Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
100 words
A bite registration device for introducing bite registration material between the occlusal surfaces of teeth comprising a non-woven sheet of foraminous film having on each of its surfaces an adhesive material for holding a wax, said film being perforated over the major portion of its surfaces providing a septal distance between perforations so small that the material of said film between perforations is readily frangible under occlusal pressure on a registration material carried by said film so that it substantially lacks the ability to stimulate the proprioceptors associated with the teeth of which an occlusal impression is to be taken.
Claim 2
Dependent Claim
100 words
A bite registration device for introducing bite registration material between the occlusal surfaces of teeth comprising a non-woven sheet of foraminous film having on each of its surfaces an adhesive material for holding a wax, said film being perforated over the major portion of its surfaces providing a septal distance between perforations so small that the material of said film between perforations is readily frangible under occlusal pressure on a registration material carried by said film so that it substantially lacks the ability to stimulate the proprioceptors associated with the teeth of which an occlusal impression is to be taken.
Claim 3
Dependent Claim
14 words
A device according to claim 1 having a wax on each of said surfaces.
Claim 4
Dependent Claim
16 words
A device according to claim 2 including a protective cover for storing the device until used.
Claim 5
Dependent Claim
18 words
A device according to claim 1 wherein said film is perforated over more than one-half of its surface.
Claim 6
Dependent Claim
27 words
The device according to claim 1 in combination with a bite registration material on both surfaces of said film and joined through the perforations in said film.
Claim 7
Dependent Claim
13 words
A device according to claim 1 including frame means peripherally supporting said film.
Claim 8
Dependent Claim
78 words
A device according to claim 6 for full-dental-arch use wherein said frame means is shaped to the outer periphery of a full arch and to the inner periphery of the posterior lateral teeth in both quadrants, and said film is generally U-shaped spanning the frame means at said quadrants and extending from said frame means at the anterior part of said outer periphery toward said frame means at said inner periphery in the region of the anterior teeth.
Claim 9
Dependent Claim
21 words
A device according to claim 1 wherein said carrier is made of a material selected from plastics, paper and metal films.
