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.
