Dental Crown

Dental Crown

Crowns are dental restorations that are placed over a tooth when other procedures like Bonding or Veneers are simply not enough to restore the damaged tooth. Dental crowns are a popular form of treatment for patients with damaged, broken or worn-down teeth that restore a tooth’s shape and strength, improving the cosmetic appearance of a tooth. Additionally, crowns can protect teeth that have been filled by root-canal treatment. Crowns are permanently cemented to your existing teeth thus requiring the same level of care and attention as your natural teeth. Dental crowns can be aesthetically fabricated to reflect “light” like natural teeth, and mimics the shape, size and colour of the surrounding teeth.

Dental crowns can be made from metal, such as gold, ceramic materials such as porcelain, or a combination of both, known as Porcelain-fused-to metal or ZIRCONIA. Metal dental crowns are usually placed on those teeth that are not overly visible when a person smiles. Dental crowns fabricated from all porcelain possess a translucency that makes them the most cosmetically pleasing of all of the different types of dental crowns. Although they can be very natural in appearance, they lack strength making them the material of choice for front teeth, due to chewing and biting forces exerted on these teeth. Porcelain-fused-to-metal dental crowns can be a good choice for either front or back teeth as they are a hybrid of porcelain and metal.

 


Therefore, they will provide an aesthetically looking crown with sufficient support to withstand the natural biting forces, but they are not aesthetically as good as ZIRCONIA. Moreover there are chances of porcelain chipping and wearing out over a period of time when metal starts showing up. Therefore, ZIRCONIA crown is preferable crown instead of porcelain fused to metal. Metal in the crowns irritates the gum margin and over a period of time the gum recedes and the metal margin appeared on gum line.

Types of Crowns

Crowns can be made from all metal, porcelain-fused-to-metal, all resin, all ceramic or Zirconia.

All-ceramic or all-porcelain dental crowns provide the best natural colour match than any other crown type and may be more suitable for people with metal allergies. However, they are not as strong as porcelain-fused-to-metal crowns or Zirconia crowns and they wear down opposing teeth a little more than metal or resin crowns. All-ceramic crowns are a good choice for front teeth.

Zirconia crowns and bridges are very strong and can be used anywhere in the mouth. They can withstand the biting pressure of the front teeth as well as back teeth grinding. These crowns have quickly become the preferred material for dental crowns. Zirconium is a very strong substance that can endure wear and tear of everyday use. When looking at Zirconium crowns from an aesthetic point it is clear and very similar to a natural tooth and reflects light the same way. This may be important if your new crowns are on the front of your mouth and it is particularly relevant in cases where the crown will be seen next to the natural teeth. The Zirconia crowns are fabricated by the world’s best known companies labs in India and come with a 5 to 15 years warranty for any breakages and replacement is free. This itself shows that how strong and durable is the Zirconia material. These are fabricated by CAD (Computer Assisted Designed) & CAM (Computer Assisted Milling) Procedure by a 3D technology.
