Histological Observation of a Cremated Mandible with an Inserted Blade Implant

Abstract

The implant often used by dentists as a substitute for lost teeth takes on,when subjected to heating,a color, which is considerably different from that seen in untreated or normal specimens.Unless dentists pay attention to this fact, it may lead to grave blunders when special cases are encountered. We observed one such case and obtained results therefrom, which are summarized below.
1. The metal constituting the implant changes appearance when heated.
2. An oxide membrane, white in color, consisting of TiO₂ and covering the surface of the metal substrate is formed through cremation.
3. As far as can be determined from color changes of the oxide membrane covering the implant body, the cadaver was subjected to cremation at 800～850℃ for 60～180 minutes.
