Abstract

Objective: To search for a method that fabricates the high strength all ceramic crown by the combination of CAD/CAM and glass-infiltrated alumina.

Methods: Alumina coping was milled by the Cerec II CAD/CAM and glass was infiltrated into alumina by the capillary effect. Vita alpha ceramic was used to veneer the surface of substructure for all ceramic crown.

Results: This technology need not duplicate die and sinter alumina substructure for 10 h, compared with the conventional In-ceram technology. The time of glass infiltration has been decreased from 4 h to 40 minutes by the high capillary effects of prefabricated alumina blocks.

Conclusion: This is a new method for all ceramic crown by using Cerec II CAD/CAM to mill a simple ceramic block so as to fabricate prosthetics in clinic.
