Just as there are different situations in which your dentist may recommend a crown, there are also different types that may be recommended based on your unique needs. The option for “same day”, or “CEREC” crowns, is a relatively recent advancement in dental technology.
Same day crowns allow the patient a choice to complete the treatment preparation and placement in a single visit to the clinic as opposed to the traditional process which involves two trips to the clinic with the application of a temporary crown and a waiting period in between.
Why get a dental crown?
It is a protective cap that covers a weakened or compromised tooth. Your dentist may recommend one for one or more of the following reasons:
- To support a root canal tooth which has a tendency to become brittle over time
- To repair a cracked or broken tooth
- To support a weak tooth due to a large filling or cavity
- To complete a dental implant
- For a dental bridge procedure
Using computer software which takes a 3D image of the tooth and transfers it to a milling machine, these can be milled on-site in the clinic.
Since these are made of a solid block of ceramic, they are considered to have a very strong structure.
These are not only known for being strong, but ceramic provides a very natural looking product which reflects light in a similar way to our natural tooth structure. Additionally, the ceramic blocks come in a wide variety of shades and colours, so it can be selected to blend in naturally with your surrounding teeth.
CEREC technology is impressive, but is not necessarily right for all patients. Depending on the circumstances and location of the tooth to be restored, other types of crowns may be more appropriate. Also, it may not be the best option if you require multiple restorations. The milling machine has a limited capacity and therefore this option not recommended for more than two restorations in a single visit.
Different situations may require different types of crowns. Your dentist can help guide you according to your situation and help you determine which type is best for you.
These are a long-standing and proven treatment option with a process that includes having them constructed in a dental lab. The patient, therefore, must make two visits to the dentist to complete this procedure. The first visit is to prep and take an impression of the tooth and the second, usually about 2 weeks later, is to place the crown. In the interim two weeks, the patient is fitted with a temporary crown.
Other types of crowns
These are made entirely of porcelain and with advancements in technology, they too are extremely strong. Very natural shades are easily achievable because of the transparency of the material. Patients are often sent for custom shading at the dental lab.
Porcelain fused to metal (PFM)
In this option, a metal crown is covered with porcelain for a natural look. This option can be used in all areas of the mouth.
These are usually made from a mix of gold and metal alloys. They are extremely strong. This option does not look natural however, so are normally used for teeth in the posterior of the mouth.
