Abstract

A dental implant assembly (20) including a core body (40, 140, 240, 340, 440) for engaging a tooth-replicating device (52). The core body (40, 140, 240, 340, 440) is disposed in an anchor body (24, 124, 224, 424), and a screw cap body (58) is disposed about the outer attachment surface (30, 130, 230, 430) of the anchor body (24, 124, 224, 424). The screw cap body (58) engages the bone (22) of a person to support the dental implant assembly (20) and holds the core body (40, 140, 240, 340, 440) and the anchor body (24, 124, 224, 424) together.
