Objective This paper presents a new method of individual prefabricated titanium implant for the reconstruction of the skull bone defect. Method A computer-based 3D model of the cranial bone defect is created from helical CT-data and serves as the basis for the computer aided design and manufacturing(CAD/CAM) of the individual prefabricated titanium implant for the cranial bone defect reconstruction. Result Since 2001,a total of nine patients suffering from the cranial bone defect have been operated on by this method with satisfied result. The fallow-up is 3 to 12 months. Conclusion These individual prefabricated titanium implants have won a high precision,a good biomechanics and a excellent biocompatibility. It is a quite ideal and very simple method with much less complication for the surgical treatment of the cranial bone defect.
