Are CEREC® Dental Crowns Made With Different Materials?
A person could become concerned when the term “crown” is used by a dentist, and it can be confusing trying to understand the difference between traditional crowns and CEREC® crowns. Abscessed or broken teeth are reasons a dentist may suggest such a treatment. Traditional crowns can be very expensive and require multiple visits, making it more difficult to schedule, making the CEREC® more desirable.
Why are crowns needed?
Crowns are a sound covering for a badly damaged. When a filling or veneer is not an option, the tooth needs to be capped to preserve it. The following are some of the reasons caps may be necessary:
- To add stability to a tooth which has been cracked or broken
- To cover a tooth which has had a root canal
- To cover the hardware of implants
- As a cover for teeth that abut a bridge
- As a protective cover over a large filling, preventing breakage
What materials make up crowns?
For a patient to make a good decision, it is important to understand the different types of crowns and the materials used to make them. It may also help to know some of the advantages or disadvantages.
Following the exam on the first visit, the natural tooth will be filled or a root canal performed and a filling or temporary cap applied to the surface. Impressions will be taken and a permanent crown will be manufactured offsite. On the second visit, the temporary crown will be removed. The tooth will be prepped, and the permanent crown will be seated, cemented in place and adjustments will be made.
The materials typically used for such a crown include all-porcelain, a porcelain surface fused to a metal base or all metal, which is a good choice for back molars. People with allergies to metal should avoid the use of such a cap. Resin can also be used, and while it is easier to match surrounding tooth color, it is also more easily pitted, chipped or scratched.
The process for these crowns begins in much the same way — an exam is done, and a filling or root canal is performed. This is where the similarity ends, however. This type of cap is made entirely of non-allergenic and durable ceramic. It is a strong material that reflects light in much the same ways as natural teeth and can be color-matched to the surrounding teeth. Unlike metal crowns, it is unaffected by temperature, so it will not contract or expand. It is also biocompatible, allowing the gum tissue to grow up around the base.
The dentist can craft them right in the office during the appointment. X-rays and photographs are captured and then converted to 3D imaging. A block of solid ceramic is placed in a special machine and shaped to an exact match for the tooth. The crown is then cemented into place, eliminating the need for subsequent visits.
Taking into account the time saved, the strength of the ceramic material used and the accuracy of the 3D imaging, a CEREC® crown is definitely worth considering. When a natural appearance is desired and a patient wants to be finished in a single day, this is a great choice.
