Abstract
Abstract A method and apparatus for identification of persons using dental data is disclosed. A unique but simple bite wafer is inserted between the lower and upper jaws of a person and biting pressure is exerted on the wafer. The registrations made on the bite wafer are geometrically evaluated. The geometric data is permanently recorded for future use when identifications and/or comparisons are to be made. The recorded data is different for each person which enables the identification and comparisons.

Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
63 words
Apparatus for making a bitemark registration of a person's upper or lower teeth comprising at least one wafer of a recording material capable of being slightly compressed by normal biting forces, one wafer of a transferring material capable of transferring said bitemark registration onto said recording material wafer, with said transferring material wafer being placed against one side of said recording material wafer.
Claim 2
Dependent Claim
63 words
Apparatus for making a bitemark registration of a person's upper or lower teeth comprising at least one wafer of a recording material capable of being slightly compressed by normal biting forces, one wafer of a transferring material capable of transferring said bitemark registration onto said recording material wafer, with said transferring material wafer being placed against one side of said recording material wafer.
Claim 3
Dependent Claim
12 words
The apparatus of claim 1, wherein said recording material wafer comprises cardboard.
Claim 4
Dependent Claim

Claim 7
Dependent Claim
99 words
Apparatus for making a bitemark registration of a person's upper and lower teeth comprising two wafers of a recording material capable of being slightly compressed by normal biting forces, two wafers of a transferring material capable of transferring the registration of a person's teeth onto said recording material wafer, with one of said transferring material wafers being placed against one side of one of said recording material wafers and the other transferring material wafer being placed against one side of the other side of said recording material wafers, said recording material wafers being interposed between said transferring material wafers.
Claim 8
Dependent Claim
99 words
Apparatus for making a bitemark registration of a person's upper and lower teeth comprising two wafers of a recording material capable of being slightly compressed by normal biting forces, two wafers of a transferring material capable of transferring the registration of a person's teeth onto said recording material wafer, with one of said transferring material wafers being placed against one side of one of said recording material wafers and the other transferring material wafer being placed against one side of the other side of said recording material wafers, said recording material wafers being interposed between said transferring material wafers.
Claim 9

Claim 12
Dependent Claim
15 words
The apparatus of claim 6, wherein said wafers are hermetically sealed by a plastic covering.
Claim 13
Independent Claim
88 words
A method for establishing a record enabling the identification of persons comprising the steps of making a bitemark registration of one of a person's upper or lower teeth on bitemark registration apparatus; for one of the lateral arch halves of said bitemark registration, determining the slope of the line connecting the two most spaced apart premolars and molars; determining the angle between said line between the molars and the line substantially bisecting the bitemark registration into the two lateral arch halves; and, recording the slope and the angle.
Claim 14
Independent Claim
88 words
A method for establishing a record enabling the identification of persons comprising the steps of making a bitemark registration of one of a person's upper or lower teeth on bitemark registration apparatus; for one of the lateral arch halves of said bitemark registration, determining the slope of the line connecting the two most spaced apart premolars and molars; determining the angle between said line between the molars and the line substantially bisecting the bitemark registration into the two lateral arch halves; and, recording the slope and the angle.
Claim 15
Dependent Claim
35 words
The method of claim 1, including the steps of determining the slope and the angle between the line bisecting the lateral arch halves for the other lateral arch half and recording said slope and angle.
Claim 16
Dependent Claim
27 words
The method of claim 12, including the steps of determining the angle between the lines connecting the molars on each lateral arch half and recording said angle.
Claim 17
Dependent Claim
77 words
The method of claim 13, including the steps of making a registration of the other of said person's upper or lower teeth on bitemark registration apparatus, determining the slopes of the lines connecting the two most spaced apart premolars and molars, determining the angles between said slope lines and the line bisecting each lateral arch half of said other bitemark registration, determining the angle between the slope lines of said other bitemark registration, and recording said data.
Claim 18
Dependent Claim
21 words
The method of claim 1, including the steps of determining the location of a person's missing teeth and recording said locations.
Claim 19
Dependent Claim
18 words
The method of claim 1, including the steps of recording said person's date of birth, sex and name.
