Pericortical dental implant and inserter therefor

Claim 2

A pericortical clamp to provide anchorage for artificial teeth and adapted for application to the mandible or maxilla, comprising a pair of clamp halves, each half having a relatively planar vertical wall, means interconnecting said clamp halves so that said walls are in adjustably spaced apart clamping relationship on either side of a bone, and post means on one of said clamp halves for mounting an artificial tooth.

Claim 3

A clamp as defined in claim 1, wherein said interconnecting means comprises a pedestal extending inwardly from one clamp half and a pair of straddle arms extending inwardly from the other clamp half and adapted to fit about the sides of the pedestal.

Claim 4

A clamp as defined in claim 2, wherein said post means is mounted on said pedestal.

Claim 5

A clamp as defined in claim 3, wherein said post means comprises a screw secured on said pedestal and a mounting post threadedly received on said screw.

Claim 6

A pericortical clamp as defined in claim 1, and further including a plurality of bone-engaging spikes mounted on the inner face of said vertical walls.

Claim 7

A clamp as defined in claim 2, wherein said pedestal and straddle arms are interconnected in slidably adjustable relationship by a tongue and groove interface.

Claim 8

A clamp as defined in claim 6 and further including adjustable screw means for retaining a predetermined adjusted relationship of said clamp halves.

Claim 9

A dental prosthetic appliance and inserter comprising a pair of relatively movable clamp halves having flat inner faces and adapted to be engaged about either the maxilla or mandible, means on one of said clamp halves for mounting an artificial tooth, an inserter having expandable arms adapted to temporarily retain said clamp halves therebetween during installation on a bone, means on the inserter for expanding and contracting said arms about said clamp halves, mechanical force transmission means for moving one of said clamp halves toward the other to clamp about the bone, and screw means adjustably retaining said clamp halves in position about said bone after removal of said inserter.

Claim 10

A dental prosthetic appliance and inserter comprising a pair of relatively movable clamp halves having flat inner faces and adapted to be engaged about either the maxilla or mandible, means on one of said clamp halves for mounting an artificial tooth, an inserter having expandable arms adapted to temporarily retain said clamp halves therebetween during installation on a bone, means on the inserter for expanding and contracting said arms about said clamp halves, mechanical force transmission means for moving one of said clamp halves toward the other to clamp about the bone, and screw means adjustably retaining said clamp halves in position about said bone after removal of said inserter.

Claim 11

An appliance and inserter as defined in claim 8, and further including means on the inserter engageable with one clamp half to move said one clamp half away from said other clamp half.

Claim 12

An appliance and inserter as defined in claim 8, wherein said expandable arms are stiff spring members normally parallel to each other and said means for expanding and contracting the same comprises a pair of toggle links commonly pivoted at one end to a pusher bar and having their opposite ends pivotally mounted on one of said arms, and power means for advancing said pusher bar to expand said arms for the reception of said clamp halves.

Claim 13

An appliance and inserter as defined in claim 8, wherein said force transmission means comprises a screw jackshaft on said inserter, and nut means engageable with said screw jackshaft and in contact with said one clamp half.

Claim 14

An appliance and inserter as defined in claim 8, and further including screwdriver means on said inserter engageable with said screw means.
