CrownsRaleigh, NCWhen a tooth is weakened by decay or extensive restoration, Crowns, also known as "Caps", encase the remaining tooth structure protecting the tooth from decay & further fracture.
Drs. Barker & Rohner utilize at Tios3 intraoral scanner rather than traditional impression material to capture the preparation of your tooth. This new technology allows for superior accuracy, shade matching, and more expedited turn around for your new crown.
Crowns are made from a variety of materials ranging from all porcelain to gold depending on a patient’s aesthetic and functional desires. Your options include:
- Ceramic Crowns: Ceramic crowns are the most highly aesthetic category of crowns which are available. We use only the best materials in our crowns including: Feldspathic Porcelain, Envision Monolithic Zirconia, and EMAX. New types of Porcelain crowns continue to become available, but we only introduce these into our office once we are scientifically convinced of the quality and longevity of these restorations.
- Porcelain fused to Metal Crowns: are the most widely used type of crowns in dentistry. They consist of a porcelain layer which covers a gold alloy coping. They are highly aesthetic and can handle the heavy loads back teeth produce.
- Full Zirconia Crowns: Full Zirconia crowns are milled using CAD/CAM technology and sintered at 1500 degrees Celcius to produce an almost unbreakable crown. These crowns are excellent for patients who are heavy grinders (bruxism) or have a history of breaking traditional porcelain fused to metal crowns. Full Zirconia Crowns are also a good alternative to gold crowns.
- Gold Crowns: are also available for our patients. For patients who have a history of fracturing porcelain restorations or have extremely heavy parafunctional habits such as grinding or clenching of the teeth, these unbreakable crowns are the longest lasting option.
Diagnosing a Large Cavity
Conditions requiring crown treatment: Badly decayed or broken teeth often must be repaired using a cap or a crown. Dr. Barker or Dr. Rohner will often recommend this procedure when filling the tooth to its proper shape becomes impossible or the remaining tooth structure is too weak to hold a composite filling material without fracture.
Treatment: When preparing a tooth for a crown we will remove approximately 1-2mm of tooth structure on the sides and top of the tooth in order to make room for the crown. The crown will be fabricated and then cemented or bonded into place depending on the material of the crown.
