Personal identification using dental prostheses.

A personal identity mark may be added to a metal or an acrylic resin prosthesis. The importance of this technique, particularly in terms of forensic investigation and identification, should make it a compulsory dental procedure. Where metal is involved, engraving is the most desirable method of marking. The heat resistance of various labeling materials indicates that an acrylic resin prosthesis should contain a marked, heat resistant material together with a mark clearly visible from the denture surface.
