Abstract
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.
Claims12
A cranial implant designed to fill a cranial defect of the skull of a mammal or a human, wherein said cranial implant is made of biocompatible ceramic and comprises 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 comprises an outer face facing outside the skull and an inner face facing inside the skull when the implant is disposed on the skull, characterized in that the cranial implant comprises one or more reinforcing members protruding from the inner face of the implant body.
A method for manufacturing a biocompatible ceramic cranial implant, characterized in that it comprises the following steps:
- acquiring a three dimensional image of the skull of a patient having a cranial defect;
- building, by computer-aided design, an implant body computer model whose shape substantially matches the cranial defect and whose size is slightly larger than the cranial defect, so as to anticipate shrinking of the ceramic during manufacturing of the cranial implant;
- adding reinforcing members, by computer-aided design, to this implant body computer model, so as to obtain a cranial implant computer model, wherein the reinforcing members protrude from the inner face of the implant body;
- manufacturing a biocompatible ceramic cranial implant by rapid prototyping using the cranial implant computer model.
