In one embodiment, a system for making a dental restoration is provided. The system includes a machine unit for processing a dental material to form the dental restoration, and a control unit for controlling the operation of the machine unit. An air channel for discharging a process-originated material from the machine unit provides an air connection between the machine unit and the control unit. Certain embodiments of invention are advantageous in that they help to increase the reliability of the machining operation.

System for making a dental restoration providing ventilation of a control unit of the system, and a corresponding method

Milling machine

In a device for the automatic production of dental replacement parts, a blank is fitted in a substantially plate-shaped carrier body which is so dimensioned that the blank does not exceed the carrier body in any direction. The carrier body serves not only for holding the blank in the working machine but also for protecting it during its automatic handling in magazines or the like. The carrier body is provided with a bar code which relates to the material and dimensions of the blank and may identify data according to which the blank is to be worked The bar code is adapted to be changed by the working machine so as to prevent the carrier body from being reused with the same or a different blank
