A method of brazing a sintered zirconia ceramic body, comprises: providing a sintered zirconia ceramic body having a surface; chemically reducing the sintered zirconia ceramic body in whole or in part to form a reduced surface to the sintered zirconia ceramic body; applying a brazing material to at least part of the reduced surface to form an assembly comprising said brazing material and sintered zirconia ceramic body; heating said assembly to a temperature sufficient to at least partially melt the brazing material such that the brazing material wets the reduced surface; and cooling the assembly to solidify the brazing material.

A method for making ceramic fixed partial dentures comprising separating the as-sintered partial denture structure, rejoining the retainers and pontic with glass, which forms a strong joint between the retainers and pontic after sintering. This method may produce ceramic long-span fixed partial dentures with a better fit.
