Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
89 words
A device for taking bite impressions for making partial teeth prosthesis, extensions of prosthesis, crowns and bridges, and the like, comprising: a frame means, curved so as to be substantially parallel to a row of teeth, for disposal in front of the row of teeth for taking bite impressions; and a plurality of elongated bars, detachably coupled to and slidably moveable in said frame means, and radially extending therefrom, having a spherical portion affixed to the free ends thereof for supporting and securing bite impresSion material to the device.
Claim 2
Independent Claim
89 words
A device for taking bite impressions for making partial teeth prosthesis, extensions of prosthesis, crowns and bridges, and the like, comprising: a frame means, curved so as to be substantially parallel to a row of teeth, for disposal in front of the row of teeth for taking bite impressions; and a plurality of elongated bars, detachably coupled to and slidably moveable in said frame means, and radially extending therefrom, having a spherical portion affixed to the free ends thereof for supporting and securing bite impresSion material to the device.
Claim 3
Dependent Claim
66 words
The device as recited in claim 1, wherein said retaining elements are provided with a T-shaped end opposite the end to which said spherical element is affixed, and wherein said frame is provided with a vertically disposed slot extending within the periphery thereof for slidably receiving said T-shaped end and thereby permitting said retaining elements to be slidably positioned along the periphery of said frame means.
Claim 4
Dependent Claim
19 words
The device as recited in claim 1, wherein said frame means and said retaining elements are constructed of plastic.
Claim 5
Dependent Claim
24 words
The device as recited in claim 3, wherein said first and second frame means and said plurality of retaining elements are constructed of plastic.
Claim 6
Independent Claim
156 words
A device for taking bite impressions for making partial teeth prosthesis, extensions of prosthesis, crowns and bridges and the like, comprising: a first frame means, curved so as to be substantially parallel to a row of teeth, for disposal in front of the row of teeth for taking bite impressions; second frame means, curved so as to be substantially parallel to said first frame means, for disposal at the distal end of the row of teeth, said first and second frame means being arranged parallel to and in one plane with respect to each other; a plurality of rigid members affixed to and connecting the free ends of said first and second frame means; and a plurality of detachable, crescent-shaped retaining members, detachably affixed at each end to said first and second frame means, and extending radially therefrom, for supporting and securing the bite impression material between said first and second frame means on the device.
Claim 7
Independent Claim
156 words
A device for taking bite impressions for making partial teeth prosthesis, extensions of prosthesis, crowns and bridges and the like, comprising: a first frame means, curved so as to be substantially parallel to a row of teeth, for disposal in front of the row of teeth for taking bite impressions; second frame means, curved so as to be substantially parallel to said first frame means, for disposal at the distal end of the row of teeth, said first and second frame means being arranged parallel to and in one plane with respect to each other; a plurality of rigid members affixed to and connecting the free ends of said first and second frame means; and a plurality of detachable, crescent-shaped retaining members, detachably affixed at each end to said first and second frame means, and extending radially therefrom, for supporting and securing the bite impression material between said first and second frame means on the device.
Claim 8
Independent Claim
115 words
A device for taking bite impressions for making partial teeth prosthesis, extension of prosthesis, crowns and bridges, and the like, comprising; a first frame means, curved so as to be substantially parallel to a row of teeth for disposal in front of the row of teeth for taking bite impressions, and a plurality of inwardly projecting bar-like elements spaced apart and detachably coupled to said frame means, said bars approximately equal in number to the teeth in a row for supporting and securing bite impressionable material, so that selected ones of said bars corresponding to remaining teeth in a row are broken away leaving the remaining inwardly extending bars for supporting the bite impressionable material.
