Las Vegas Cerec Dentist

Are CEREC restorations suitable for anterior teeth? Quite unjustifiably, some dentists still think that CEREC delivers inferior aesthetic results. The software, hardware and materials have undergone such rapid development that it is a matter of personal preference – rather than aesthetics – whether anterior restorations are produced on the CEREC system or delegated to a dental lab. In both cases the results are truly
convincing. The new CEREC 3.80 Biogeneric software reconstructs the natural tooth morphology at the click of a computer mouse. All you have to do is mark the preparation margin and click “Next”. The software then takes care of the rest. The Biogeneric software is based on the realization that, like a fingerprint, each human tooth is unique. In addition, it exploits the morphological correlations between an individual patient’s teeth. In other words, the software extrapolates the natural shape of a tooth from the data derived from another, intact tooth in the patient’s mouth. When performing anterior restorations you can now reap the benefits of the new VITABLOCS RealLife for CEREC. The unique three-dimensional block structure perfectly emulates natural anterior teeth. With the aid of the CEREC MC XL milling unit you can create highly aesthetic veneers as well as full and partial crowns in just a few minutes.

1. CEREC 25
CEREC 25th Anniversary Celebration
In 1985, a patient at Zurich University was treated using the very first CEREC inlay. In the meantime more
than eight million patients worldwide have received a total of 20 million CEREC restorations. CEREC is no
longer an experimental technology. On the contrary, it has become a universally recognized treatment
procedure. We look back on this success story with great pride.
In the course of this success story we marked CEREC’s 10th anniversary in Zurich. The 20th anniversary
celebrations took place in Berlin and Las Vegas. This year the entire CEREC community throughout the
world will gather in Las Vegas from 26 to 28 August 2010 in order to celebrate CEREC’s silver jubilee.
Taking part in the CEREC 25th Anniversary Celebration will certainly pay dividends. It is your chance to meet the “Who’s Who” of computerized
dentistry. Leading international experts will deliver more than 50 lectures.
On the second day of the scientific congress we will open a poster exhibition, where academics and dentists who focus on CAD/CAM in general
and CEREC in particular will present their investigations and clinical findings. The terms and conditions for the poster exhibition are available at
www.cerec25.com
The city of Las Vegas is a fascinating venue. Further information is available at www.vegas-online.de For more than 40 years Caesars Palace
has been one of the city’s top attractions and provides the perfect setting for CEREC 25.

