Implants for filling a bore hole in a bone, for example, a skull, comprise a single ceramic implant body, of width D and thickness H, and a plurality of substantially laterally extending anchoring arms. The implants provide both filling of the bone defect and fixation of the bone flap. Methods for forming such implants employ moulding techniques. Methods for using such implants for filling a bore hole between a bone flap and surrounding bone comprise fixing one or more anchoring arms to the bone flap and one or more anchoring arms to the surrounding bone.
