Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
189 words
A device for securing a removable denture or dental prosthesis to a fixed tooth comprising, in combination; a stationary plate member permanently fastened to a fixed tooth, said plate member containing a generally vertically extending channel having dovetail-shaped side walls and being of a narrowed width in at least the bottom end portion thereof, a horizontal recess extending across said plate member in the upper region thereof; a removable member for supporting the removable denture adapted to slide downwardly within the vertically extending channel in said plate member, said removable member having a configuration essentially corresponding to the dimensions of said channel, said removable member further having a horizontal recess in alignment and coextensive with the recess in said plate member upon positioning of said removable member in said channel; and locking means adapted to slide horizontally in said aligned recesses for positioning therein so as effectively arrange said plate member and said removable member into locked engagement; said plate member, removable member, and said locking means, upon assembly thereof, each having at least one surface portion forming a continuous coplanar surface extending along the exterior of the tooth.
Claim 2
Independent Claim
189 words
A device for securing a removable denture or dental prosthesis to a fixed tooth comprising, in combination; a stationary plate member permanently fastened to a fixed tooth, said plate member containing a generally vertically extending channel having dovetail-shaped side walls and being of a narrowed width in at least the bottom end portion thereof, a horizontal recess extending across said plate member in the upper region thereof; a removable member for supporting the removable denture adapted to slide downwardly within the vertically extending channel in said plate member, said removable member having a configuration essentially corresponding to the dimensions of said channel, said removable member further having a horizontal recess in alignment and coextensive with the recess in said plate member upon positioning of said removable member in said channel; and locking means adapted to slide horizontally in said aligned recesses for positioning therein so as effectively arrange said plate member and said removable member into locked engagement; said plate member, removable member, and said locking means, upon assembly thereof, each having at least one surface portion forming a continuous coplanar surface extending along the exterior of the tooth.
Claim 3
Dependent Claim
46 words
A device as claimed in claim 1, wherein the recesses in said plate member and said removable member comprise a longitudinally tapered channel having dovetail-shaped side walls; said locking means comprising an elongate tapered wedge having a configuration complementary to the dimensions of said tapered channel.
Claim 4
Dependent Claim
54 words
A device as claimed in claim 1, wherein said plate member includes horizontally extending recessed surface portions along the upper edge thereof; said locking means comprising an elongate bar having longitudinally extending projections and grooves adapted to respectively engage the recesses in and edges on said plate and removable members upon lateral engagement therewith.
Claim 5
Dependent Claim
65 words
A device as claimed in claim 1, wherein said plate member includes a horizontally extending recessed frontal surface portion along the upper edge portion thereof, and laterally extending recesses along the side edges; said locking means comprising an elongate bar having laterally extending projections and grooves adapted to respectively engage the recesses in and edges on said plate and removable members upon frontal engagement therewith.
Claim 6
Dependent Claim
18 words
A device as claimed in claim 1, wherein said vertical channel in said plate member is generally V-shaped.
Claim 7
Dependent Claim
32 words
A device as claimed in claim 1, wherein said vertical channel in said plate member is generally rectangularly shaped, and at its lower end extends into a narrower channel of V-shaped configuration.
Claim 8
Dependent Claim
24 words
A device as claimed in claim 1, wherein said fixed tooth comprises a crown or cap, and said plate member is permanently implanted therein.
