摘要

The blank (1) for the manufacture of preferably provisional crown bridges or similar, comprises a blank block (2) and a holder (3) for the clamping of the block in a finishing machine. The block and the holder are constructed in one piece and consist of the same material. The material for the blank may be a synthetic material, ceramic, or a mineral material. An independent claim is included for a method for the manufacture of preferably provisional crown bridges in which a one-piece blank consisting of a block and holder are manufactured in a cutting machining process.
