    3D printing cranial and craniofacial implants

    I am a neurosurgeon. The simplest way to solve most of our problems in a low cost and rather according to the rules way is to first to print the patients skull (easy). Than to form manually, slowly and exactly a lacking bone from the cheap, available everywhere in the world dental molds (I have succeeded with silicone prosthetic mold). When the bone substitute is ready and firm, then make an impress in a stomatologic acrylic mass (methacrylate, the ubiquitous surgical material), also available everywhere. Its the same component that we use to form a bone in the operating theatre, but not sterile. If you have the mold ready, you can sterilise it in a plasma autoclave, put in a sterile foil bag in the operating theatre and then form in this foil and form a lacking skull piece from a classic methacrylate. Sterile, with all of the certificates needed. It does work. Ready 3D printed skull flaps are often imperfect. I.e. they do not take into consideration brain swelling, soft tissue remodelling etc. The mold and forming the bone flap during surgery from PMMA seems to be much more versatile. And you do not have to throw away the bone substitute of 2000 USD into trash. Best regards, Piotr