DÜSSELDORF. – Digital impressions, biogeneric occlusion design, virtual whole-arch
reproduction, rapid prototyping of dental models, computer-manufactured veneers – these
are just some of the topics featured in recent scientific articles and lectures and now on
their way into practical application. These and other issues were on the agenda at the
well-attended symposium of the CEREC Masters Club in Düsseldorf on 11 and 12 June
2010. The CEREC Masters Club is a group of university academics, dentists and dental
technicians who have pioneered digital technology in dental practices and laboratories
and have presented their valuable experience in lectures and publications. The findings
presented by this interdisciplinary working group prove that – 25 years after the creation
of the first computer-manufactured ceramic inlay – the CEREC system has lost none of its
innovative power and remains the worldwide driving force behind dental CAD/CAM
technology.
2. CEREC day – 2010
25 years old and geared up for the future
CEREC symposium looked ahead to the future on the basis of tried-and-tested CAD/CAM techniques.
PD Dr. Andreas Bindl, Zurich, who was involved in the development and testing of the CEREC Bluecam imaging system, lectured on the topic
of “Chairside Methodology”, with special reference to the precision of intraoral scanners. In this context he described the interaction of the
CEREC AC acquisition unit and the GALILEOS CBVT system in the field of implant prosthetics. According to Bindl, the angled imaging function and the anti-shake function significantly improve the quality of intraoral scans, as well as the precision of digital impressions. This has been demonstrated on the basis of comparative measurements performed on a stationary, calibrated reference scanner. Whole-arch scans are feasible in principle. However, the deviation tolerance in the terminal area of the arch does not yet correspond to CEREC quality standards. After the necessary software adjustments have been made, however, whole-arch scans will in future belong to the standard CEREC repertoire. Monolithic posterior CEREC crowns made of lithium disilicate have proved successful in the area of implant prosthetics. According to Bindl, the
mobility of the endosseous post when exposed to chewing forces does not pose a risk to monolithically milled, adhesively bonded crowns. Bindl went on to discuss the networking of CEREC and GALILEOS. The interaction between these two systems offers decisive advantages: firstly, the three-dimensional visualization of the osseous structure and the soft tissue leads to enhanced diagnostic accuracy; secondly, the
tomographic X-ray, the planned endosseous post and the superstructures can be combined in a single screen image. Thanks to the networking of CAD/CAM and CBVT, surgical interventions are more reliable and the outcome can be predicted exactly in advance. In addition, the process of implantation is faster. Dr. Andreas Kurbad, Viersen, reported on his experience with biogeneric occlusion design for partial crowns and crowns. Although he at first missed the dental database, the longer he used the new V3.80 software the greater was his confidence in the automatic reproduction of patient-specific occlusal surfaces. Kurbad confirmed that the individually computed restoration proposal is superior to the database tooth in
terms of function. In addition, hardly any fine tuning is required when the restoration is finally placed. In many cases, minor contact problems can be eliminated by means of polishing paste. According to Kurbad, this is subject to the precondition that the reference tooth contains sufficient information. Additional angled images deliver enhanced morphological precision beneath the crown equator.
The dental technicians Kurt Reichel and Sonja Ganz, Hermeskeil, talked about the benefits of CEREC Connect to dental laboratories. Dental labs are now in a position to become actively involved in the fabrication of conservative dental restorations and can produce inlays, onlays, partial crowns, veneers and monolithic crowns with high precision and tailor-made aesthetics. An SLA model is required for crowns and bridges with fused-on ceramic facings. Only in this way is it possible to apply the facing layer by layer. Numerous dental practices have confirmed that only minimal adjustments are required when the frameworks are fitted onto the SLA models. Reichel recommends intraoral try-ins, as this is the only way to arrive at a definitive evaluation of how the restoration fits the residual tooth. In addition, models generated via CEREC Connect can be fine-tuned using a standard articulator and a split-cast adapter, subject to the condition that a whole-arch scan hasbeen acquired. The RealLife feldspar ceramic blocks reproduce perfectly the cervical-incisal chroma gradation and pigment density of a natural tooth. This new addition to the VITABLOCS (VITA Zahnfabrik) portfolio is ideal for highly aesthetic restorations. Consisting of a dentine core and an enamel shell, the three-dimensional block structure simulates the arc-shaped shading progression from the dentine towards the incisal edge. In Reichel’s opinion anterior crowns made of this material are aesthetically superior to layered ceramic facings. Dental technician Sonja Ganz described the features of the new inEos Blue scanner. The implementation of the blue-light imaging system of the CEREC Bluecam has led to improved measuring performance. The XY table permits the model to be moved in all directions and angles.
The model holder boasts a ball joint to facilitate whole-arch scans. A removable slide facilitates grid-pattern scans. The 3D image catalogue immediately displays the scanned areas of the model. It is also possible to scan conventional impressions – i.e. to do without a model entirely. Undercuts are detected by means of angled images. According to Ganz, these features result in significantly enhanced convenience,
regardless of whether the inEos Blue is deployed as a stand-alone module in combination with an in-house milling unit or as a relay station for an external milling centre. Following this, dental technician Kurt Reichel presented new veneering techniques for oxide ceramic frameworks designed to avoid veneer fractures. It is now possible to produce CAD/CAM feldspar veneers which are then sintered onto anatomically sized frameworks. This method
avoids the tensile stresses which frequently occur at the interface between the framework and the manually layered veneer.
3. CEREC Biogeneric
Biogeneric: The New Workflow Tips and tricks for CEREC 3D Software V3.80
With the buzz around CEREC Biogeneric, with talk of mathematical algorithms and clinical studies, it's possible to lose perspective on the core benefit: it's really all about you, the user. CEREC Biogeneric is yet another step – albeit a very large one – on our never-ending path to improve the results you deliver to your patients and to make it easier to achieve these results. Judged on this scale, Version 3.80 is probably the most important software upgrade since the first CEREC 3D version. The reason is simple: from now on, there is only one workflow. Whether Inlay/Onlay, Veneer, Crown or Bridge; regardless of correlation or replication coming into play: One single unchanging path leads you from start to finish. Here are some guidelines on the new workflow to help you get started working with CEREC Biogeneric:
Providing input information With the removal of the dental databases, the software has to create each restoration "from scratch". CEREC Biogeneric is more than capable of this feat, but you'll want to be sure to provide ample information to ensure a good proposal. The software selects one or two "source" teeth
and uses all the information it can get from them. In Biogeneric mode, the approximal neighbors are the default source:
The distal neighbor is the preferred source for posteriors
The mesial neighbor is the preferred source for anteriors
If more than half of the data from the preferred neighbor can be gained, that's all the algorithm needs to create a custom-fit proposal. If too little data is available from the preferred neighbor, it is supplemented with data from the other neighbor (mesial for posteriors, distal for anteriors). Prepping for the right insertion axis
CEREC Biogeneric gains its input from the occlusal surface and the equatorial line of the neighboring dentition. The scanning process used to acquire the information needed is based on the restoration's insertion axis as provided by the user: the software expects both planes to be perpendicular to this axis. If the preparation is shaped in a manner that an insertion axis perpendicular to the occlusion would cause undercuts, you will be forced to alter the direction of insertion. The deviation of the scanning plane from the true occlusion will negatively affect the amount of information available for the Biogeneric algorithm, potentially impacting the quality of the initial proposal. The illustration to the right should help make the situation a little clearer: (1) shows the original outline of the tooth to be restored. Perpendicular to the equatorial line (2) and especially the occlusal plane (3) will be the ideal orientation for the insertion axis (4) in order to deliver maximum data for the Biogeneric algorithm. If this ideal axis is not accounted for by the
preparation (5), undercut areas (6) may be the result. (7) shows an alternative buccal preparation slope that would optimize the insertion angle and allow for optimal results from CEREC Biogeneric.
Anterior impressions
CEREC Biogeneric changes a very important aspect of digital impressions: from now on, always scan from occlusal/incisal. Even anterior
impressions for veneers, taken buccally up until now, should be taken from incisal. One workflow means one impression method!
Imaging for buccal bite registration
When taking buccal shots, there are a couple of simple tips which should help achieve perfect results:
One image is usually enough. If desired, a second or third shot may help orientation during the
registration step – for example by including the gingival ridge on the preparation and
antagonist. Additional images have no negative effect on accuracy.
Your images should be approximately centered – one half composed of the prep side, with the
antagonist taking up the other half.
Whenever possible, it's best not to include too much "empty space" in the buccal image. On
crown preparations for example, try to take the buccal image from the neighboring teeth rather
than including the oral cavity.
Artifacts from such images are filtered out quite well, but images from intact teeth are better.
Correlation
With CEREC Biogeneric,
correlation has become an even
more powerful tool. By
manipulating the copy line, the
user can choose which areas of
the original tooth to copy.
Everything outside the copy line
is re-created by Biogeneric. This
makes correlation the perfect
tool for restoring existing
dentition, as shown in the
following example. Record the
original situation in the field
"Occlusion". Don't forget to
save, then prepare the tooth and
record the preparation before
continuing. Once the model has
been reconstructed, select
"Window", "Display options"
from the menu. In the dialog
"Display Options", activate the
selection "Occlusion" in the
column "transp.". This displays a
semi-transparent view of the
original dentition (which you recorded in the "occlusion" field) superimposed over the preparation, which allows you to double-check the
stitching results. After the preparation margin has been marked, the copy line will be displayed on the original tooth. Everything within this line
will be copied 1:1 for the restoration. Areas outside the line will be recreated by Biogeneric. Edit the copy line as needed - for example to omit a
fractured cusp which you wish to replace via Biogeneric. Once the restoration results are displayed, they can be easily compared with the
original situation and edited if needed.
Replication
If you would like to use a different tooth than the default source (see "Providing input information") as an information source for CEREC
Biogeneric, Replication is the perfect tool. Record the desired source tooth (e.g. a non-default neighbor, contralateral, antagonist, even a model
tooth) in the "occlusion" window before continuing. Once the insertion axis is set, the dialog "Select Tooth Number" will appear. Select the
position of the source tooth, and mark its center with a red dot (double click) in the screen that follows. Make sure to set the dot on the incisal
edge with anteriors. CEREC Biogeneric will then use the tooth set as an information source.
Summary
CEREC Biogeneric makes your daily work easier. No matter what type of restoration you are working with, no matter which method: the
workflow is always the same:
Acquire, (with custom source in "Occlusion" window if desired), optional trim, prep margin, insertion axis, (Modify custom source if recorded),
done.

