Abstract: The invention relates to a method and to a corresponding system for providing a dental prosthesis made from ceramic material having a colour matched to the patient comprising the following steps: (i) receiving a desired nominal colour for the dental prosthesis, determining a deviation between the nominal colour and actual colour of the sintered ceramic material by the control unit and defining a temperature time cycle having a cycle time suitable for compensation of the deviation, for sintering at a defined sintering temperature and creating a corresponding sintering program by the control unit; and (ii) adjusting the actual colour of the selected ceramic material to the nominal colour in the sintering furnace by the sintering program executed by the sintering furnace.

Abstract: A motor-driven dental device has a motor control that is responsive to a load placed upon the motor. More specifically, the invention relates to a dental device having motor that drives a tool, wherein the tool is activated or otherwise controlled in response to a load placed upon the motor through the tool, such as by touching the tool to a surface. The tool may also be controlled by the sustenance, over a predetermined time period, of an increase or decrease in motor current beyond a predetermined hysteresis current threshold. The motor may be an electric motor, a rotary electric motor, and air driven motor, an ultrasonic device or the like.
