Abstract
A process for manufacturing dental prosthetics based on ceramics including the following steps: machine-processing a prefabricated shaped body to form a molded body with the patient's situation being considered, said prefabricated shaped body consisting of at least one oxide-ceramic material selected from the group consisting of aluminum oxide, magnesium oxide, zirconium oxide, and titanium oxide and minor amounts of siliceous additives; compacting the thus obtained molded body; and optionally jacketing the compacted molded body.
Claims14
A process for manufacturing a dental prosthetic comprising the steps of:
- forming a molded-body precursor of the prosthetic by machine-processing a porosity-sintered molded blank by CAD/CAM methods to accurately fit prepared definition according to data on a patient's dental situation, said porosity-sintered molded blank consisting essentially of at least one oxide-ceramic material selected from the group consisting of aluminum oxide, magnesium oxide, zirconium oxide, and titanium oxide and, optionally, a siliceous additive;
- compacting the molded-body precursor by glass infiltration to form the prosthetic.
The method of claim wherein the porosity-sintered molded blank is obtained by a method selected from the group consisting of form-molding and pressing, injection-molding, simultaneous form-molding and pressing, and press-molding a composition comprising a powder of the at least one oxide-ceramic material.
