PCT No. PCT/EP94/00158 Sec. 371 Date Aug. 24, 1995 Sec. 102(e) Date Aug. 24, 1995 PCT Filed Jan. 21, 1994 PCT Pub. No. WO94/16666 PCT Pub. Date Aug. 4, 1994A method is disclosed for the manufacture of a ceramic material for fillings or dental prostheses, which includes the steps of forming a precipitation product having at least one slightly soluble calcium phosphate compound, which has at least two phases of crystals; the slightly soluble calcium phosphate compound being a replacement for dental tissue. The precipitation product further includes a freely soluble compound dissolvable in the saliva of a patient's mouth and which creates a porous structure within the slightly soluble phase. The pores of this structure are filled by precipitating ions from the patient's saliva. The precipitation product is then sintered and dried, before being explosively compressed to form the ceramic dental filing material.
