(62.78° C.) to a plasticized nonsticky condition deformable into intimate detailed contact with such tooth occlusal surfaces and quickly hardenable by cooling to durable rigid hard strong condition, dimensionally stable for preserving accurately the shape of the print of such tooth occlusal surfaces, and a tray of hard strong material which is not softenable at such softening temperatures of the said curved pad, having one side overlaid by said pad and without a pad overlying its opposite side, said curved pad having a thickness a minor portion of its radial width and providing an exposed principal face for reception of a print of substantially only the dental arch tooth occlusal surfaces.

Claim 4

A composite pallet for recording a print of dental arch tooth occlusal surfaces comprising a curved generally planar pad of thermoplastic material softenable by warming to a temperature of about 145° F. (62.78° C.) to a plasticized nonsticky condition deformable into intimate detailed contact with such tooth occlusal surfaces and quickly hardenable by cooling to durable rigid hard strong condition, dimensionally stable for preserving accurately the shape of the print of such tooth occlusal surfaces, and a tray of hard strong material which is not softenable at such softening temperatures of the said curved pad, having one side overlaid by said pad and without a pad overlying its opposite side, said curved pad having a thickness a minor portion of its radial width and providing an exposed principal face for reception of a print of substantially only the dental arch tooth occlusal surfaces.

Claim 5

A composite pallet recording of a print of dental arch tooth occlusal surfaces comprising a pad of thermoplastic material softenable by warming to a temperature of about 145° F. (62.78° C.) and quickly hardenable by cooling to durable rigid hard strong condition, dimensionally stable for preserving accurately the shape of the print of such tooth occlusal surfaces, and a tray having one side overlaid by said pad to provide an exposed principal face which bears a print of substantially only tooth dental arch occlusal surfaces having tooth print depressions and without a pad overlying the opposite side of said tray, the maximum depth of the tooth imprint depression in such principal face not appreciably exceeding twice the maximum depth of the occlusal surface depressions.

Claim 6

A composite pallet recording of a print of dental arch tooth occlusal surfaces comprising a pad of thermoplastic material softenable by warming to a temperature of about 145° F. (62.78° C.) and quickly hardenable by cooling to durable rigid hard strong condition, dimensionally stable for preserving accurately the shape of the print of such tooth occlusal surfaces, and a tray having one side overlaid by said pad to provide an exposed principal face which bears a print of substantially only tooth dental arch occlusal surfaces having tooth print depressions and without a pad overlying the opposite side of said tray, the maximum depth of the tooth imprint depression in such principal face not appreciably exceeding twice the maximum depth of the occlusal surface depressions.

Claim 7

A process for recording a print of dental arch tooth occlusal surfaces on a pad of thermoplastic material softenable by warming to a temperture of about 145° F. (62.78° C.) and hardenable by cooling, which pad overlies a rigid tray of hard strong material which is not softenable at such softening temperature of the pad to form a pallet having an exposed principal print-receiving surface, which process comprises warming the pallet and thereby softening the pad material but not the tray material, inserting the pallet into a person's mouth, stamping the dental arch tooth occlusal surface on the exposed principal print-receiving surface and thereby producing a print of substantially only dental arch tooth occlusal surfaces having tooth print depressions with the maximum depth of the stamped imprint not appreciably exceeding twice the maximum depth of the tooth occlusal surface imprint depressions, removing the print-bearing pallet from the mouth, and cooling the pallet to harden the thermoplastic material of the pad to durable rigid hard strong condition dimensionally stable for preserving accurately the shape of the print of such tooth occlusal surfaces for indentification information-registering purposes.

Claim 8

A process for recording a print of dental arch tooth occlusal surfaces on a pad of thermoplastic material softenable by warming to a temperture of about 145° F. (62.78° C.) and hardenable by cooling, which pad overlies a rigid tray of hard strong material which is not softenable at such softening temperature of the pad to form a pallet having an exposed principal print-receiving surface, which process comprises warming the pallet and thereby softening the pad material but not the tray material, inserting the pallet into a person's mouth, stamping the dental arch tooth occlusal surface on the exposed principal print-receiving surface and thereby producing a print of substantially only dental arch tooth occlusal surfaces having tooth print depressions with the maximum depth of the stamped imprint not appreciably exceeding twice the maximum depth of the tooth occlusal surface imprint depressions, removing the print-bearing pallet from the mouth, and cooling the pallet to harden the thermoplastic material of the pad to durable rigid hard strong condition dimensionally stable for preserving accurately the shape of the print of such tooth occlusal surfaces for indentification information-registering purposes.

Claim 9

A composite pallet for recording a print of dental arch tooth occlusal surfaces comprising a pad of thermoplastic material softenable by warming to a temperature of about 145° F. (62.78° C.) to a plasticized nonsticky condition deformable into intimate detailed contact with such tooth occlusal surfaces and quickly hardenable by cooling to durable rigid hard strong condition, dimensionally stable for preserving accurately the shape of the print of such tooth occlusal surfaces, and a tray of hard strong material which is not softenable at such softening temperature of said pad having a thickness approximately twice as great as the thickness of the tray and providing an exposed pincipal face for reception of a print of substantially only the dental arch tooth occlusal surfaces.
