Conventional porcelain is fused to non-precious, semi-precious or white high noble gold. It is an ideal restoration for your most demanding patients. We carefully design each coping and framework to provide superb fit, high strength and complete marginal seal.
Indications
Porcelain fused to metal can be used for all single-unit crowns and bridges. Porcelain can be fused to non-precious, semi-precious or white high noble copings. PFMs are also indicated for crowns and bridges used in conjunction with cast partials.
