Abstract
Abstract A device for use in attaching artificial teeth to the bone which supports the natural teeth. The device may have an anchoring member comprising a tooth support receiving member, at least one arm extending laterally from the member, means for coupling the arm with the bone and a spike adapted to be lodged into the bone and extending outwardly from the receiving member. In addition to an anchoring member, the device may comprise a tooth support adapted to be removably positioned upon the anchoring member and designed to allow for limited movement of the artificial teeth.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
102 words
A tooth implant device for attachment to the bone which supports the natural teeth, said device comprising: a tooth support receiving member adapted to be positioned on said bone and extend outwardly from the ridge of the bone, said receiving member having an outwardly concave surface constructed for receiving a convex base portion of a tooth support; at least one arm extending in a lateral direction from said member and adjacent at least one side of said bone; means for securing said arm to said bone; and a spike extending outwardly from said member and adapted to be lodged into said bone.
Claim 2
Dependent Claim
102 words
A tooth implant device for attachment to the bone which supports the natural teeth, said device comprising: a tooth support receiving member adapted to be positioned on said bone and extend outwardly from the ridge of the bone, said receiving member having an outwardly concave surface constructed for receiving a convex base portion of a tooth support; at least one arm extending in a lateral direction from said member and adjacent at least one side of said bone; means for securing said arm to said bone; and a spike extending outwardly from said member and adapted to be lodged into said bone.
Claim 3
Dependent Claim
17 words
The device of claim 1, wherein said arm presents an aperture adapted to accommodate said securing means.
Claim 4
Dependent Claim
27 words
The device of claim 1, including a tooth support removably positioned on said member and having a spherical base and a post extending outwardly from said base.