When you upgrade to inLab 3D Software V3.80, you’ll likewise benefit from the new
Biogeneric design modes for inlays, onlays, crowns and full anatomical bridges. In
addition, you can select a preferred morphology – for example, for edentulous jaws and in
cases where a suitable reference tooth is not available. Thanks to the new “Multilayer”
design mode, you are now in a position to produce anatomically sized bridges exclusively
with the aid of CAD/CAM technology. The bridge design is automatically separated into
two components: the framework and the veneer structure. Allowance is made for the
minimum wall thicknesses of the materials. The components fit together perfectly (i.e.
without undercuts) after milling and sintering have been carried out.
The abutment design functions have now been fully integrated into the software. New
titanium bases have been added.
6. Market launch of CEREC Connect in Europe
Following last year’s market launch in the USA and Germany, the CEREC
Connect portals went online in the Netherlands, Austria, Switzerland and the
United Kingdom in June 2010. CEREC AC users and inLab laboratories can
now register and reap the benefits of digital impressions. France and Italy will
follow in September 2010 and October 2010 respectively.
A new English-language portal has been created for the United Kingdom. The
portal is available in German to Austrian and Swiss users. Dentists and
dental technicians based in the Netherlands can choose between German
and English.
The workflow is identical in each case. The dentist takes a digital impression
with the aid of the CEREC Connect software, evaluates the resultant model
and marks the preparation margin (optional). Following this the dentist sends
the data to a preferred partner laboratory from his country. With the help of
the inLab software the laboratory downloads the data in just a few minutes
and evaluates the model. Thanks to the high data transmission speeds, the
laboratory can contact the dentist before the patient leaves the practice in
order to discuss any necessary changes.
On the basis of the data supplied by the dentist the laboratory orders a stereo-lithography (SLA) model from infiniDent our central production
facility in Bensheim, Germany. Parallel to this the laboratory can design the restoration ready for milling on the inLab or inLab MC XL unit and sintering (zirconium oxide). As soon as the model has been delivered the restoration can be completed and dispatched. Three-unit bridges now available via CEREC Connect Since 1st of April 2010 dentists and laboratories have had the option of ordering three-unit bridges via CEREC Connect. This significantly extends the spectrum of possible indications. As a result CEREC Connect is a very interesting proposition for CEREC AC users who have their own in-house milling machines. As is already the case with single-tooth restorations the user creates a digital impression using the CEREC AC. After the impression has been checked it is transmitted to the partner laboratory via the CEREC Connect portal. The dentist indicates the required restoration type (full bridge or bridge framework) in the order form and marks the corresponding teeth in the dentition diagram. The program icons are identical to those used for temporary bridges. The laboratory then orders an SLA model in the usual way. The restoration is then created on the basis of this model. Dentists who own a CEREC milling machine have the option of importing the data into the CEREC 3D software, prior to designing and milling a
bridge out of a provisional polymer material. In this way it is possible to create restorations with up to three units without the need for any
conventional impressions.

