The invention includes a support frame for producing a dental workpiece. The frame has a Z axis and comprising wall sections defining a hole that extends along the Z axis through the frame. At least one of the wall sections comprises an adhesive-directing surface extending along the Z axis in a non-parallel relationship. Such a configuration provides optimized methods for affixing a blank to the support frame and optimized properties of the blank after fixation to the support frame.

Device for producing a dental workpiece

A method of making a dental blank comprises the steps of independently compacting a first and second zone of a quantity of ceramic particles. During compacting, the first and second zones have different compaction factors in at least one stage. Such blanks may be pre-sintered and used in the manufacture of dental restorations. The method may help in controlling the homogeneity of the material structure during manufacturing the blanks.

Frame containing ceramic block for producing dental crowns and bridges

The present invention is related to systems and methods for manufacturing dental prostheses, such as bridges and crowns. In particular, the present invention is directed to novel methods for managing machining jobs for manufacturing dental prostheses in a system having a plurality of machining devices.

System and method for manufacturing dental prostheses

The invention relates to a method for producing dentures by milling a workpiece. The inventive method is characterized in that in the event of a change in the load on the workpiece or on the milling tool, or on the workpiece and on the milling tool, determined before the milling begins and occurring during the milling, the relative speed between the milling tool and the workplace is varied without using a regulation technique.
