Abstract in another language

One of the steps during the implementation of hearing aids and cochlea implantats is the creation of a shallow implant bed in the skull bone. Correct placement of the implant is paramount but difficult to achieve preoperatively. The profile of the calotte, which can be determined through e.g. 3D imaging, is important for this task. Additionally in a robot based surgical operation, the final position and orientation of the implant must be known before milling starts to ensure optimal fitting. We present an algorithm which allows semi-automatic determination of this optimal placement through both the planning system and the surgeon. The computer supports the surgeons with his speed and accuracy, while the robot aids in the precise execution.
