How Long Can I Expect CEREC® Crowns to Last?
CEREC® crowns have made it possible to have teeth covered with crowns during a single visit. That means less time taken away from work, school, or other activities to get the dental treatments that you need. These are durable restorations that can last up to 30 years when maintained with good oral hygiene.
Dental crowns are multi-purpose restorations that have restorative and cosmetic uses. They protect the teeth from bite forces and from falling apart due to decay or trauma. Crowns also protect teeth from acids in the mouth that can eat away at their structures. Crowns can even be used as cosmetic tools to cover up discolored or deformed teeth.
The conventional way of getting a crown involves at least two trips to a dentist. The initial appointment is used to prepare the patient’s tooth for the restoration and make an impression of it. This impression is sent to techs at a dental lab that makes restorations. The crown is made there and sent back to the dentist so the patient can be fitted with it during a second appointment.
How CEREC crowns work
Chairside Economical Restoration of Esthetic Ceramics (CEREC) gives dentists the ability to make dental crowns on-site. Also known as same-day crowns, these make getting a crown more convenient, and the patient can get a ceramic crown that is durable and looks natural. CEREC crowns are made from solid ceramic blocks, so patients who are interested in metal or metal-fused-to-porcelain crowns still have to do the conventional method.
Getting a CEREC crown starts with a dental consultation. The dentist will examine the patient’s mouth to determine if CEREC is the right solution for their dental problem. In many cases, issues that can be fixed with a crown can also be fixed with other treatments, like the application of composite resins, so the dentist must verify that a crown is the ideal solution for the patient.
A shot of a local anesthetic is administered before the dentist starts preparing the patient’s tooth. This prevents the patient from feeling pain as the dentist chips away at the enamel on all four sides of the tooth. This is done so the crown fits better with the tooth being repaired. CEREC crowns are made to a higher level of precision than traditional crowns, so less enamel needs to be removed in preparation for the crown. However, the process is still permanent, so the tooth will always need a restoration to protect it moving forward.
A 3D model of the patient’s tooth is made using digital images, and the data is transferred to a screen connected to the CEREC machine. The dentist uses the interface to design the patient’s restoration. Once the patient and their dentist are both satisfied with how the digital crown looks, a ceramic block that has been color-matched with the patient’s tooth is inserted into the CEREC machine that mills crowns. The patient’s restoration should be ready in about 20 minutes. The crown is then fitted to the patient’s tooth to complete the treatment.
