Abstract

Production of a dental prosthesis to fit prepared tooth stump(s) with a full-ceramic base of biocompatible material comprises scanning a positive model of the base; digitalizing and linear enlargement of the data in all directions to compensate exactly for shrinkage on sintering; using the data to control machining; direct dense sintering; and facing with porcelain or plastics coating material to suit the individual. Production of a dental prosthesis to fit prepared tooth stump(s), allowing for shrinkage, with a full-ceramic base of biocompatible material, involves machining a blank, dense sintering and coating. The process comprises (i) scanning the 3-dimensional outer and inner surfaces of a positive model of the base for crowns and/or bridges and digitalizing the data; (ii) linear enlargement of the data in all spatial directions to compensate exactly for shrinkage on sintering; (iii) transferring the data to the control electronics of machine(s) and tools for machining the blank from porous ceramics, with occasional decoupling from digitalization; (iv) direct dense sintering; and (v) facing with porcelain or plastics coating material to suit the individual. An Independent claim is also included for porous ceramic blanks for use in the process. Information codes in (machine) readable form, giving data for the individual compensating enlargement factors, are provided on the porous ceramic blanks or their packaging, tags or notes in the package. The identification codes especially are suitable for optical, electromagnetic or mechanical-tactile reading.
