    摘要： The present invention relates to a method and a system for preparing dental restorations from ceramic or polymeric material to achieve color and opacity gradients simulating natural dentition, wherein an ingot of ceramic or polymeric material is entirely or partially forced through a system of channels in a press mold into a mold cavity in the press mold, wherein the mold cavity corresponds to a dental restoration.

    摘要： A method for producing an oxide ceramic shaped part includes pressing a powder provided with a binding material or a powder mixture of an oxide ceramic into a shaped part, pre-sintering the shaped part at substantially atmospheric pressure and a temperature of 600 to 1,300° C., and evacuating a closed container in which the pre-sintered shaped part is disposed with the shaped part having a maximum density of 10 to 90%. The container is at an absolute pressure of less than 40 mbar. Subsequently, an infiltration material is applied onto the shaped part via infiltration with the infiltration material operating to seal off the shaped part relative to the surrounding atmosphere. The length of time of the infiltration is preferably 1 to 10 minutes.
