CEREC Teeth Filling Restoration
WHAT IS CEREC?
CEREC (Chairside Economical Restoration of Esthetic Ceramics, or CEramic REConstruction) is a ceramic dental filling product that allows a dental practitioner to produce the most durable indirect dental restoration using a variety of assisted technologies, including 3D photography and CAD/CAM .
With CEREC, teeth can be restored with ceramic (porcelain) in a single sitting with the patient, rather than the multiple sittings required with earlier techniques. Additionally, with the latest software and hardware updates, crowns, veneers, onlays and inlays can be prepared, using different types of ceramic filling materials.
WHAT ARE THE BENEFITS OF CEREC?
The ceramic material has a proven track record with a high durability rate from 95-99%. No restoration is better than natural teeth, although the Cerec material comes very close. The Cerec ceramic best simulates tooth structure with a similar strength, feel and colour. The high durability rate of the Cerec ceramic is only bettered by cast gold, however, cast gold is not tooth coloured and therefore, using it will not create the natural appearance of the Cerec.
High strength, flexibility and aesthetic has made Cerec by far the best option to replace old silver Amalgam restoration.
HOW IS CEREC APPLIED?
The treating dentist prepares the tooth being restored either as a crown, inlay, onlay or veneer normally under local anaesthesia. The tooth is then powder sprayed with a thin layer of blue anti-reflective contrast medium, imaged by a 3D imaging camera and uploaded to the CEREC computer.
Using the proprietary CEREC software in various modes, a restoration can be designed to restore the tooth to its appropriate form and function. This data on this restoration is stored in a file and is sent via wireless serial transmission or direct wiring to a milling machine.The restoration can then be milled out of a solid ceramic or composite block. Milling time varies from as little as four minutes to as long as twenty depending on the complexity of the restoration and the version of the milling unit.
Should I have my Amalgam fillings replaced?
Dentists replace amalgam fillings for a variety of reasons including recurring decay under Amalgam, fracture of amalgam restoration , endodontic treatment and ugly appearance of Amalgam showing in smile line.
If you seek replacement of quite satisfactory amalgam fillings for other reasons, such as a concern about the effects of mercury, you may create problems that otherwise would not have occurred, such as:
- Possible damage to or weakening of teeth.
- Sensitivity or pain after amalgam replacement
- Financial problems.
