| 摘要 | PURPOSE: To form one or more layer to a dupulicated tooth produced under the control of a CAD-CAM system to optimally adapt the color of the dupulicated tooth to the color of an existing tooth. CONSTITUTION: A duplicated tooth coinciding with the three-dimensional drawn image 1 of a treated tooth is cut from a refractory material under the control of a CAD-CAM system by a three-dimensionally driven numerical value control cutter. Next, a metal layer 2 composed of a known metal alloy suitable for baking ceramic is formed to the upper part thereof. This ceramic layer 3 conceals the metal layer 2 for the optimum coloring adaptability. Further, a dentine ceramic layer determining the color of a tooth crown finally is formed. | ||||||
