List of crown types:
Gold crowns are highly durable and robust and are therefore widely used in the restoration of posterior teeth.
Gold dental crowns are recommended for patients who have a habit of chewing hard foods along with clenching and grinding.
Porcelain crowns are the most commonly used type of crown due to their natural appearance and metal-free construction.
The difference in how they are made results in their naming; the ceramic crown contains a mixture of porcelain and other non-metal material, and the porcelain crown has only dental porcelain.
Porcelain fused to metal/PFM crowns
Porcelain fused to metal crowns is cheaper, and they look like natural teeth, but the metallic composition of the crown's underside may cause gray gum lines. Since porcelain is baked into metal basel, the porcelain will come off or chip.
Zirconia crowns are made of zirconium dioxide, which is more rigid and robust than porcelain and has excellent aesthetics and strength. The zirconia crown can only be carved with CAD/CAM-supported milling machines.
Emax crowns are made from lithium disilicate ceramic, hold similar durability, appearance, and price to zirconia crowns. The E-max crowns are more expensive than the zirconia crowns.
