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 or injected into the investment blocks to form the desired dental restoration. Subsequently, after cooling, the dental restoration is divested from the investment mold and finished.
