A crown is a tooth-shaped cap that improves the strength and appearance of a damaged tooth.
- All-Ceramic Porcelain Crowns are the most realistic looking “caps” for damaged teeth. Your family dentist will likely suggest this option for teeth that show when you smile and when you speak — particularly those teeth in the front of the mouth.
Lithium Disilicate is a modern material that matches the aesthetics of natural teeth very closely.
- Porcelain-fused to metal crowns (PFM) – PFM’s offer many of the benefits of both all-metal and all-ceramic crowns. These crowns provides a stronger bond than regular porcelain crowns because they are connected to a metal structure. These crowns are extremely durable. Recently, pressed-to-metal (PTM) or pressed-over-metal (POM) crowns have been developed using a stronger, more aesthetic type of ceramic, and these are good options for many patients.
BENEFITS OF ALL-CERAMIC OR PORCELAIN CROWNS
- These crowns provide a better natural color match than any other crown type.
- These crowns are more suitable for people with metal allergies.
- All-ceramic porcelain crowns can be used for both front and back teeth.
- There is no grey line at the base of the tooth as there can be with porcelain-fused to metal crowns.
BENEFITS OF PORCELAIN-FUSED TO METAL CROWNS (PMF)
- Porcelain-fused-to-metal crowns are stronger than ceramic crowns, which is especially important on molars.
- PFM or all-metal crowns cost around 10 to 20% less than all-ceramic crowns.
DRAWBACKS OF ALL-CERAMIC CROWNS
- Modern ceramic crowns are much stronger than dental porcelains of the past, but no type of all-ceramic crown can match the durability of all-metal or porcelain-fused-to-metal crowns.
- These crowns usually cost around 10 to 20% more than metal crowns.
- They sometimes chip or break.
- These crowns can wear down opposing teeth, particularly for those patients who grind their teeth.
DRAWBACKS OF PORCELAIN-FUSED TO METAL CROWNS (PMF)
- Gum tissue may pull away from the crown.
- If the tooth’s gum line recedes, the crown’s underlying grey metal edge may show, so these are not ideal for the front teeth.
- A PFM crown may wear on opposing teeth.
- The crown’s porcelain covering may chip.
Dr. Keith Phillips is the first dentist in Washington to earn a Certified Dental Technician credential, specializing in Implants, and he contributed to the highly-acclaimed text “Implant Aesthetics.” He routinely shares his expertise in creating dental crowns with other dentists, prosthodontists and students in the international arena.
Distinctive Dentistry uses cutting-edge training and technology, including lasers, CAD (Computer-Aided Drafting systems) and even 3-D printers. We have an on-site lab with highly skilled technicians who construct crowns to the exact specifications each patient needs.
