Crowns and bridges can be created out of metal or ceramic or a combination of both, each has its own advantages.
E.Max: Superior durability, esthetics and ease of use
This ceramic material is truly a revolution for the dental industry, combining superior durability, esthetics and ease of use in one product. When fabricated to full-contour, the monolithic structure is the most robust ceramic system tested to date. The opalescence, translucency and light diffusion properties of e.max were all designed to replicate natural tooth structure for beauty and undetectable restorations.
Zirconia: Virtually chip-proof
Zirconia ceramic is a monolithic solid zirconia restoration that is typically six times stronger than e.max. Zirconia ceramic is virtually chip-proof. These restorations exhibit improved translucency and color similar to natural dentition, making them a restorative option in the anterior as well. Complete color penetration all the way through the restorations ensures greater shade consistency and prevents any shade changes after occlusal adjustment.
Metal: For patients looking for strength and durability
All-metal crowns, such as those made out of gold alloy, provide a classic option for patients looking for strength and durability above all else. They can be expected to withstand even the heaviest of biting and chewing and will not chip. They also have a wear rate similar to tooth enamel, so they won’t create excessive wear on surrounding teeth.
PFM: Suitable for front teeth restorations
Porcelain fused to metal (PFM) restorations are an affordable and reliable choice. The metal provides strong compression and tensile strength, while the porcelain gives the crown a white tooth-like appearance, suitable for front teeth restorations. A variety of metal alloys containing precious metals and base metals can be used, and the porcelain can be color-matched to the adjacent teeth.
