An introduction to CEREC CAD/CAM

All Ceramic restorations created chairside with textbook precision

For over 25 years now CEREC technology has allowed dentists to fabricate all ceramic

restorations chairside in a single appointment with ever increasing ease of use and

precision.

With ceramic restorations created chairside, natural occlusal surfaces in just one click and

uncomplicated digital optical impressions instead of uncomfortable conventional

impression trays, CEREC has definitely changed the dental practice for the better. This is

the opinion of an important group of people: your patients. 98% of all patients evaluate the

treatment results with very good or good. They particularly appreciate the natural

aesthetic appearance and the fact that it preserves healthy tooth substance, is metal-free

and there is no need for a temporary, as treatment can be carried-out in one appointment.

The experts agree. CAD/CAM with CEREC is no longer experimental technology, but a

technically mature mainstream treatment method with an impressive and proven record of

success. After 5 years 95-97% of CEREC crowns were still intact. The survival rate of

inlays and onlays was 90-95% after 10 years - a better success rate than the gold

standard!

Seeing CAD/CAM in a new light

All ceramic inlays, onlays, partial crowns, veneers as well as crowns and up to 4 unit

bridges are now possible. CEREC combines the advantage of a broad range of indications

with a particularly comfortable patient treatment in one appointment session.

CEREC AC Bluecam Acquisition - Fast, Easy, Precise

Precision and ease of use redefined

The new CEREC AC with the CEREC Bluecam captures highly detailed images using a

powerful blue light-emitting diode (LED). Rapid, easy imaging results in a quantum leap in

CAD/CAM precision, clinical reliability and efficiency. It is even possible to acquire difficult

inlay preparations 3-dimensionally with just a single image. Exposures for bridges and theneighbouring teeth are captured in auto mode and individual images are then

automatically superimposed together.

Even virtually inaccessible areas can be precisely acquired. The built-in shake detection

system, combined with the short capture time, ensure that images are acquired only when

the camera is absolutely still. The resulting precise 3-dimensional models permit a secure

construction of the restoration.

The new standard precision

The accuracy of the digital impression is absolutely decisive for the quality of the

restoration result. The basis for this is the CEREC AC acquisition unit with its innovative

optical concept. It delivers an unprecedented level of precision. * The high performance

diode emits blue light with a short wavelength. The resulting optical impressions are

extremely accurate. Even first time users can immediately achieve exceedingly precise

impressions. Additionally, CEREC AC fits easily into your treatment workflow.

*The result of a study carried out by Professor Dr Mehl (Zurich University 2008) measuring accuracy of up to

19m.

Compact camera

The CEREC Bluecam is based on the design of the highly successful CEREC camera,

which has proven itself many thousands of times in practical application. The compact

dimensions of CEREC Bluecam give you easy access to posterior teeth. With the help of

the CEREC camera support you can place the CEREC Bluecam directly on the teeth and

hence maintain the correct clearance for optimum optical impressions.

Automatic image capture

The camera automatically detects the right moment to trigger the exposure. All you have to

do is move the CEREC Bluecam step by step over the relevant area.

In this way you can acquire whole quadrants in a single streamlined operation.

Shake-free images

The built-in shake detection system, combined with the short capture time, ensures that

images are acquired only when the camera is absolutely still.

The CEREC 3D software automatically eliminates substandard images.

Uninterrupted power supply (UPS)

CEREC AC with the UPS option can be temporarily disconnected from the mains power

supply. This allows the acquisition centre to be wheeled easily from room to room even

during the milling process. Data can also not be lost during a brief power cut.

CEREC Biogeneric a single design procedure

The entire design process - including the generation of the biogeneric restoration proposal

- integrates itself seamlessly into your treatment workflow. The procedure is identical for

every indication - a major advantage over other CAD/CAM restoration methods.

1. Optical impressions of the prepared tooth and the antagonist are taken using

CEREC Bluecam.

A buccal exposure is also taken for the occlusion.

2. Registration of the preparation and the antagonist together with one buccal

impression.

CEREC Biogeneric - natural occlusions

An integral part of the CEREC 3D software: CEREC Biogeneric is very easy to use.

Irrespective of your previous CAD/CAM experience, the program features are quickly

learned and immediately applicable thanks to the standard procedure for every type of

indication.

CEREC Milling Units - Compact and Competent

Synchronised for success

From the digital optical impression until the final milling process all components of the

CEREC system are optimally synchronized with one another. The easy-to-use CEREC 3D

software, the automated milling process, the clinical benefits of all-ceramic materials,

treatment in a single appointment and positive feedback from patients - all these factors

combine to maximise your job satisfaction.

In addition, CEREC paves the way to increased practice earnings. Patient

recommendations after all, together with economic success, secure the long-term future of

your practice.

CEREC MC XL: precise, fast and quiet.

The increased speed and capacity of the CEREC MC XL are particularly advantageous if

you want to complete several restorations in one treatment session or create long-term

temporary bridges. The fast milling speed also facilitates the fabrication of conventionallycementable crowns made of lithium disilicate glass ceramic.

CEREC Clinical Studies

Scientifically secure

Are you still sceptical? Admittedly, CEREC sometimes sounds too good to be true. But on

the contrary, CEREC is very much a practical reality and to demonstrate this, we refer to

more than 250 scientific studies into the efficacy, biocompatibility and longevity of CEREC

restorations.

Your patients place their trust in your expertise. For your part, you can place your trust in

the expertise of renowned university professors and committed dental practitioners.

CEREC ranks as one of the most intensively scrutinised dental procedures - as evidenced

in numerous clinical studies and a wide range of scientific publications. The facts speak for

themselves. After 18 years, 84.4% of the CEREC chairside inlays and onlays are intact

and functioning. In cases where the inlays and onlays were adhesively bonded, thesuccess rate is between 90 and 95% after ten years. Follow-up examinations of around

5,000 restorations demonstrate that, in terms of their survival rates, CEREC restorations

are at least on a par with cast gold - and clearly superior to composite fillings.

The most important findings at a glance:

Fact: There are more than 25,000 CEREC users worldwide

Fact: They have already created more than 20 million CEREC restorations

Fact: CEREC Bluecam sets a new standard in measurement accuracy and delivers an

unprecedented level of precisionFact: After ten years, CEREC inlays and onlays achieve a survival rate of 90-95%

Fact: After five years, CEREC crowns have a survival rate of 95-97%

Fact: After nine years, CEREC veneers display an impressive survival rate of 94%

The facts are all in favour of CEREC:

An eighteen-year study of 1,011 inlays/onlays concluded:

Even large CEREC restorations display outstanding longevity. In many cases, defect-

oriented restorations and careful adhesive bonding provide the basis for dispensing withfull crowns.

A comparative study of the longevity of CEREC inlays and gold restorations

concluded: In terms of longevity, CEREC inlays are on a par with gold restorations.

Laboratory-fabricated ceramic restorations examined in this study were inferior in this

respect.

A study of longevity and production costs concluded: From a medical and economic

viewpoint, CEREC inlays are preferable to all other inlay types.



10/10

A comparative study to restoration quality came to the result:

Chairside produced CEREC inlays have less risk of developing enamel cracks in the

treated tooth as there is no temporary.

A study of adhesive systems concluded: Immediate treatment without temporaries has

a stabilizing effect on the tooth substance. The bonding technology takes into account abroader adhesive gap.

A study of optical measurement precision concluded: The CEREC Bluecam

generates digital optical impressions with an unprecedented degree of measurement

precision. Further information and details concerning the 250+ clinical studies of the

CEREC procedure are available under www.sirona.com.
