CEREC is a manufacturing concept - a treatment concept - a medical device, that allows the dentist to produce crowns, inlays and veneers in one single procedure! Also small bridges made of high-strenghth, high esthetic ceramic can be produced without taking annoying impressions and instable temporaries.

2. What can CEREC do?

Natural teeth, even highly destructed ones can be treated with inlays, onlays and crown made of tooth-colored ceramic, making the restoration practically invisible. Front teeth can be enhanced using thin ceramic veneers or if necessary can be capped with full ceramic crowns. Old crowns that have lost their esthetic potential can be easily replaced with a perfect full-ceramic CEREC restoration. Small gaps between teeth can be closed with a full-ceramic bridge. All these procedures can be done exclusively in one visit . Even deficiencies on old crowns or bridges and be safely repaired.

3. What materials are being used with CEREC?

The world-wide most renowned manufacturers of ceramic materials have special CEREC - ceramic blocs in their portfolio. Depending on individual necessary stability and esthetic a number of different materials are available. (glas- or feldspatic ceramic, disilikate or zircon-oxide). lFor each material a great number of different colors is available, covering all different individual situations. If necessary all ceramic material can be customized to get a individualized color. Specialty treatments (i.e., long-term temporaries on implants) can be done using CEREC composites.

4. How does a typical CEREC treatment look like?

Normally the tooth is being anesthetized and then being treated (removing caries and reshaping) making sure to save as much tooth structure as possible. Within seconds the dentist will take a 3D picture using the CEREC camera. In front of the patient the restoration is being designed "on-screen". Guided by computer the precision milling-unit will produce a well fitting restoration in less than ten minutes. Then the restoration is being fitted and cemented. Followed by contouring the surface and checking the bite. The ceramic is polished to a high-gloss, and mimics the surrounding tooth structure perfectly.

5. How long does a typical CEREC treatment take?

A CEREC treatment is complex and consists of several steps. Typically It takes about 60 minutes for a single inlay. Multiple restorations will prolong the treatment accordingly. Since the treatment is interrupted by several pauses due to construction by the dentist and milling the restoration, even longer treatments times are not considered strenuous by the patient.

6. What does "chairside" mean?

When producing a crown in a conventional way, it is necessary to take impressions and fabricated temporaries, so that the crown can be done in a dental laboratory. 'The CEREC technology takes an "optical impression" using the CEREC camera in the patients mouth while being in the dental "chair". Also the computerized construction and production of the restoration is being done in the direct vincinity of the chair. That's why it is called "chairside" which is alot more convenient and comfortable for the patient.

7. What are the advantages of a CEREC treatment?

The advantages are: - less effort for the patient (1 appointment) = time saving - annoying dental impressions are being avoided = convenient - no temporaries necessary = cost effective - esthetic adjustments can be done immediately = highly esthetic - the prepped tooth surfaces are not being infected with impression material and temporary cement, the margins are better sealed = cleaner - since no temporaries are necessary, bactera cannot infect the tooth = safer

8. How long does a CEREC restoration last (inlay, crown)?

This question can onlybe answered by looking at the statistics. CEREC is the best reviewed procedure in restorative dentistry. The longest follow-up studies have been conducted for close to 20 years. Statistically the success rate is 86% after 18 years. In dentistry a procedure is considered successful when the failure rate per year is less than 1%, thus 90% of the restorations should be still intact after 10 years. In comparison, CEREC restorations are just as successful as gold restorations and significantly more successful than ceramic restorations produced in a dental laboratory.

9. Can CEREC also do fixed bridges?

Generally speaking: YES. - Small bridges can be done chairside, Lager bridges need zirkonoxid ceramic as a base material for higher strength. The necessary "firing" time in the ceramic oven takes about 8 hours, thus making a chairside procedure not sensible. Good planing makes it possible to produce such a bridge in one day.

10. Can CEREC be done on implants?

Just like natural teeth crowns can also be incorporated on implants using the CEREC method.

11. Can defective baby-teeth also be treated using the CEREC method?

In principle: YES - Due to the prolonged time in the dental chair it seems unwise to stress like patients with the procedure. Other well-established procedures that can be done in less time seem more appropriate.

12. Can all CEREC treatments be done without taking an impression?

All CEREC procedures, be it one or more single teeth, can be treated without taking conventional impressions. When bridges are being planned impressions and casts are still necessary. Research is on the way to make impression-free bridges a reality.

13. How long does CEREC exist?

In 1985 the first inlays were produced and cemented by Prof Werner Mörmann in Switzerland. The technology was introduced and made available to dentist by the German Siemens company in 1988. After a spin-off at the end of the 90's the Sirona company (Germany) continued the research and development. In January 2009 the fourth generation was introduced (CEREC AC and CEREC MC XL milling machine). With the latest generation hardware the basis for the impression free practice laid.

14. For what patients is the CEREC method advantageous?

CEREC is perfect for those who want a metal-free, ceramic restoration, trying to preserved as much tooth structure as possible. The impression free procedure and the lack of temporaries makes it the ideal treatment for those who appreciate the one-appointment-only treatment.

15. Is a CEREC treatment painful?

Just like every other dental treatment with fillings or crowns, minor discomfort is possible on the day of the procedure. Normally it will be gone by the next day. Since the definite treatment is done in one procedure, the bacteria have little chance to infect the unprotected tooth surface. The chance of an irritation of the nerv is less likely than with conventional procedures.

16. Does CEREC require a specialized education for the dentist?

When buying a CEREC unit the dentist is given the opportunity to visit a two-day basic training course. Continued education courses in this topic are being offered by relevant dental organisations (i.e., world-wide operating International Society of Computerized Dentistry (ISCD)) A profound knowledge base in CEREC is a cornerstone for a successful CEREC treatment.

17. How many dentist work with CEREC?

In Germany - the homeland of CEREC - 8,000 dentists own a CEREC unit. A similar high number can be found in the United States. In all developed countries, CEREC has achieved a respected place in modern dentistry

18. What is outstanding about the CEREC specialists of the "German CEREC Dental Team" at the Habib Clinic Dubai?

The CEREC dentists at the Suleyman Al Habib Clinic, the German CEREC Dental Team (GCDT), are world-wide renowned CEREC experts. Every one has more than 10 years of experience with the system and is a ISCD Certified CEREC trainer, thus also training other dentist. They are lecturing and undertaking live-demonstrations using CEREC world-wide. They all have profound knowledge about the system, since they are all in close contact with Sirona R&D as beta-testers supporting them with their expertise. Combined this group posesses a CEREC know-how, that's unrivaled world-wide.
