    Abstract: Disclosed is a dentists' preparation instrument (1) comprising a turbine (4) for driving a tool (3) using compressed air, and a rotor (6) that is arranged in a turbine compartment (5), rotates about a longitudinal axis (7), and has blades (11) extending to a face (13) of the rotor (6). The turbine compartment (5) has a wall (10) opposite the face (13), and a discharge port (12) for the compressed air in the direction of a returning air duct (8). The discharge port (12) is disposed in such a way that at leasts parts of the blades (11) swipe past the discharge port (12) as they rotate about the longitudinal axis (7). The turbine compartment (5) also has a disruptive contour chamber (15) that adjoins the face (13). The face (13) of the blades (11) of the rotor (6) that faces the disruptive contour chamber is open towards the disruptive contour chamber (15). Inside the disruptive contour chamber (15), a disruptive contour (9) is formed on the wall (10) opposite the face (13) by at least one projection (14) extending along a height (h) in the direction of the longitudinal axis (7).

    Abstract: A dental handpiece (1) having a drive (3) of a tool (4), which drive is located in a head housing (2), has at least one media-conducting line arranged in the head housing, which media-conducting line has an outlet opening to the tool, and a tool receptacle (16) arranged in a drive chamber, which tool receptacle is rotatably supported by means of a rolling bearing (11) in a support (14) of the head housing (2) on a side of the drive chamber facing the tool. The rolling bearing has an outer race (13), which is supported against the head housing (2) radially in the support (14) in the area of a raceway (22) and which has a sub-area (21), the outside diameter D2 of which is reduced compared to the outside diameter D1 in the area of the raceway (22). The head housing has a housing projection (23), which extends into the area of the reduced outside diameter D2, and the media-conducting line (17) runs at least partially through said housing projection (23).

    Abstract: A method of identifying dental consumables including at least one of a dental blank (2) and a dental tool (3) equipped into a dental tool machine (1). The method includes: a step of colliding the dental tool (3) with the dental blank (2) or a dental blank holder of the dental tool machine (1) and a step of detecting a signal indicative of the collision. The method also includes a step of analyzing the detected signal through trained artificial intelligence; and a step of identifying the type and/or condition of at least one of the dental consumables based on the analysis.

    Abstract: A method of machining a dental block (2) by using at least one dental tool (4) to finish or pre-finish a dental restoration (5) at least completely along the equator (5a) with or without a holding stub (5b). The method includes: a step of moving the axis (4a) of the dental tool (4) along a path (6) with an overlaid lateral motion having an amplitude (A), and without separating an unmachined piece (2″) from the rest of the dental block (2). The path (6) lies away from the equator (5a) at least by an amount equal to half of the diameter of the dental tool (4) plus half of the amplitude (A) of the overlaid lateral motion.
