Denture Marking
Definition
The technique of embedding a ante-mortem rugae record (cast or photograph) within a dental prosthesis so that the appliance can be matched to ante-mortem records in a mass-casualty or long-term identification scenario.
- Purpose
- Embed identifiable record in a dental prosthesis
- Record embedded
- Cast or photograph of palatal rugae
- Typical scenario
- Mass-casualty or long-term missing-person cases
- Related technique
- Palatal rugoscopy
Common questions
Why mark a denture rather than rely on the wearer's dental records alone?+
A denture wearer has few or no natural teeth left, so conventional dental charting has little to compare. A marking embedded in the prosthesis itself gives postmortem examiners a direct reference point that survives even when the body is severely decomposed or fragmented.
Is denture marking a routine practice or a specialised measure?+
It is not routine; it is typically recommended for individuals at elevated risk of unidentified death or disaster involvement, and depends on the wearer or a dental practice choosing to implement it in advance.
