Claim:
1. A device for forming a cavity in a bone for use with an oscillating dental instrument comprising: a body defining a longitudinal axis; a flange defined on the body having two surfaces that meet an edge, which is oriented oblique to the longitudinal axis; serrations for forming the cavity that are defined on an outer surface of the body at an elevation below the flange, wherein a radial edge of the flange constitutes a top-most serration along the longitudinal axis, and the radial edge of the flange extends around an entire perimeter of the body, and wherein the serrations positioned beneath one surface of the two surfaces of the flange extend non-parallel to the serrations positioned beneath the other surface of the two surfaces of the flange; an internal fluid passageway defined in the body for directing fluid to the serrations on the outer surface of the body; a plurality of side holes defined on the outer surface of the body that are each connected to the internal fluid passageway for delivering fluid to the serrations on the outer surface of the body, wherein one or more side holes of the plurality of side holes are defined at an elevation above the flange and one or more side holes of the plurality of side holes are defined at an elevation below the flange; a concave surface formed on the body that is devoid of serrations, wherein the internal fluid passageway passes through said concave surface; and a connector extending from the flange that is configured to be connected to the oscillating dental instrument, the internal fluid passageway extending up the longitudinal axis and through the connector to define an inlet port at a top end of the connector, wherein fluid introduced through the inlet port is distributed through each side hole of the plurality of side holes.
