Abstract: A method forms a non-circular socket in a jawbone of a patient for receiving a dental implant. A pilot hole is formed in the jawbone. A framework having one or more sets of opposing drill points configured to rotate along axes that are transverse to a vertical axis is directed along the pilot hole. The framework produces the non-circular socket, which may have a series of tiers. A dental implant is inserted into the socket. The dental implant may have a series of tiered sections shaped so that each tiered section conforms to a respective one of the tiers in the socket. An abutment may be securely fastened to the dental implant.

Abstract: A dental implant has a plurality of tiers each having a non-circular outline. Each tier has maximum dimensions of its respective outline along two transverse axes. The maximum dimensions of a given tier are smaller than the maximum dimensions of an adjacent tier. Accordingly, the tiers taper generally from a larger outline to a smaller outline in a vertical direction from a top well to an opposing bottom of the implant. An abutment may be received on the implant.

Abstract: A drill forms a dental implant fixture socket having an ovular cross section with a series of tapering tiers that are widest near the gumline and narrowest near the root. The drill may have laterally oriented opposed drill points each having an ovoid or conical shape. Mechanical transmission elements operatively connect the gears to a dental hand piece. A plurality of differently sized drill point pairs can be provided along the length of a framework to allow a multi-tiered socket to be formed in a single drilling pass. An implant fixture may have a generally ovular or non-circular cross section having a plurality of tiers that successively narrow in a direction from the gumline region toward root region. The tiers are adapted to fit snugly with the resulting socket tiers formed by the drill. The fixture can be adapted to receive abutments.
