Step by step
Last week a good
friend of mine said
that she would
never have booked
a week-long sailing trip to the
Mediterranean if
she had known
that there was no shower on board.
“And will you go sailing again?”
I asked. “Yes, definitely,” she replied.
“It was great. And the missing shower
was no problem whatsoever!”
It’s a shame when we jump to
premature conclusions. And it’s a
shame when we reject new developments out of hand on the basis of
irrelevant criteria – something I experience frequently when dentists get
onto the subject of CEREC. Often it is
helpful to envisage a long-term goal.
Wouldn’t it be great if patients themselves demanded high-quality dental
restorations? If I could adopt a minimally invasive approach? If I could do
without impressions and temporaries?
If I could create all-ceramic restorations here in my practice? If I could
generate considerable additional revenues in just a few minutes?
When Professor Mörmann asked
himself these questions, there were
no answers on the horizon. This is
why he embarked on the development of CEREC. This was a long and
exacting task. But he took a first
courageous step. Why don’t you do
the same? We promise that you won’t
regret it!

The CAD/CAM way – a revolutionary
force in dentistry
LET US TAKE YOU BACK TO THE YEAR 1980. Amalgam was still the standard filling material. At the same
time, however, we at the Zurich Institute of Dentistry were experimenting with alternative tooth-coloured, prepolymerized composite inlays designed for adhesive bonding. Ceramic – the ideal material for long-lived dental
restorations – was hardly ever used for inlays and onlays, as it involved too much work in the laboratory and
was too prone to fractures. The time was therefore ripe for a new therapy approach.
T
he successful outcome of our inlay
experiments – i.e. the perfect bond
with the tooth – raised a new problem. We needed to find a method for
the rapid production of inlays.
During a visit to the Advanced
Technologies Laboratory in Seatlle
(USA) I succeeded in recruiting a
friend of mine, Dr. Ing. Marco
Brandestini, a graduate of Swiss
Federal Institute of Technology in
Zurich. Together we thought up a
dental CAD/CAM system that was
capable of creating a three-dimensional image of the cavity, designing
the inlay, and milling the restoration
from a high-strength ceramic material. The goal was to create a system
that enabled dentists to produce and
place a ceramic restoration in a single treatment session – without the
need for a conventional impression,
a temporary or a second appointment. We chose the name “CEREC”,
short for “Computer-aided CEramic
REConstruction”.
In the beginning there was a fascinating idea
Before CEREC finally took shape,
five years of hard pioneering work
were required in the area of image
acquisition, software programming
and milling technology. In other
words, we had to combine optoelectronics, IT, mechanical engineering,
control technology as well as traditional dental skills.
We decided to call the 3D image of
the cavity the "optical impression".
This was supposed to take place in a
matter of seconds. For this purpose
Brandestini designed the CEREC 1
intraoral camera. The exposure angle
had to correspond to the insertion
access of the restoration, and the
image had to be displayed on the
monitor instantaneously for checking
purposes. A telecentric beam path was
chosen for the 3D measuring process
(4 x 40 milliseconds). We ordered the
lenses from an optical specialist and
then glued them together ourselves in
order to create the first functioning
camera. The depth of field was 10 mm
– sufficient to accommodate deeper
cavities. To acquire the 3D data we
decided to apply the principle of active
triangulation. In other words we projected a grid of light and dark lines
onto the cavity and then measured the
depth-related shifts with the help of a
CCD video chip at a resolution of 50
m. Today, such high-definition video
chips are a mass commodity. But back

The term “weblog” (often abbreviated “blog”) describes a new type of
online diary. In connection with the
20YC symposium the CEREC marketing team has decided to experiment
with this very direct and personal
mode of communication. The goal is
to inform CEREC users and prospective customers about the history of
CEREC and about the forthcoming
symposium. Every day new pictures
and contributions are posted on the
blog. And once a week a new story

