摘要：
The invention relates to a positioning device (1) for cranial bone portions, for relative positioning of the cranial bone portions relative to each other and for obtaining a predefined overall shape and overall contour in order to achieve a target cranial shape, having a primary body (2) designed to bear the cranial bone portions, wherein the primary body (2) is produced based on individual patient data, which are specific for the patient to be treated, and supplemented by modified, anatomical data. The invention furthermore relates to a production method for producing such a positioning device (1), which is prepared to have cranial bone portions temporarily fastened to it, wherein in one manufacturing step, a primary body (2) of the positioning device (1) is produced, based on geometric data representative of the cranial bone geometry of the particular patient to be treated. The invention also relates to a system comprising a positioning device (1) according to the invention and a cranial-bone fastening device (16) for temporary fastening of a cranial bone portion to the primary body (2) of the positioning device (1) in order to orientate the cranial bone portions relative to each other, wherein a pin-shaped fixing element portion (17) is provided on the cranial-bone fastening device (16), which is designed to contact the cranial bone portion or several cranial bone portions on one side while interacting with a counter portion (18) arranged on the other side of the cranial bone portion or cranial bone portions to fasten it or them on the primary body (2) of the positioning device (1).
