    摘要： A method for producing a dental restoration wherein a tooth preparation area is scanned either directly or indirectly. The scanned data is used by a computer controlled milling machine to create two or more investment blocks (50, 52, 54) for preparing a suitable dental restoration, the investment blocks being of a material which may be used in ovens operating in a 800 to 1,200°C range. A suitable dental restorative material (18) and the blocks are place in an oven, and after being clamped together, the material (18) is pressed into the investment blocks to form the desired dental restoration. Subsequently, after cooling, the dental restoration is divested from the investment mold and finished.