7. New marketing materials Patient marketing

We have developed new marketing materials designed to inform patients about the CEREC
procedure. A new flyer and appointment cards (claim: “Beautiful teeth with CEREC”) are available
via your dental equipment dealer. You can also order practice posters featuring the same design.
The patient flyer “Beautiful teeth with CEREC” informs patients about the benefits of the CEREC
procedure, describes the various therapy steps and emphasizes the outstanding longevity of the
CEREC restorations. Printed in the handy format (21x10.2 cm), the patient flyer is available in
packs of 100 from your dealer.
The appointment cards “Beautiful teeth with CEREC” are an effective way to advertise your
CEREC treatment services. Printed on high-quality heavyweight paper and measuring 10x7 cm,
the cards are available via your dental equipment dealer.
A digital version of the practice poster is available free of charge from your dental equipment
dealer.

What You Can Do to Prevent Dry Socket

What You Can Do to Prevent Dry Socket

Many people take good care of their teeth but for whatever reason may have to have a tooth pulled. While many people just experience discomfort for a brief period following this procedure there are times when it does not go away. If this happens it is likely something called dry socket has occurred.

What is dry socket?

The hole in the bone that a tooth sits in is known as a socket. When a tooth is pulled the socket becomes open.vThe natural response of the body is to create a blood clot so that tissue can eventually grow over and protect that area that once housed the tooth. However, on some occasions the clot does not form or dislodges. This exposes the underlying nerves, tissue, and bone to the environment of your mouth (air, food, water, etc.) and can cause intense pain and even infection.

Dry socket can be identified by its appearance (a dry socket instead of a healthy blood clot where the tooth was pulled from) and its characteristic pain which can at times radiate into the ear. Sometime this happens by chance but dry socket occurs more frequently in individuals who smoke, have poor oral health, use birth control, or have a tooth pulled because it is wisdom tooth. Naturally, one way of reducing your likelihood of getting dry socket is by refraining from smoking and taking better care of your mouth.

What you can do if you get dry socket

If you have dry socket there are few ways you can treat it.

The most common way is over the counter NSAIDs such as aspirin and just wait it out.

Another thing that is advisable is to see your dentist. This will ensure there isn’t an infection and if there is they can give you antibiotics, clean the socket, and place medicine in the socket to promote healing and keep it clean.

Dry socket isn’t considered very common, but is by no means rare and does occur. If you have a tooth pulled and pain begins a few days after the procedure examine your mouth and consult a dentist.

