Threaded drivable dental implant

Claim 2

A dental implant to be received within a hole drilled into the bone, said dental implant including a lower threaded portion having an axis, and an upper neck portion, said lower threaded portion and said neck portion being coaxial, said lower threaded portion including at least one thread extending throughout said lower threaded portion and including a crest of said thread, said crest of said thread forming an acute angle of no more than 30° with said axis, so that said implant is adapted to be driven into said hole drilled into the bone by forces exerted axially of said implant.

Claim 3

A dental implant as claimed in claim 1, wherein said acute angle is from 20° to 25°.

Claim 4

A dental implant as claimed in claim 1, said at least one thread comprising a multiple thread, the threads of said multiple thread being uniformly spaced around said implant.

Claim 5

A dental implant as claimed in claim 3, said multiple thread comprising four threads.

Claim 6

A dental implant as claimed in claim 1, said implant further including a post carried on said neck portion, the dimensions of said implant being such that said threaded portion will be received within said hole drilled into the bone, said neck portion will extend from said hole to above the gum line, and said post will be disposed above said gum line.

Claim 7

A dental implant as claimed in claim 5, said post defining a threaded recess therein, a screw threadedly receivable within said recess, and locking means for securing said screw within said recess.

Claim 8

A dental implant as claimed in claim 6, said screw defining a bore laterally therethrough, said locking means comprising a deformable rod received within said bore and engageable with the threads in said threaded recess.

Claim 9

A dental implant as claimed in claim 7, wherein said rod consists of a thermoplastic elastomer.

Claim 10

A dental implant, of the type wherein a hole is drilled into the bone for receiving the implant, and the implant carries a post above the gum line for attachment of a prosthesis, said implant including a threaded portion to be received within said hole and having an axis, and a neck portion extending coaxially from said threaded portion through the soft tissue, said threaded portion having a multiple thread extending throughout the length of said threaded portion, each thread of said multiple thread being disposed at an acute angle of no more than 30° with respect to said axis so that said implant can be driven into said hole by forces exerted axially of said implant, the arrangement being such that said implant will rotate somewhat under the influence of said threads as said implant threads into said hole.

Claim 11

A dental implant, of the type wherein a hole is drilled into the bone for receiving the implant, and the implant carries a post above the gum line for attachment of a prosthesis, said implant including a threaded portion to be received within said hole and having an axis, and a neck portion extending coaxially from said threaded portion through the soft tissue, said threaded portion having a multiple thread extending throughout the length of said threaded portion, each thread of said multiple thread being disposed at an acute angle of no more than 30° with respect to said axis so that said implant can be driven into said hole by forces exerted axially of said implant, the arrangement being such that said implant will rotate somewhat under the influence of said threads as said implant threads into said hole.

Claim 12

A dental implant as claimed in claim 9, and further including a post carried on said neck portion, the dimensions of said implant being such that said threaded portion will be received within said hole drilled into the bone, said neck portion will extend from said hole to above the gum line, and said post wall be disposed above said gum line.

Claim 13

A dental implant as claimed in claim 10, said post defining a threaded recess therein, a screw threadedly receivable within said recess, and locking means for securing said screw within said recess.

Claim 14

A dental implant, of the type wherein a hole is drilled into the bone for receiving the implant, and the implant carries a post above the gum line for attachment of a prosthesis, said implant including a threaded portion to be received within said hole, and a neck portion extending coaxially from said threaded portion through the soft tissue, said threaded portion having a multiple thread extending throughout the length of said threaded portion, said multiple thread being at such an angle that said implant can be driven into said hole by forces exerted longitudinally on said implant, the arrangement being such that said implant will rotate somewhat under the influence of said threads as said implant threads into said hole, and further including a post carried on said neck portion, the dimensions of said implant being such that said threaded portion will be received within said hole drilled into the bone, said neck portion will extend from said hole to above the gum line, and said post will be disposed above said gum line, said post defining a threaded recess therein, a screw threadedly receivable within said recess, and locking means for securing said screw within said recess, said screw defining a bore laterally therethrough, said locking means comprising a deformable rod received within said bore and engageable with the threads in said threaded recess.

Claim 15

A dental implant, of the type wherein a hole is drilled into the bone for receiving the implant, and the implant carries a post above the gum line for attachment of a prosthesis, said implant including a threaded portion to be received within said hole, and a neck portion extending coaxially from said threaded portion through the soft tissue, said threaded portion having a multiple thread extending throughout the length of said threaded portion, said multiple thread being at such an angle that said implant can be driven into said hole by forces exerted longitudinally on said implant, the arrangement being such that said implant will rotate somewhat under the influence of said threads as said implant threads into said hole, and further including a post carried on said neck portion, the dimensions of said implant being such that said threaded portion will be received within said hole drilled into the bone, said neck portion will extend from said hole to above the gum line, and said post will be disposed above said gum line, said post defining a threaded recess therein, a screw threadedly receivable within said recess, and locking means for securing said screw within said recess, said screw defining a bore laterally therethrough, said locking means comprising a deformable rod received within said bore and engageable with the threads in said threaded recess.
