Abstract In order to produce oxide ceramic dental prostheses with an accurate fit in a single operation, the mixture of ceramic particles, binders and/or mixing fluids must be prevented from shrinking during sintering. This is done by adding particles of easily oxidizable metals, metal suboxides and/or metal hydrides, which absorb oxygen and increase in volume during sistering and compensate for the shrinkage during sintering, if the mixture is in the right proportions.