He programmed the operating system
of CEREC 1 (COS 1.0) in accordance
with our specifications, taking into
account the three basic CAD/CAM
parameters (the bottom line, the equator, and the proximal and occlusal
cavity margins). The next problem
was to find a suitable drive system for
the diamond grinding wheel. To this
end we produced a miniaturized version of the Pelton turbine used in
Swiss hydroelectric power stations.
Often the answer is on one’s doorstep!
To begin with we fired the ceramic
blocks in our own laboratory – until
we established a working relationship
with VITA Zahnfabrik, a highly qualified supplier of Mark I feldspar ceramic. In September 1985 CEREC 1 was
finally up and running. We assembled
each of the modules ourselves, from
beginning to end. The first CEREC
chairside ceramic inlay was produced
on 19 September at the Institute of
Dentistry at Zurich. The very first
patient I treated was Alain Ferru, our
computer programmer. His tooth 27

America than on this side of the
Atlantic, over 2,000 European
CEREC users have meanwhile
joined the Silver Club. In
addition to making significant
savings on CEREC updates and
upgrades, the Silver Club members qualify for numerous other
benefits.
For example, Pieter Le Roux
from Dunstable is especially
pleased about the ten percent
reduction on admission to the
20YC symposium in Berlin.
“I’ve already recouped my
membership fee for March,”
says Le Roux. “And perhaps
I’ll obtain a vital piece of information which is so valuable that
it can’t be measured in terms of

session. Bonding took place as follows: firstly the cavity margins were
etched; the surfaces were then primed;
finally the restoration was fixed in
place with the help of a composite
material normally used for premolar
fillings. The adhesive bond proved to
be resistant to penetration.
Capitalizing on innovation
From the outset our team was convinced that the rapid chairside fabrication
of ceramic restorations would be a
very attractive proposition for dentists
and patients. Experiments had already
been performed indicating that it was
possible to create top-quality adhesively bonded restorations. After CEREC
had proved itself as an “inlay machine” it was clear that the system
should be continuously refined and
developed – up to and including the
ability to fabricate ceramic bridgeworks. This in turn necessitated the
development of aesthetic, highstrength machinable ceramic materials.
Co-operation with Sirona placed
the project on a solid foundation. The
company is absolutely convinced of
the future potential of the CEREC procedure. To date, dentists all over the
globe have placed more than 12 mil-

lion CEREC restorations – a clear indication that CEREC is fully accepted in
professional circles. CEREC has become the driving force behind dental
CAD/CAM technology the world over.
We and Sirona have continuously
adapted the CEREC procedure to the
requirements of patients and dentists.
Today, a dentist does not need to be a
computer expert in order to integrate
CEREC into his or her practice workflows. The current version of the
CEREC system ensures maximum
comfort for the patient – and optimum ease of use for the dentist. This
high-tech procedure is the passport to
enhanced job satisfaction, as manifested in enthusiastic responses of
patients. It’s a great feeling to bite on
the highly polished CEREC restoration and to trace its smooth contours
with the tongue. “It’s just as if it were
my own natural tooth.” A glance in the
mirror reinforces this sense of satisfaction and trust. Thanks to CEREC,
dentists all over the industrialized
world are in a position to offer
patients convincing treatment alternatives and to generate appropriate revenues. Patients are willing to pay more
for high-quality dental treatment services.
My personal clinical experience
since 1985, plus numerous scientific
surveys of dental practices and clinics,
have confirmed that patients are right
to place their trust in CEREC restorations. More and more patients are
now willing to depart from the “gold
standard” and are choosing CEREC to
replace existing metal-alloy and gold
restorations, although these are the
product of perfect workmanship. The
demand is now for restorations that
are natural in terms of form, function
and colour. Indeed, we could even talk
about a new “natural” standard.
The achievement of this natural
standard for dental restorations is the
guiding principle behind CEREC and
behind my/our efforts in this area. ■
Prof. Dr. Werner Mörmann, Centre for Dental and
Oral Medicine at the University of Zurich
Studies confirm the durability of CEREC
20 YEARS OF CLINICAL EXPERIENCE. Treatment room 37 at the Zurich University’s Institute of Dentistry
will go down in history. It was here that, 20 years ago, the first-ever patient received a CEREC inlay.
T
he name of this patient was Dr.
Alain Ferru. In the course of a single treatment session Professor
Werner Mörmann created the inlay
using CAD/CAM techniques and
then bonded it adhesively to the
patient’s tooth. At the time dental
professionals were unanimous: this
restoration will never last. “You could
throw a hat through the marginal
gap” and “A piece of ceramic awash
in a sea of composite” were just two
of the more friendly comments by
opinion leaders and university professors. They were arguing from the
now obsolete perspective of metaloriented dentistry. For this reason
most clinical studies concentrated on
the marginal gap width – with disastrous implications for CEREC, as it
appeared at the time.
However, a small but ever larger
group of clinicians was convinced
that adhesively bonded inlays and
onlays could produce durable outcomes. Professor I. Krejci, for
example, examined the wear resistance of industrially fabricated
ceramic blocks and came to the conclusion that CEREC restorations are
virtually indistinguishable from
natural tooth enamel. N. Martin and
N. M. Jedynakiewicz systematically
evaluated 15 clinical studies performed over the period 1986 to 1997.
This revealed a 97.4 percent survival
rate for CEREC. The average observation period was 4.2 years.
A further long-term evaluation
was carried out by B. Reiss und
Professor W. Walther: in a private
dental practice 299 patients received
a total of 1,010 CEREC chairside restorations. After a period of ten years
the survival probability rate was 90
percent. Large restorations such as
onlays and partial crowns performed

