Precious metal porcelain-fused-to-metal crowns feature an inner crown composed of over 80% gold alloyed with trace elements like platinum or rhodium. Though higher in cost, they offer distinct advantages: the gold alloy base crown reflects natural tooth luster under sunlight, boasts excellent biocompatibility, ensures safe use, provides superior sealing, and achieves exceptional bonding between porcelain and metal, minimizing porcelain chipping. This type of crown is relatively common.
2. Non-Precious Metal Porcelain-Fused-to-Metal Crowns
Non-precious metal crowns feature a nickel-chromium alloy inner crown overlaid with high-temperature porcelain. This mature restoration technique gained early acceptance among dentists and patients for its effectiveness and affordability. However, it is now increasingly replaced by metal-free and all-ceramic options. This remains a recognized category of porcelain-fused-to-metal restorations.
3. All-Ceramic Crowns
Compared to metal-ceramic crowns, all-ceramic crowns lack a metal inner crown. They offer excellent biocompatibility, realistic color and form, and high aesthetic performance. They are currently the most ideal cosmetic restorations, favored by many patients at Kowa Dental.Kova Dental's all-ceramic crown technologies include: all-ceramic crowns, Swedish all-ceramic crowns, zirconia all-ceramic crowns, and alumina all-ceramic crowns. These represent some of the most effective options within the porcelain-fused-to-metal category.