Causes and Remedies for Bad Breath

Posted by Ronald Wagner on Dec 20, 2011 in Blog | Comments Off

 

Bad BreathTaking care of ourselves is one of the most important things that we can do. While we may not realize it, we still fall short or become lazy in some areas that concern it. One of these areas is our mouths. Many of us take pretty good care of our teeth by brushing them every day, but fail to take care of the rest of our mouths. As a result it can manifest itself as bad breath (known as halitosis). Bad breath isn’t just caused by eating too much garlic at lunch or forgetting to use some mouthwash before heading out; it can be a sign of fundamental errors in the way we take care of our mouths.

Causes and Remedies

1. One obvious cause of bad breath is simply: food. The things that we eat leave remains in our mouths and can smell poor. Onions and garlic come to mind for most people. The reason that these smell so strong is that the enzymes in our mouths can’t break down the aromatic compounds and so the stinky garlic or onion smell persists until you swallow all of the remaining chemicals. An easy remedy for this is brushing your teeth and rinsing very well or simply not eating these foods at all. For simple bad breath not caused by food (maybe you haven’t brushed your teeth in a few hours) try a glass of water or a slice of bread.

2. Other causes of bad breath can be a little more serious. Many people brush their teeth but neglect to floss. By not flossing you do not clean the spaces between your teeth as well as your gums. These areas act just like your teeth and contain bacteria and plaque that needs to be removed. Flossing will remove this and can help reduce bad breath. Your tongue falls into this category as well. Brushing your tongue or using a tongue scraper will help keep it clean and reduce bad breath.

3. Another cause of bad breath is oral infection or colonization by harmful bacteria, especially on our tonsils or other areas of our mouths. If you brush your teeth, floss, use mouthwash, and don’t eat stinky foods and still seem to have poor breath it is imperative you see a dentist or doctor immediately as this can be a sign of a serious condition.

Being aware of what causes bad breath can help you prevent it. Many people over react to their breath because they perceive that others can sense it as much as they can, but in reality many people can’t even notice. Chew a piece of sugarless cinnamon gum after meals or brush your teeth, keep your tongue clean, and use a healthy mouthwash and general bad breath (halitosis) should easily be avoided.

Tips for Preventing Cavities

Posted by Ronald Wagner on Sept 28, 2011 

Protecting your teeth has become easier than ever with today’s advanced technologies in both the medical and dental field. Science has cracked the code and discovered the many secrets to protecting your smile. One of the easiest and most effective ways to keep your teeth healthy is preventing cavities.

Tips for Preventing Cavities

Brush Your Teeth

One of the easiest ways to prevent cavities is very obvious; brush your teeth. It’s not always possible to brush your teeth after meals, but when you can you should always take time out of your day to do this. You can also contact your dentist and request information about ways to clean your teeth after meals when you are unable to brush.

Eating Healthy

Eating different foods is also a great way to prevent your teeth from getting cavities. Many people think that it is just sugary foods like candy that give us cavities. This isn’t entirely true. While sugary foods play their role it is actually foods that have sticky carbohydrates like chips, breads, and other grains. The way this works is that those foods stick inside your mouth (much easier than the simple sugars in candy) and the microscopic bacteria feed on them. The bacteria, having been fed by the small particles of food that won’t readily leave your mouth, then cause cavities and damage your teeth. It is for this reason why brushing after meals is double important; to remove not only excess bacteria, but the sticky carbohydrates as well.

Floss Your Teeth

Flossing is another great way to protect your teeth and not to mention your gums. If your gums become unhealthy, your teeth will rot so taking care of both of them is essential for overall mouth health. Brushing can miss the areas between your teeth and flossing will help remove what brushing misses. In conjunction with this, talking with your dentist about potential oral rinses or mouth washes may be beneficial as well.

Cut out Acidic Drinks

Cut down on consuming sodas and juices. Soda and juice tend to be very acidic. This high acidity level can wear down the enamel (a protective layer on our teeth) making the teeth weaker and more susceptible to decay. By replacing your beverages with things less acidic like water you can reduce the damage on your teeth. If you simply can’t live without your morning orange juice or your soda at lunch then you can help reduce the acid’s damage by drinking through a straw. Using a straw will help diminish the amount of liquid that comes in contact with your teeth, however this is not as effective as not drinking the drink at all.

Make Regular Dentist Visits

Last but not least seeing your dentist and getting regular cleanings in one of the best tips for preventing cavities. Oral problems in general develop over time and have many, but small warning signs. By seeing a professional regularly you can prevent these problems from developing. A dentist can also advise you in new ways to prevent cavities and ultimately keep your teeth healthy.
