Claims Analysis
Total Claims: 20
Claim 1
Independent Claim
151 words
A dental disc holder for supporting at least one generally planar dental disc having a centrally located aperture therethrough for pick-up by the circumferentially grooved tip of a longitudinally slotted, radially flexible spindle end of a dental instrument, said holder comprising: body means for holding at least one dental disc, said body means having an upper surface; at least one blind recess formed in said upper surface for retaining a dental disc, each recess having a depth sufficient to retain only one dental disc below said upper surface; each blind recess including means for preventing substantial movement of a retained said dental disc downwardly into the recess when a said spindle end is force-fit into the aperture; and each recess further including means for permitting a said spindle tip to extend beneath the plane of the retained dental disc at least sufficiently to align the plane with the circumferentially grooved tip.
Claim 2
Dependent Claim
151 words
A dental disc holder for supporting at least one generally planar dental disc having a centrally located aperture therethrough for pick-up by the circumferentially grooved tip of a longitudinally slotted, radially flexible spindle end of a dental instrument, said holder comprising: body means for holding at least one dental disc, said body means having an upper surface; at least one blind recess formed in said upper surface for retaining a dental disc, each recess having a depth sufficient to retain only one dental disc below said upper surface; each blind recess including means for preventing substantial movement of a retained said dental disc downwardly into the recess when a said spindle end is force-fit into the aperture; and each recess further including means for permitting a said spindle tip to extend beneath the plane of the retained dental disc at least sufficiently to align the plane with the circumferentially grooved tip.
Claim 3
Dependent Claim
36 words
The holder of claim 1 wherein said means for preventing substantial movement comprises each recess having a substantially flat, rigid bottom surface, and said means for permitting comprises a blind socket in each recess bottom surface.
Claim 4
Dependent Claim
26 words
The holder of claim 2 wherein said at least one recess comprises a plurality of similar recesses spaced laterally adjacent one another in said upper surface.
Claim 5
Dependent Claim
45 words
