Abstract: A method for producing a tooth replacement part to be secured on an implant, based on a 3D model of the tooth replacement part with a surface and with a continuous screw channel with an initial shape in the form of a cylindrical barrel, with a first and a second end, wherein a cross sectional area of the screw channel is designed to be constant and/or to increase in size towards the second end of the screw channel. A 3D model of an inlay with a jacket surface, an upper face and a lower face is generated. A part of the surface of the 3D model of the tooth replacement part that is cut out through the second end of the final shape of the screw channel is used as the upper face and the jacket surface is configured as a negative form of a part of the final shape of the screw channel that adjoins the second end.
