Abstract
Abstract A wide vent dental implant adapted to be driven into the jaw bone of an individual and having a wide flat blade portion offering a large surface area for frictional retention in the jaw bone, and a head portion which remains exposed outside the jaw and provides a support for dental appliances of various types requiring an anchorage to the jaw bone. The bottom edge of the blade portion is sharpened to provide a cutting edge which incises the jaw bone as the wide vent is driven into place.

Claim 1
Independent Claim
61 words
A dental implant comprising at least one head portion, and at least one flat, thin blade portion connected to the head portion by a reduced neck portion, said blade portion having a sharpened bottom edge adapted to incise the jaw bone as the implant is driven into the bone by pressure applied to the head portion, said bottom edge being serrated.
Claim 2
Dependent Claim

A dental implant comprising at least one head portion, and at least one flat, thin blade portion connected to the head portion by a reduced neck portion, said blade portion having a sharpened bottom edge adapted to incise the jaw bone as the implant is driven into the bone by pressure applied to the head portion, said bottom edge being serrated.
Claim 3
Dependent Claim
92 words
A dental implant comprising at least one head portion, and at least one flat, thin blade portion connected to the head portion by a reduced neck portion, said blade portion having a sharpened bottom edge adapted to incise the jaw bone as the implant is driven into the bone by pressure applied to the head portion, said blade portion being substantially wider than it is long, said blade portion being symmetrical about a median line and having curved side margins extending outwardly and downwardly from said reduced neck to said bottom edge.
Claim 4
Dependent Claim
92 words
A dental implant comprising at least one head portion, and at least one flat, thin blade portion connected to the head portion by a reduced neck portion, said blade portion having a sharpened bottom edge adapted to incise the jaw bone as the implant is driven into the bone by pressure applied to the head portion, said blade portion being substantially wider than it is long, said blade portion being symmetrical about a median line and having curved side margins extending outwardly and downwardly from said reduced neck to said bottom edge.
Claim 5
Dependent Claim

78 words
A dental implant comprising at least one head portion, and at least one flat, thin blade portion connected to the head portion by a reduced neck portion, said blade portion having a sharpened bottom edge adapted to incise the jaw bone as the implant is driven into the bone by pressure applied to the head portion, said implant having two head portions each connected to a single flat, thin blade portion by a pair of narrow neck portions.
Claim 9
Dependent Claim
37 words
The dental implant set forth in claim 4 wherein said blade portion is substantially wider from side edge to side edge than it is long from the bottom of its neck portion to said sharpened bottom edge.
Claim 10
Dependent Claim
