The cranial implant comprises an implant body (20) having a shape and size corresponding to the shape and size of the cranial defect to be filled, and reinforcing members (31). The cranial implant is made of biocompatible ceramic. The implant body: includes an external face facing outside of the skull, an inner face (22) facing inside of the skull when the implant is placed on the skull, and attachment openings surrounding a non-porous bonding region (24) is porous in the vicinity of a portion of the surface of the implant body and is non-porous in the heart of the implant body.

The reinforcing members: are non-porous protrude on the inner face of the implant body are formed in one piece with the implant body protrude in a thickness that is less than a distance separating the inner face of implant body from an outer face of an underlying anatomical structure such as duramater of the mammal or human receiving the implant when the implant is placed on the head and consist of reinforcement strips and a central element such as a ring or circle. Openings are provided in one of the reinforcing elements, and are provided on an upper face of the reinforcing elements and/or on side faces of the reinforcing elements. The cranial implant has two regions, which have different porosities. The reinforcement strips extend towards the periphery of the implant from the central member, and form a gate. An ind
