Crowns are used to replace missing teeth. They can be made from gold, metal, porcelain and white (Tooth) colored Zirconium. White crowns can greatly improve your confidence and smile.
Ceramic Fused to Metal Crowns Porcelain-fused-to-metal dental crowns are the basic crowns with a metal backing which can be almost color matched to your adjacent teeth (unlike the metallic crowns). However, over a period of time; the ceramic overlaying may wear off or the metal underlying the crown’s porcelain can show through. In the gums it may show through as a dark line. They may be required to be upgraded or replaced after few years.
All Ceramic crowns All-ceramic or all-porcelain dental crowns provide better natural color match than any other crown type and may be more suitable for people with metal allergies. All-ceramic crowns are a good choice for front teeth.
Zirconium is the strongest all-ceramic coping material available today. Zirconium is ideal for those who are sensitive to metal or simply prefer the aesthetics of metal-free restorations. Its bio-compatibility has been proven through the years in the medical field.
Zirconium crowns and bridges are so strong they can be used anywhere in the mouth. Zirconium crowns can withstand the biting pressure of the front teeth as well as back teeth grinding. The look of zirconium crowns and bridges is so close to natural teeth that it is hard to tell the difference and it is this quality which makes it very usable within dental work.
