Smile with CEREC


When it comes to cutting edge technology, the latest techniques and making dental treatment affordable, Changing Faces specialises in preventative and restorative dental care for the whole family.

The  friendly team of dentists and hygienists are based in a purpose-built clinic which is a first for New Zealand and reflects a fresh approach to dentistry.

The highly-trained staff offer solutions for all dental requirements, whether diagnostic, preventive, restorative, cosmetic, myofunctional, early orthodontics and orthopaedic, or surgical services.

This month under the spotlight, we take a look at CEREC.

What is CEREC?
CEREC stands for “Chairside Economic Restoration of Esthetic Ceramics”, or “CEramic REConstruction”
CEREC uses digital imaging technology to produce a 3D 1:1 scale virtual model of the teeth for designing a restoration through software which communicates with a milling unit to carve a restoration out of a block of dental ceramic.

The latest advances have seen the development of the Omnicam – an intraoral video camera which produces full colour images which are seamlessly stitched together to produce an exact replica of the object being scanned.

What is unique about it?
CEREC permits the indirect restoration of teeth without the need for impression material. Restorations can often be completed in a single appointment without the need for temporaries,  which means that designs which were once considered too minimalistic are now viable.

What does it mean for the customer?
Fewer appointments, increased comfort and convenience, restorations constructed from the latest materials, preservation of tooth structure.

What is it used for?
In addition to constructing indirect restorations, the CEREC machine can be used for case presentations with smile design software, which can provide a proposal for review prior to cosmetic work being undertaken. It can send information to laboratories through portals in cases where a technician’s expertise is required. New developments allow for restoration of implants and orthodontic applications.

What are the advantages?
The advantages are elimination of impression material, greater customisation, and more conservative preparations meaning less damage to tooth structure. Indirect restorations such as those produced by the CEREC machine do not undergo dimensional changes in the mouth like direct restorations which means that the chance of fracturing tooth structure due to stresses acting on the tooth is greatly reduced.

Who can benefit from it?
People who find it difficult to find the time for multiple appointments can benefit from single appointments to complete indirect restorations. People who have problems with gagging and can’t tolerate impression material can avoid the discomfort of having an impression taken.

What does it cost?
Prices vary according to the materials used but the costs of a CEREC are substantially less expensive than standard crowns and inlays.
