The present invention relates to a ceramic white body of the pre-sintered A dental milling tools for machining with multi-axis CNC milling machine, and is curved hemispherically, the maximum outer diameter of about 1~4mm (Dk) and a spherical end portion switched to the shaft-like milling unit (2) (1), the said shaft-shaped milling part (2) is constant in the outer diameter (Dk), and extends in the axial direction, the shaft-shaped milling part ( 2) is joined to the shaft portion (3), the shaft portion (3) is associated with a dental milling tools extending axially greater than or at least as large as the shaft diameter (Ds). Three, and preferably two grooves for cutting scrap (4), a corresponding number of cutting teeth (5) extends helically around the groove bottom (9), the groove bottom portion (9) of solid consists material and has a circular cross-section the spherical end (1) along the shaft-like milling unit (2). View in the axial direction and extends in a bow shape in the spherical end (1), cutting edge extending over the radial coordinate of the maximum outside diameter in the shaft-like milling unit (2) (Dk) (6) is in the right direction of rotation provided at the outer end of each of the cutting teeth (5) facing the said groove (4). The present invention, the cutting teeth and the groove (4) (5) is characterized in that extending spirally in the left helix. The present invention further is related to the milling process for the manufacture of dentures, the method denture white body to be in the finished denture by sintering, pre-sintered ceramic white bodies, in particular zirconium oxide white body from, in multi-axis CNC milling machine, using a dental milling tool according to any one of claims 1 to 9, the three-dimensional free-form milling along a moving path is generated, it is machined It characterized the Rukoto. .BACKGROUND本発明は、多軸CNCミリング加工機で予備焼結済のセラミックホワイトボディを機械加工するための歯科用ミリングツールであって、半球状に湾曲し、約1~4mmの最大外径(Dk)において軸状ミリング部(2)へと切り替わる球状端部(1)を備え、当該軸状ミリング
