Tailor-made cranioplasty using CAD-CAM technologies

Treatment of traumatic head injuries and various neurosurgical conditions sometimes includes a removal of a large part of the cranial bone. Later on, the formed crane window must be closed with an implant. In this paper we present a method that allows producing implants of any size and complexity, with accurate fit and relatively low manufacturing cost. The implants are finalized upon virtual verification and need short operations to built in the cranial bone. The method can be used also for changing existing implants.
