There are primarily four types of precious metal porcelain-fused-to-metal crowns: palladium-silver alloy, palladium-gold alloy, platinum, and gold.Due to their differing compositions, these four types exhibit distinct properties and advantages. So, what specific types of precious metal porcelain-fused-to-metal crowns exist?
I. Palladium-Silver Alloy Porcelain-Fused-to-Metal Crowns:
High strength, excellent elasticity, corrosion resistance, and no harm to the human body. The strong bonding between porcelain and metal extends their lifespan. They are characterized by being more affordable than gold porcelain-fused-to-metal crowns, offering a higher cost-performance ratio.
II. Palladium-Gold Alloy Porcelain-Fused-to-Metal Crowns:
Excellent porcelain-to-metal bonding, tight marginal adaptation, corrosion resistance, no allergic reactions, and superior ductility and strength. They are more affordable than gold porcelain crowns, offering high cost-effectiveness.
III. Gold Porcelain-Fused-to-Metal Crowns:
Exceptional biocompatibility, preventing discoloration of surrounding tissues.The inner crown's hue closely matches the natural yellowish tone of tooth dentin, resulting in a softer, more lifelike, and natural appearance.
IV. Platinum-Ceramic Crowns:
Exceptional biocompatibility without causing discoloration of surrounding tissues. The inner crown's color closely resembles the natural yellowish hue of tooth dentin, yielding a softer, more lifelike, and natural appearance.
