1. An implant for filling a bore hole in a bone, comprising:
- a. a single solid ceramic tile body, the tile body having a top surface, a bottom surface, and at least one lateral sidewall extending between the top surface and the bottom surface;
b. a plurality of wire anchoring arms, each anchoring arm having;
i. a first portion embedded in the tile body, the ceramic tile body being moulded around the first portions of the wire anchoring arms to provide an internal wire-supported implant body; and
ii. a second portion extending laterally outwardly from the tile body through a lateral sidewall of the tile body; and
c. at least two anchoring structures, wherein each anchoring structure is connected to the ceramic tile body by the second portion of a wire anchoring arm, and wherein one of the anchoring structures is positioned for securing the respective anchoring arm to a bone flap and another of the anchoring structures is positioned for securing the respective anchoring arm to surrounding bone structure.

Abstract
An implant includes a single moulded implant body and a plurality of wire anchoring arms moulded into and extending substantially laterally from the moulded ceramic implant body for filling a bore hole in a skull. The implant will not only provide filling of the bone defect, but also provide fixation of the bone flap. Methods for forming such implants and methods for using the implants for filing a bore hole in a skull are described.

-
a. a single solid ceramic tile body, the tile body having a top surface, a bottom surface, and one or more lateral sidewalls extending between the top surface and the bottom surface; b. a plurality of radially-extending wire anchoring arms, each anchoring arm having; i. a first portion embedded in the tile body, the ceramic tile body being moulded around the first portions of the wire anchoring arms to provide an internal wire-supported implant body; and ii. a second portion extending laterally outwardly from the tile body through a lateral sidewall of the tile body, wherein the second portions of the respective anchoring arm wires extend laterally outwardly from the tile body at uniformly spaced locations around a perimeter of the tile body; and c. a plurality of anchoring structures, wherein each anchoring structure is connected to the ceramic tile body by the second portion of a wire anchoring arm, wherein the anchoring structures are located at uniformly spaced locations around the tile body perimeter, and wherein the anchoring structures comprise screw-receiving openings. - View Dependent Claims (33, 34, 35, 36, 37, 38)
