We CEREC owners are 11000 strong now. Slowly becoming more and more mainstream as regular average joe dentists are finding the value of one visit dentistry. As more clinicians realize the benefits of same appointment dentistry, without messy impressions, goo, temps and all the other inconveniences of the traditional way of restoring teeth, the obvious beneficiaries are our patients. I cant tell you the number of referrals we get from happy patients who would never go back to the old way of temporaries and a second visit. How great would it be to spread the word beyond our patients? With our numbers, we might be at a tipping point. We might be at a point where we may have enough CEREC owners who if they join together can really make a mark on the consumers. The ADA hasnt done it. Sirona hasnt done it. Patterson hasnt done it. Maybe we have enough members for us to do it, to do a marketing campaign similar to the Lumineers campaign done by Denmat. If we can find a way to get consumers educated on the CEREC process, how beneficial would that be to CEREC owners? To dentistry in general? What do you think? Let us know your thoughts on the matter. Would a national marketing campaign be worth it? I dont know but Id love to get your thoughts on it. Join the discussion on this thread and let us know if this is a good idea or not. http://www.cerecdoctors.com/ui/ViewForumNew.aspx?ForumID=2976 Its a thread titled 'Im surprised this hasnt been done before'

The original CEREC 3D with the red cam and compact mill was and still is a fantastic system. The key to sucess with that system was of course the 3 P's. Prep, powder and PICTURE. I capitalize picture because I always felt that it was the most important part of the three. It was necessary to take a properly aligned, non pitched or yawed image of your prep, that showed your entire margin. For each restoration, one image was great, two was OK, three was pushing the limit and over that you may have been doomed by image averaging. Averaging occurs when, because of camera angulation, a lack of powder or blood and saliva creeping onto a margin, two or more images of the same area appeared to the software to be slightly different. An average of that data, right or wrong was the result and we built our restorations to that averaged area. On the whole we still ended up with an exceptional product. Once in a great while we had a short margin or a tight fit or an open contact and we couldn't figure out why. Along comes the CEREC AC with the blue cam and we now find ourselves needing to unlearn some things and relearn others. First, extra images are not necessarily a bad thing. As long as they are good images we can take a few extra and not worry about averaging. Most importantly, we can build larger models and not be appreciably slowed down because our systems have an abundance of power and improved graphics capabilities. So what does this mean for us clinically? Well, right now we have faster transitions when we green arrow. Nicer looking virtual models with less powder needed, margins that are easily discernable and that pop out at us when we marginate and finally, larger models which allow us to tweak our proposals with greater accuracy. In the future, we can only imagine the possibilities. Proposals that can be based more upon information obtained from our larger models which show more of the adjacent teeth. Right now, inlays and onlays are built from information given by the remaining cusps and inclines. Crowns don't have remaining cusps so it only makes sense that this information will be gotten from adjacent teeth. Larger models may give way to easier quadrent work with simultaneous design capabilities. We can do it now with temporary bridges, why not with with multiple, single tooth restorations? The forward thinking of Sirona's software designers does not always make sense to us in the present. One thing needs to be introduced, become perfected and proficient in, before the next can be introduced. Thankfully, we just do our day to day work, changing and adapting as we go. We can let them worry about the logistics. We are all part of a plan that is gaining strength and momentum and will beneft us greatly as practitioners in the future. Enjoy the ride!!

Its amazing what this website has evolved into. What started out as a way to share information and a few videos that were made by putting a camera on our CEREC machines has grown into thousands of members from all over the world. Some of the new features we have added is the ability to put videos directly into the discussion thread. Now when someone comes and asks a question about parameters, margins, etc, we can simply link the appropriate video right then and there. The next phase will include all flash videos and other features which will make the user experience better for all users. Starting in January, both Sirona and Patterson have committed dedicated members from their support team to monitor the message boards so that technical questions that the faculty cannot answer can be addressed from the corporate level. What I am most proud of is our dedicated faculty who tirelessly help out all users on the site. Armen and I used to spend hours providing support and now before we have a chance to address the users on the message board, the questions have already been answered by skramy, gardell, caso and rosenblatt. Couldnt ask for a better group of guys to work with. All in all, over the past few years, we have had some growing pains no doubt - thousands of owners a year, you are bound to have some issues. However as we move forward and Sirona continues to innovate our little CEREC machine with software updates, we hope that you make cerecdoctors your home for all things CEREC.