just as well as two-surface inlays.
Premolars performed slightly better
than molars; and vital teeth produced
better long-term results than nonvital teeth. T. Otto and S. De-Nisco
devoted their attention to the same
question and monitored 187 CEREC 1
restorations over a period of ten
years. The survival probability rate
was 90.4 percent. Professor R.
Hickel and J. Manhart from Munich
University studied the scientific literature published during the past ten
years and calculated the annual percentage loss rates of the materials
used for Class I and Class II cavities.
Even in the worst cases, the CEREC
restorations were 25 percent better
than gold fillings. A particularly interesting follow-up investigation was
carried out by A. Posselt and
Professor T. Kerschbaum. They took
as their basis 794 patients who had
received 2,328 CEREC chairside restorations in a variety of different dental practices. After nine years the survival probability rate was 95.5 percent.
The advent of CEREC crowns has
spawned a variety of university
research projects. A. Bindl and
Professor W. Mörmann, for example,
fabricated 208 Vita Mark II crowns
and bonded these to a variety of
different preparations. After five
years molar crowns bonded to
“classic” preparations displayed a
survival rate of 94.6 percent. The
equivalent figure for premolars was
97 percent. These survival rates
correspond easily to those of conventional metal-ceramic crowns.
Another interesting issue is the longterm performance of veneers. Prof.
T. Kerschbaum and K. Wiedhahn
performed a follow-up examination
on 617 veneers over a period of nine
years. The Kaplan-Meyer survival
rate was 94 percent in the case of
veneers applied to natural teeth, and
91 percent in the case of anterior
veneers used to repair crowns and
bridges. In addition, there are a
variety of other scientific studies
relating to adhesive bonding, aesthetics, occlusal design, and practice
integration. As far as the last of these
topics is concerned, one study has
shown that a dentist can cut his
workload by up to two thirds by
delegating various processing steps
to the assistant. A whole range of
publications indicate that CEREC
is at least on a par with gold restorations. Indeed, a sneak preview of the
latest statistical evaluations (ready for
presentation at the 20YCs symposium) indicates that CEREC has
already surpassed the established
■
“gold standard”.

