摘要：
The invention relates to a navigation system for dental and cranio-maxillofacial surgery, comprising a surgical handpiece (2), an imaging unit (4 ) which is movably attached to the surgical handpiece (2), and a marker member (6； 44, 46) which is attachable to a cranial bone, a facial bone (26), a tooth or teeth of a patient. The marker member (6； 44, 46) comprises a plurality of marker elements (8, 10； 46) which are detectable by the imaging unit (4). Further, the invention relates to a positioning tool (40) for use with the navigation system, wherein the positioning tool (40) is configured for positioning the marker member (44, 46) on a patient's cranial bone, facial bone (26), tooth or teeth and comprises a die element (42) and the marker member (44, 46). The marker member (44, 46) comprises a deformable material (44), the deformable material (44) is releasably received in the die element (42) and the plurality of marker elements (46) are arranged on a surface of the deformable material (44) which faces the die element (42), The invention further relates to a navigation method for dental and craniomaxillofacial surgery using the navigation system and to a method of positioning a marker member (44, 46) on a patient's cranial bone, facial bone (26), tooth or teeth using the positioning tool (40).
