Made with cobalt-based metal-ceramic alloy, our non-precious alloys provide a cost effective solution for prosthetic applications. With regard to the crown’s metal base, a crown of this nature is designated as such because less than 25% of its composition is of the noble metals gold, platinum, palladium, and silver, and its predominant makeup is of chromium. This metal strengthening core is covered with porcelain that is fused to the metal, achieving excellent cosmetic results and durability.
