In the past, your dentist would have to take alginate impressions of your teeth and send these off to a dental lab in order for your crown to be created. Thanks to the CEREC system, we can now offer same-day crowns, saving patients time and hassle.What is CEREC and what is involved with the procedure?
CEREC is a state-of-the-art system used to design, create, and fit a crown in a single appointment.
Preparation – Your dentist will prepare your tooth in the normal way, removing a specific amount of tooth matter to ensure your new crown will fit comfortably over the top of your natural tooth.
3D images – Following this, a 3D image of your tooth is taken using the CEREC Ortho software – this provides a foundation for the design of your crown.
Creating your crown – Once your dentist is happy with the design of your crown, the template will be sent to an onsite milling machine that will craft your crown from a high quality ceramic block, drawing on the measurements and dimensions acquired from the 3D images. You and your dentist will have decided upon a shade for your crown beforehand.
Fitting your crown – Once your crown has been milled, it is ready to test-fit and your dentist will make any necessary amendments before permanently fitting it. It will also be glazed and polished in order to give it the most authentic finish possible.
Benefits of the CEREC system
Many patients are put off by treatment that requires a lot of chair time and multiple dental visits. The traditional approach to fabricating crowns would generally take a minimum of 2 appointments over 2 weeks, during which time you would be fitted with a temporary crown. As CEREC crowns are designed, created, and fitted in a single appointment, there is no need for us to fit you with a temporary crown and chair time is reduced as the impressions are taken digitally.
The CEREC Ortho software allows your dentist here at Keppel Advanced Dentistry to see a 3D digital model of your tooth before treatment even begins. This allows us to discuss the results directly with you and gives you an idea of what to expect from the treatment.
A further benefit of digital impressions is that patients are spared the discomfort of alginate impressions, which notoriously induce a gag reflex in many people. CEREC incorporates the CEREC Omnicam, which is used to take digital impressions of your teeth and is lightweight and easy for your dentist to handle. This allows them to take fast and accurate impressions the first time around. The Omnicam’s high level of accuracy also means your crown is 100% bespoke and fits amongst your existing teeth perfectly.
Only 1 set of local anaesthetic injections are needed – although this may not be a significant for some, there are many people who suffer from extreme dental phobia and who will actually put off having the treatment they need because it involves injections. Patients who are anxious about the prospect of anaesthetic will be pleased to hear that only 1 set of these injections are necessary.
