1. A craniofacial implant selected from the group consisting of an infraorbital rim implant, a mandible chin implant, and a paranasal implant configured to be implanted onto a boney structure beneath soft tissue, the implant comprising:
- an inner contoured surface conforming to the boney structure when the implant is implanted onto the boney structure beneath soft tissue;
an outer contoured surface underlying the soft tissue when the implant is implanted onto the boney structure beneath the soft tissue;
an edge disposed about a periphery of the implant at an intersection between the inner contoured surface and the outer contoured surface; and
at least one registration flange extending from at least a portion of the edge disposed about the periphery of the implant, wherein the registration flange is located completely along the portion of the edge, the registration flange positioned so as to abut a landmark feature of the boney structure selected from the group consisting of a lateral aspect of an orbital floor, an inferior border of a mandible body, a posterior border of a mandible ramus, and a pyriform aperture when the implant is implanted onto the boney structure beneath soft tissue such that abutment between the registration flange and the landmark feature allows accurate positioning of the implant relative to the landmark feature,wherein the implant defines a straight line extending from and tangent to the implant only at the edge at a first location and at the edge at a second location, the straight line intersecting with the registration flange at the first location and the registration flange extending along a direction of elongation that is substantially perpendicular to the straight line.
