Abstract
A method of making a dental blank comprises the steps of independently compacting a first and second zone of a quantity of ceramic particles. During compacting, the first and second zones have different compaction factors in at least one stage. Such blanks may be pre-sintered and used in the manufacture of dental restorations. The method may help in controlling the homogeneity of the material structure during manufacturing the blanks.
