Full-ceramic crowns are of high-level translucency.
The depth of color and characterization of the natural tooth is possible only with a ceramic crown.
Full-ceramic crowns don’t possess a dark margin.
Metal porcelain crowns composed of a metal substructure fused through the heat with porcelain. At the base of these crowns, there is usually a millimeter of exposed metal to avoid the gum recession and protect the porcelain. However, gum recession over time can expose this metal ring, and sometimes metal stains the gum with dark color. All of that can’t happen with full-ceramic crowns.
Full-ceramic crowns have the same resistance as metal-porcelain crowns.
There is a new type of ceramic that has more resistance than metal and is much more aesthetic. This material is zirconium.
Full-ceramic crowns follow a more conservative prepping.
With metal-porcelain crowns prepping, dentists have to remove more of your natural tooth structure to allow these crowns more space ordered toward excellent translucency.
With the full-ceramic crowns, dentists can remove less of your tooth structure due to their natural-looking color. So, fewer layers of porcelain can achieve the needed transparency.
