Crowns / Bridges

Dental crowns, also known as "caps", preserve the functionality of damaged teeth. Crowns may be used to protect a cracked tooth, restore functionality of a tooth with excessive decay, or replace a pre-existing crown. The purpose of a crown is to encase the tooth with a custom-designed material. We have a variety of conservative treatment options through which to restore teeth. If possible, these options should be explored and discussed on your consultation before selecting the type of crown. 

 

Dental bridges are when one or more teeth are missing. A bridge is simply made up of two crowns one on each side of the tooth, these two supporting teeth are called abutments and the false tooth/teeth in between is known as a pontic tooth.

The Clicincal Procedure

 

During this crown procedure, it will normally take two visits with your dentist. Once in the chair you will need a local anesthetic to numb the area as he preps your tooth as it can become a bit senstitive.  Then he/ she will take a moulded impression of the teeth to send to a dental laboratory. In the meantime  A fitted, temporary crown is created during this visit to temporarily protect the tooth while the final restoration is being made in the dental laboratory. Once completed, the crown is cemented at a later visit approx 10 days later.

 

A recent technology, CAD/CAM technology (computer-aided design/manufacturing technology) has evolved to display a 3-D picture of the teeth. A restoration is then created through milling of a ceramic block. This is also an option available here in the practise. 

 

Crown Materials: Gold, Ceramic and Porcelain Crowns

The three predominant choices of restorative materials for the full coverage crowns are: 

1. Porcelain-fused-to-metal

2. All-ceramic (all-porcelain)

3. Gold

4. zirconia crowns

 

A zirconia crown is a popular type of ceramic crown which is worn to improve the appearance of a tooth, Zirconia is a type of crystal which is long lasting and durable

 

The material selected is determined by the clinical demands at hand; aesthetic demands, strength requirements, material durability and restorative space available. 

 

Porcelain-Fused-to-Metal Crowns

Porcelain-fused-to-metal crowns provide for a strong, durable, and aesthetic treatment option. One of the key factors for the aesthetic and functional success of this type of crown is ensuring the preparation of the underlying tooth structure provides adequate space for the appropriate thickness of the material selected. Additionally, the artistic skill of the laboratory technologist creating the crown will determine its aesthetic appeal. 

 

Gold Crowns

Gold crowns are indicated in some instances for example, patients with strong bites (such as grinding or clenching) might be better served with gold crown. The traditional restorative material can provide stronger support to the remaining healthy tooth structure. Gold crowns offer a level of durability that is appropriate for teeth located in the back of the mouth (such as the molars), where they will not be highly visible. Gold crowns tend to offer greater longevity and require less preparation than porcelain and porcelain-fused-to-metal crowns. When chewing, gold tends to be less abrasive to the opposing tooth than porcelain. This helps to prevent wearing of the teeth.