I just finished my first restoration after installing the 3.65 service pack. It was a full coverage emax restoration on a second molar. I prepped a high lingual margin and the tooth leaned mesially a bit. The type of prep was notorious for an open buccal margin and a slight rock with the previous software version. Not so today! The crown dropped in with the best margins ever and a solid, non rocking fit. The combination of this software upgrade and the blue cam made this restoration very simple. The mesial inclination of the tooth sometimes would lead to a light or open margin mesially due to imaging problems. It is hard to get the margin imaged as well as the distal surface of the anterior tooth. In the past it was difficult to build the contact to good or real data. The blue cam has solved this issue with ease. Finally, being able to use emax in this area is really amazing and something we should really be happy about. I will have no concerns about this restoration long term because of the great fit and the strength of emax. Recent research has been so positive regarding emax that we should all feel totally confident using it in any application. With such positive changes to hardware, software and materials, restorative challenges are overcome so easily. Today's experience was a prime example of what is possible when everything comes together so well. We make it look so easy that many times our patients just don't have any idea about the massive behind the scenes efforts that make this happen routinely. So, the take home message is, install the 3.65 service pack right away and enjoy its many benefits on your next case. Jeff

Awesome Buccal bite is so cool. Its been great using this with cases. I Did my first cerecconnect case posterior bridge imaging went well. I do see some areas that need improvement but all in all I think with a little bit of practice, it will be a great improvement to our workflow when restoring cases with Connect. Im looking forward to having it come in the regular software whenever Sirona implements it into the regular software. A couple of tips I noticed that made my buccal bite process a bit easier. I found that if you have an area in the prep in both prep and antagonist where you roll the camera enough to capture landmarks for stitching. The first time I did it, I had to go back to get some more images after I couldn't get the bite to 'snap' into place. I do think that with a bit more practice, this will be second nature as with anything in CEREC dentistry. I know other faculty have been testing buccal bite for a while and they have found it very easy to stitch. All in all I think its a great improvement to our software and it reinforces my decision to go with Sirona and CEREC as my cad cam of choice. Im looking forward to what else will be in the new software release in the coming months as the guys in bensheim burn the midnight oil.

Please see this discussion forum post for an important patch to Cerec Software Version 3.6. This is something you definitely want to download. Takes care of some very importants bugs in the software: http://www.cerecdoctors.com/ui/ViewforumNew.aspx?ForumID=2930

Anyone start doing cerec-connect yet? I love it. cases have been great. I, like others, have questioned connecting my machine to the evil internet (even though it is probably fine). Here is a 'how to' for those that want to export a connect file to another computer. Just make sure you have cerec connect on your machine. for those that don't yet, go to cerec-connect.com and click on dentist registration. 1) downoad cerec-connect onto the computer you want to send the case from. You will need the cerec connect disc 2) image the case on the machine, make sure it stitches, and draw all margins on the machine. I find that to be easier. Then save it 3) put a thumbdrive into the cerec machine and open it so you can drag the file in later 4) go to my computer>c: drive>program files>CEREC>DATA>and locate the case you just saved and click on that folder 5) There will be 2 files in here. Drag the file named 'restauration.cdt' into the thumbdrive that you opened earlier 6) You can rename the file on the thumbdrive by right clicking and hitting rename 7) Remove the thumbdrive and plug it into the computer you installed connect on 8) open the thumbdrive and find the file you dragged in there. Drag that onto the cerec connect icon and the program will open and you are ready to start filling out your digital RX form Mike Skramstad just uploaded a bunch of videos on CEREC Connect and Buccal Bite: Introducing Cerec Connect Introduction Videos and Buccal Bite By Mike Skramstad (Adjunct Faculty) Wed Nov 04, 2009 11:05 AM Just wanted to notify everyone that a new section of Cerec Connect videos has been uploaded. These videos will cover the folllowing: 1. Introduction to the Cerec Connect process 2. How to sign up for Cerec Connect 3. How to use the Cerec Connect Portal 4. Bridge case start to finish with Cerec Connect (very detailed) 5. Introduction to buccal bite 6. Full arch articulation using buccal bite. Some of you may be asking, 'what is buccal bite'. This is a brand new feature just introduces last week at the Cerec Symposium. Basically, it allows us to articulate upper and lower arch digital impressions without using bite registration material. Simply have the patient close in centric occlusion and take an image from the straight buccal. This truly is a game changer and one of the best new features in the CEREC software introduced in quite some time. I'm excited for you to watch the videos. Mike

Sitting back cooking an Emax staight forward boring in fact Database # 14. Just told the small filling that was to be during the cook time cancelled. Kid sick Blah Blah Blah... The saving grace of Cerec is I can do that implant restoration that is sitting on my counter. Already have the implant level impression done so time sitting on my butt has turned into productive time. Get the patient in the book for the delivery. Pete
