초록 ▼

There is disclosed a method of manufacturing artificial tooth restorations for natural teeth or implants comprising a ceramic densely sintered, high-strength individual core B with dental porcelain A by powder metallurgical manufacturing methods. The inner surface I of the core B, which will fit against one or more prepared tooth surfaces P or artificial abutments, is manufactured by forming a ceramic powder mixture against a surface of a body at which this mentioned surface is manufactured by registering the surfaces of the prepared teeth or artificial abutments and their mutual relationship with a three-dimensional optical or mechanical reading method directly in the mouth or on a model of, e.g., plaster, after which the registered surfaces are reproduced in an enlarged size, e.g., with a computer-controlled milling machine. The amount of enlargement is calculated from the shrinkage of the ceramic material during sintering to full density and considering the gap for cement.

A method for making artificial tooth restorations comprising a ceramic and comprising a densely sintered, high-strength core and dental porcelain atop the core comprising: (a) registering the surfaces of a tooth to be restored or artificial abutments and their mutual relationship with a three-dimensional optical or mechanical reading method directly in the mouth or a model thereof; (b) reproducing the registered surfaces in a body by a computer-controlled milling machine at a size enlarged to compensate for shrinkage of the ceramic material to be used for the artificial tooth restoration during sintering and for any gap required for cement; (c) forming a ceramic powder mixture against the reproduced surfaces to form artificial tooth restoration precursors having inner surfaces which will fit against the said surfaces of a tooth to be restored or artificial abutments; (d) sintering the said artificial tooth restorations; and (e) applying a dental porcelain to the outer surface of the core.