TIPS FOR VISITORS TO BERLIN. When CEREC was unveiled to the international public, Berlin was still a
divided city. Since then Germany’s largest city has changed a lot – and acquired an even greater charm than it
had before.
E
ven those who know Berlin well
find that the city always has something new to offer: 170 museums, the
Philharmonic Concert Hall, dozens
of theatres and opera houses and
fashionable clubs offer a constantly
changing program of entertainment to
suit every kind of taste. The legendary
“KuDamm” (Kurfürstendamm), Friedrichstrasse and the redeveloped city
centre are a shopper’s paradise.
Countless cafés, bars and restaurants
in every price bracket offer a bewildering choice of international and local
German cuisine. For all those who
plan to relax and see the sights after
the 20th anniversary CEREC symposium, or even spend a long weekend
in Berlin, we’ve got a few tips to help
you make the most of your time in
the city.

Since the fall of the Berlin
Wall, the new Federal capital
has blossomed as a major
focus of European cultural life.
Culture and sightseeing
Jewish Museum, Berlin (Lindenstraße
9-14, U1/6 Hallesches Tor): The zigzag forms of Daniel Libeskind’s iconic
building, housing a permanent exhibition on the turbulent history of the
Jews in Germany, has captured the
public imagination ever since its opening in 2001. Chinese Garden (Eisenacher Str. 99, Marzahn, bus stop Erholungspark Marzahn): Europe’s biggest Chinese garden features a landscape of rocks with waterfalls, a lake
with bridges and ornate pavilions in
the Chinese pagoda style. Neue National-
shop is an Aladdin’s cave for fashionistas,
packed with second-hand pieces, designer clothes and the latest collections at bargain prices. Hackesche Höfe (Rosen-thaler Strasse, Berlin-Mitte; U Wein-meisterstrasse, S Hackescher Markt): A favourite
place to buy unusual shoes, designer
fashions and jewellery – popular with
locals and tourists alike.
The décor may be plain to the point
of austerity, but the cuisine demands
– and deserves – one’s full attention.
Borchardt’s (Französische Str. 47,
Berlin-Mitte, U Französische Strasse):
A real institution on the historic
Gendarmenmarkt. A favourite haunt
of business executives and senior
political figures.

Always the right material
ABSOLUTE DEPENDABILITY. Dentists, labs and patients all benefit
directly from our close links with material manufacturers.
C
eramic materials are not all the
same. They differ considerably in
terms of aesthetics, fracture resistance
and machining characteristics. This
means that dentists can choose the
right material for every clinical indication. To ensure optimum quality it is
important that the ceramic material is
perfectly matched to the CAD/CAM
system. For this reason Sirona has
maintained long-standing working
relationships with three leading
manufacturers of dental ceramics:
Vita Zahnfabrik, Ivoclar Vivadent and
3M Espe.
Different ceramic blanks are deployed depending on the specific application involved. After milling zirconium oxide ceramics, for example,
need to be sintered in a high-temperature furnace. They are used mainly
for bridge frameworks. By contrast,
fine-structure ceramics can be polished and characterized immediately
after milling. They are therefore wellsuited to a broad spectrum of chairside applications. There is a growing
trend towards multilayered ceramics
with differing degrees of translucency. They save time – and are indistinguishable from natural teeth, even to
practised observers.
All the ceramic materials have
stood up to the test of practical application. Long-term studies (over
periods of up to 18 years) indicate
that CEREC ceramics are at least
as durable as traditional metal materials.
CAD/CAM restorations made of
metal and composite materials
Regardless of which material the dentist
chooses, he or she can be sure that the
ceramic is perfectly matched to the CEREC
system.
Via infiniDent – our centralized
manufacturing service – inLab users
in Germany and France are now in a
position to offer CAD/CAM restorations made of various metal alloys.
Dentists in the USA have the option
of creating CEREC restorations from

