The modern dental implant is a surgical device, most commonly used to replace one or more missing teeth by fusing to the bone and acting as an artificial tooth root. The term, dental implant, technically refers only to that portion of the structure that is in the bone.

To become functional, however, other parts are attached including an abutment, that comes through the gums, an abutment screw that joins the abutment to the implant and the prosthetic teeth which attach to the abutment.
