ABSTRACT:
A method for strengthening and increasing the thickness of the strengthened surface layer of a dental ceramic restorative material where the ceramic material is heat treated with a salt composition containing a lithium ion and a metal ion larger than the lithium ion first at a temperature above the strain temperature followed by a second heat treatment with the salt composition at a temperature below the strain temperature. The treatment is especially effective for all-ceramic, high-leucite feldspathic porcelain restorations.
