There are many different types of dental crowns, including metal-based crowns and metal-free crowns. It is helpful to have a complete understanding of the benefits of each type and when one might be better than the other when deciding which is best for you.
An overview of metal-free crowns
Metal-free crowns are a great way to restore the size, shape and function of a natural tooth that is damaged or severely weakened. The following is everything to know about metal-free crowns, including what they are exactly, how they compare to other types of dental crowns and when they are the best form of treatment.
What are metal-free crowns?
Metal-free crowns are exactly that –– dental crowns that do not contain any metal. They are typically comprised of a ceramic material that is porcelain-based. There are many advantages to choosing metal-free crowns.
Many dentists and patients prefer them to base metal crowns since they are closer to the shade of the natural tooth, which often makes them ideal for more visible teeth. The new variations of ceramic materials being used for crowns are very strong.
Different types of dental crowns
There are essentially four different types of crowns, which include metal-free, metal alloy, gold and porcelain-fused-to-metal crowns. Each type has unique advantages and there are certain times when one may be a better option than another.
Most dentists practicing modern dentistry recommend using metal-free crowns for front teeth as they are the most aesthetically pleasing, and also for molars and premolars, as the new porcelain based metal free crowns made of zirconia are very strong.
These metal free crowns are strong, natural looking and durable.
Metal-free crowns for back teeth
In most cases, ceramic based Zirconia crowns will be appropriate for premolars or even molars, as they have proven to be strong and esthetic.
Another option for patients to consider is porcelain-fused-to-metal crowns, which is connected to a metal structure and durable, yet still adds some aesthetic value of a ceramic crown. However metal free crowns are replacing the porcelain fused to metal crowns in modern dentistry.
How to choose the best type of crown
The best way to determine which option is best for you is to discuss your treatment options with a dentist. He or she can further explain the advantages and disadvantages of each option. He or she can also conduct an oral examination and make a treatment recommendation based on your specific needs.
