摘要

A cranial implant designed to fill a cranial defect of the skull of a mammal or a human, wherein the cranial implant is made of biocompatible ceramic and includes an implant body having a shape and size substantially matching the shape and size of the cranial defect to be filled, wherein the implant body includes an outer face facing outside the skull and an inner face facing inside the skull when the implant disposed on the skull, characterized in that the implant includes one or more reinforcing members protruding from the inner face of the implant body. A method of manufacturing the cranial implant is also described.

主权项

1. A cranial implant designed to fill a cranial defect of the cranium of a mammal, said cranial implant being a monolithic structure made of biocompatible ceramic and having a shape and size substantially matching the shape and size of the cranial defect to be filled, the cranial implant comprising:
an implant body having an outer face configured to face outside the cranium, and an inner face configured to face inside the cranium when the implant is disposed on the cranium,
wherein the implant body is porous, the implant body having pores in the surfaces of the implant body, the pores being configured to promote infiltration and colonization of the implant by bone cells; one or more reinforcing members protruding from the inner face of the implant body, the reinforcing members being integrally made with the implant body and configured to protrude from the inner face over a defined thickness, wherein the reinforcing members are non-porous; and a plurality of attachment through-openings positioned at a periphery of the implant body, the through-openings being configured for sutures.
