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.