AN SWE RS TO YOU R QU E STION S
We’re all familiar with the problem. You have just listened to a lecture and want to ask
an important question. But there are 1,000 people in the hall and you’re afraid to speak
up. Such missed opportunities are a shame. Perhaps your question could have made a
major contribution to the scientific debate. For this reason Sirona has developed a special
mode of communication for the 20YC Anniversary Symposium in Berlin.
Fifty experienced CEREC specialists from all over the globe will be on hand throughout
the symposium to answer questions about CEREC – both theoretical and practical.
Attendees are welcome to bring along models, which can then be discussed directly at
one of the CEREC systems installed at the congress hotel.
The CEREC specialists can be identified by their lapel badges. They will be able to
communicate with each other via mobile phone if a second opinion is required. In the
unlikely event that your query cannot be answered during the congress you will automatically qualify for a special raffle. It goes without saying that the CEREC Team will
be in Berlin to help and advise.

Wanted: Poster designs Grand anniversary gala
T
he 20-year CEREC Anniversary
Congress gives practitioners a
unique opportunity to tell their own
personal CEREC stories to a wider
audience. The presentation of posters highlighting recent research
work on CEREC applications has
been organized by Sirona with the
idea of offering a balanced mix of
scientific information and personal
narratives. A scientific committee
under the direction of Professor Dr.
Werner Mörmann will select 40 posters from all the designs submitted.
The principal authors of these posters will get a 50 per cent discount on
their Congress fees, including the
cost of their ticket to the evening
gala. But that’s not the only reason
for taking part. The cost of entering a
poster design is much lower than it is
for conventional poster exhibitions,
because entrants are not required to
submit their design in final printed
form. The winning entries will be on
view on the second day of the
Congress in the form of a slide show
running on a bank of plasma flatscreen displays. Those wishing to
take part in the poster presentation
should simply send in their entry by
e-mail as a Powerpoint or pdf file, or
else send a CD-ROM to Quintessenz
Verlag. Guidelines on poster and lettering sizes and on general layout
can be found online.

AN EVENT TO REMEMBER. Serious scientific discussion in congenial surroundings: the 20YC symposium is
not to be missed on any account.
she has only chipped a front tooth.
Julia’s regular dentist, Dr. Hartmann
– not a CEREC user, and madly in
love with her – suggests a conventional crown as the appropriate treatment, for not entirely unselfish reasons. This requires several appointments – which means he gets to see
Julia more often. Julia on the other
hand dreams only of Michael, who
would like to attend the 20YC symposium in Berlin. He looks forward to
hearing speakers from the USA and
all over the world, who have had a significant influence on the history of
dentistry. He’s also hoping to pick up
some useful tips from older colleagues. Will CEREC help Julia to win
Michael’s heart? Now read on .... The
sequel to the story will be sent to individual CEREC users as a mailing, and
from February it will also be posted

BIG POSTER PRESENTATION IN BERLIN. CEREC practitioners are
invited to submit a poster of their own design, reflecting their own experiences, for the 20YC Anniversary Symposium. Suggested themes might
be time measurements, integration models or particularly interesting
treatments – or indeed anything else to do with CEREC or inLab.
Recapturing the gracious living of the 1920s: a stylish
setting for serious science at the 20YC symposium.
prise package of fun and excitement.
Under the motto “Feel the Passion”,
the organizers have planned an action-packed program of high-class
entertainment. Sirona has certainly
picked the ideal location: the Tempodrom, next to the historic Anhalt
Station, is one of Berlin’s premier
venues for unusual and exotic events.
The action will be everywhere: in the foyer, in the
bars, in the lounge and in
the main arena. There’ll
be the occasional speech
or two, of course. The history of the CEREC and
inLab CAD/ CAM systems will be graphically
illustrated in a gallery of
pictures. But this is party
time first and foremost –
an opportunity to escape
from the familiar daily
routine and mix business
with pleasure in an evening of amusement, high
spirits and – yes - passion.
Enthusiasm is catching
For 20 years now CEREC has
been captivating dentists the world
over – and the Congress organizers
want delegates to feel the fascination
and experience it for themselves.
They’ll find that the enthusiasm of
the global CEREC community is

catching.
