1. A modular dental implant kit, comprising:
- a head configured for supporting a dental prosthesis, the head defining a generally cylindrical apical end, the apical end having an exterior threaded portion configured for engaging bone;
an intermediate part configured for engaging bone and including a porous sleeve defining axially opposed ends and having passages through the sleeve configured for receiving bone ingrowth;
an anchor configured to engage the head so that at least the head and the anchor cooperatively secure the intermediate part to form a modular implant, the anchor defining a generally cylindrical coronal end, the coronal end having an exterior threaded portion configured for engaging bone; and
a core configured to extend axially through an interior of the porous sleeve and configured to fasten the head and anchor together such that the head and anchor abut respective opposed ends of the porous sleeve to axially encase the sleeve about the core, wherein at least one of the sleeve and the exterior threaded portions of the head and the anchor are configured to promote osseointegration of the modular implant.

Abstract
A modular implant includes a head, an intermediate part configured to engage bone, and an initially separate anchor configured to engage the head so that at least the head and the anchor cooperatively secure the intermediate part on the implant to form the modular implant. At least one of the head, the intermediate part, and the anchor has a plurality of forms, and each form is configured to be assembled on at least one form of the other two of the head, intermediate part, and anchor. The intermediate part may include a porous metal such as tantalum.
