Abstract: A registration and identification tool (1) for an instrument (100), comprising a body (2), a marker member (3) which is optically detectable and provided on the body (2), and a recess (4) in the body (2) which extends from an outer surface of the body (2) into the inside of the body (2), thereby defining an extension direction of the recess (4), wherein the recess (4) has a shape such that a lateral extension of the recess (4) decreases in the direction from the outer surface of the body (2) towards the inside of the body (2).

Abstract: The present invention relates to curable compositions comprising a plurality of particles, a primary liquid phase comprising at least one polymerizable or cross-linkable organic compound that can form organic polymers or networks, and a secondary liquid phase.

Abstract: The present disclosure provides compositions, articles, and methods related to altering electromagnetic radiation. An actinic radiation curable precursor composition of a three-dimensional article includes a) a resin comprising an actinic radiation curable component, wherein the resin has a viscosity no greater than 500 cP; b) hollow glass microspheres having a density no greater than 2 g/mL and an average diameter no greater than 200 micrometers; and c) a photoinitiator. At least part of the surface of the hollow glass microspheres comprises a surface coating or modification. An article includes a photo(co)polymerization reaction product of the composition. A method of manufacturing a three-dimensional article includes the steps of a) providing an actinic radiation curable precursor composition; and b) selectively exposing a portion of the composition to a source of actinic radiation to at least partially cure the exposed portion of the composition, thereby forming a cured layer.

Abstract: The invention relates to a 3d-printed dental restoration precursor, a 3d-printed array comprising a 3d-printed dental restoration precursor, a kit of parts comprising at least two 3d-printed dental restoration precursors or 3d-printed dental restorations and a process of producing such a 3d-printed array, 3d-printed dental restoration precursor or 3d-printed dental restorations. The 3d-printed dental restoration precursor comprises at least one crown unit having an outer surface and an inner surface and at least one support element having a fixation section. The support element is connected through the fixation section to the outer surface of the crown unit in a particular region.

Abstract: 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).

Abstract: A Computer Assisted and Robot-Guided Laser Osteotome (CARLO) medical device (1) for perforating hard tissue, having a photoablation laser source (31) mounted in a robotic arm (2), and optical system (37) for focusing a laser beam in a target plane of the ostetomy line featuring an autotracking navigation system (8).
