Craniofacial prosthesis

Individual skull reconstructions from titanium are in trauma, tumors, bone diseases, and congenital malformations solutions for the supply of skull defects.

The most common causes of loss to the cranial bone ( calotte ) undoubtedly arise through injury (fracture or fragmentation ) in a fall, or other acts of violence (trauma ). More or less often remain large defects of the bony structures that cause even after healing of the soft tissue covering the scalp to the underlying meninges ( dura mater ), and fuses with it. But a deliberate, surgical removal ( craniectomy ) of parts of the skull bone is necessary, when after a trauma or by bleeding in the brain (stroke ) of this swell and the intracranial pressure rises. Under certain circumstances, parts of the skull bone are then removed by the surgeon, so that the brain can expand. Of particular importance is clinically but also had taken place the implant or to Replantatverlusten after craniectomy.

The optimum bone substitute is anatomically true -made titanium implants have been proven. This secure storage of anatomical brain and protect against further injury. Before the operation is planned on the basis of computed tomography data in virtual reality reconstruction of the defect. Clinically successful and well established is the production of individual titanium implants with large bony defects in the skull. Based on X-ray tomography ( CT, CT ) of a patient, it is possible to construct a tailor-made titanium implant for bone defect by means of computer -aided design (CAD ) in the computer. The data for the preparation of this implant are then transmitted to a computer controlled milling machine. The computer-aided manufacturing (CAM) permits a high precision manufacturing of the implant, which is obtained from a block made ​​of pure titanium.
