Porcelain crowns protect and salvage decayed or fractured teeth.
• Teeth that are extensively affected by decay
• Teeth that have been fractured
• Teeth that need to be protected or strengthened
A crown is also commonly called a cap. A crown covers the tooth and restores it to its original shape and size. Crowns can be made using CEREC systems or in dental laboratories. At AMK Dental Clinic, we offer both systems and are happy to discuss a solution for your particular needs.
Initially, the tooth is treated and areas of decay removed. The remaining healthy portion of the tooth is then assessed for its suitability for a CEREC crown. If considered appropriate, the tooth is then shaped to fit a crown. The tooth is then prepared for scanning. Once scanned, computer software creates a three-dimensional image of the prepared tooth. A crown is designed and created by the CEREC machine to fit precisely over the tooth remnant. The CEREC crown is milled from a block of porcelain and is cemented onto the tooth.
Alternatively a crown can be constructed in a dental laboratory. In this instance, the first step is the same - the decay is removed and the tooth is shaped to fit a crown. Your dentist then makes a highly accurate impression or mould of the prepared surface of the tooth remnant. This mould is used to create a model of the tooth, which is then sent to a dental laboratory. The laboratory technician will create a gold or porcelain tooth-coloured crown. Finally, the crown is then cemented onto the prepared surface of the tooth remnant.
Because they are milled form a solid block of porcelain with a CEREC machine, or crafted in a dental laboratory, crowns are incredibly strong. Crowns will protect and strengthen the structure of the remaining healthy tooth. In the hands of a skilled and experienced dentist, a well-designed crown will fit almost perfectly onto the prepared surface of the tooth. By reducing the size of the seam between the crown and the tooth, oral bacteria are prevented from invading into the tooth remnant. This helps to prevent decay from developing under the crown.
For the best result, a crown should be considered, milled and cemented before tooth decay advances to a stage where the tooth structure is at risk of fracture. A timely crown can help avoid the expense and discomfort of root canal therapy. It can also protect a fractured tooth that may otherwise need to be removed, requiring the necessity of a bridge or implant to replace the missing tooth.
Crowns are excellent restorations and have few disadvantages. Although they are highly durable, they will eventually need to be re-cemented or replaced due to normal wear.
In the event that a tooth is so decayed or fractured that it needs to be removed, the best alternatives to a crown are bridges or implants that replace the missing tooth.
