hardening to a durable, heat resistant filling.
