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.
Claims19
A wafer for taking a simultaneous impression of upper and lower teeth, comprising:
- upper and lower surfaces of impressionable thermoplastic material that softens when warmed,
- the wafer having a pair of laterally spaced portions to receive the impression of the molars and being thick enough to record the shape of the molars from the biting surface substantially to the gum line, and an anterior portion extending between the posterior portions and positioned to receive an impression of the front teeth from the biting edge substantially to the gum line,
- the wafer further including an absorbent material coupled to the wafer along a side of the wafer for capturing cells from the cheek and also for capturing saliva.
A wafer for taking a simultaneous impression of upper and lower teeth, comprising:
- upper and lower surfaces of impressionable thermoplastic material that softens when warmed,
- the wafer having a pair of laterally spaced portions to receive the impression of the molars and being thick enough to record the shape of the molars from the biting surface substantially to the gum line, and an anterior portion extending between the posterior portions and positioned to receive an impression of the front teeth from the biting edge substantially to the gum line,
- wherein at least the laterally spaced portions of the wafer comprise enlarged edges that are thicker than the rest of the laterally spaced portions, to stiffen the wafer when it is softened.
