This was my first 6 unit case with PrimeScan. From the time the patient was seated until he walked out the door, this case took 4 hours with one mill. Between the faster imaging, the 5 click process and faster proposals, this is a noticeable difference in time for me.
This patient is in sales and has always wanted a better smile. We did the upper 6 last year and he like them so much he wanted to do the lower as well. This case is a perfect case to open his VDO but he has implants in all 4 quads and wasn't ready for that kind of financial commitment so we discussed what was realistic as far as how big the teeth would look and went for it.
A couple of things I wanted to share with this case...
One of my favorite things I do when I work with anteriors is to design in BioIndividual but add a BioCopy folder for reference.
This comes in handy to know where your midline is and how much you want to increase your incisal length if you have the room. The software program does not use this folder for proposals and you don't have to draw the copy line (which speeds up the case). It is purely for reference if you select the BioIndividual in Administration.
To turn on the BioCopy you click on Display Objects and then click on Lower BioCopy. Depending on which folder has the larger teeth you then use the slider bar to make the larger teeth more transparent so you can see the difference between the proposals and the original teeth. If the proposals are the larger teeth, make sure you group the teeth together so that they will all turn transparent or you will only be able to see one at a time.
My second recent find is an Ivoclar product called Cervitec Plus. It is a Chlorhexidine varnish that does not stain or taste. You dry the teeth and tissue and place it with a microbrush. It helps with sensitivity and tissue healing and I have absolutely fallen in love with this product. Here is a picture at seat date and one less than a week later. This patient has gingival hyperplasia from meds and his tissue is always a mess. I was so shocked at how fast he healed. My hygiene team has been using it a lot for perio as well and have loved the results at recall.
Implant crowns are by far my biggest ROI when using my CEREC and I love not only how simple the process can be but how gorgeous they are. I schedule my patients for two, 30 min appointments and often they are out the door before that. My assistants do the initial scanning, the initial design, and then I check it and make sure I like the emergence profile and push mill (this way I can say I made it ;). My assistant places the crown on the Tibase and we get the patient in within a few days at the most. My personal time with the patient is typically about 10 min unless there is a hiccup. It's amazing.
We have really been trying to focus on just taking a few minutes to contour and characterize all of our restorations instead of racing from the mill to the oven. It's so much fun for my team to see what they are capable of doing and it really does just take a few extra minutes.
If you are not doing implant restorations, do yourself and your patients a favor and take level 3! You will love the results!!
I was organizing some case photos and ran across these pics.
The first set of veneers were done back in 2007 with the Redcam using Vita Mark II blocks. The new veneers were done in 2016 with the Omnicam using Vita Triluxe blocks and I added staining at the incisal edge to give it the halo effect. I love to to characterize but sometimes there is beauty in the simplicity.
I did not redo these veneers because they were failing. I redid them because my skills improved and I knew I could do better. This is my charside assistant who I stare at every day and I was so happy she let me redo them. She shows them off to patients all of the time when they are nervous about getting restorations done in the anterior. She is one of my best marketers!
Going on 13 years of being a CEREC user and I still learn tips daily on how to make my restorations better and increase my skills as a practitioner. I love what we get to do every day!
I don't normally work on Fridays but will come in for big cases. Today I was coming in to do a hybrid case with the periodontist in my building and as I was getting ready I got a panicked voicemail from a patient that she broke her veneer on her front tooth ("you know the one you were telling me that I would need to fix?"). No one wants to go through the day, let alone the weekend, with a broken tooth so I told her I would meet her in the office.
She did a great job at busting off half of her veneer on #8 and you can see the decay at the margins of #8 and #9. She also had this funny composite on #7 and didn't like the lingual tilt of #10 so she asked if there was anyway we could fix them all today... Sure! I felt like crowns on #8 and #9 were more appropriate given her bite and did more like an aggressive veneer on #7 and #10 because I didn't want her to break those. She wears a night guard but obviously has some grinding habits.
So we got her all fixed up with 4 restorations. I chose to do e.max BL3 HT mainly because it is what I had available in my drawer. I think Vita would have been a great block choice here too, but I do like how the e.max turned out. I used white stain to give the halo effect and small decal marks and then I mixed the I1 and I2 translucent stains for the translucency just to give it a bit more pop. This is a same day seat photo and I can't wait to see what it looks like with the tissue healed all the way.
Everyday I get to use my CEREC I am a little in awe of what we can do in our practices. This case took me 4.5 hours from her being seated to her walking out the door. The new updates with 4.6 have definitely sped up my design process with the new 5-click features. She knew she was going to have to sit for a bit but was ok with that because we were taking care of her last minute and she didn't want to go without teeth.
Now I get to deliver a hybrid conversion and change another smile. Today is a really good Friday!!!
This summer I had the opportunity to go to a women in leadership meeting held by Dentsply Sirona where I met some amazing and talented women. I have been working hard to get them to post their cases but it has been a little intimidating for them due to some previous experiences so I asked if I could share a few of the cases that get sent my way. It is intimidating to share work that you created yourself because you have to own it and often we pour our heart into our work. This is the only way though as a community we can elevate ourselves and other clinicians by sharing our work, encouraging other,s and offering constructive criticism when needed. It has been disheartening to see some of the bashing that happens online on some of the Facebook groups and that is why I am so proud of the community that we have all created with cerecdoctors.com.
Look at this work!!! I was blown away. Just to be clear- These are not my cases. I would be so proud to show them as my own, but I get no credit for this talent.
Case 1- e.max crowns #26 & 27
Case 2- Empress veneer #8
Let's show these talented doctors that posting your cases doesn't have to be scary. Show your support, and if you have feedback they are hungry for it, but just be kind in how you present it please ;)
I love to use Maryland bridges as long term temporary solutions. Especially when kids are getting out of ortho and not quite ready for implants. The most difficult part is typically the connector for these types of cases. A great tip I just got at CERECdoctors.com to help with this is to design the Maryland Bridge with the connector as an intersection, get the connector to about a 3, and then go back to admin phase and switch it to anatomic. This will help bump up the connector automatically to the needed size without the ridges that anatomic normally gives (I believe it is called the Fleming technique ;)). It was a great tip that helped speed up design. That is just one more reason why I love this group. Even coming to the courses to mentor, we can always get great tips!
Here are a few examples of some fun Maryland Bridge cases with kiddos. These can be done with the wing on the facial or the lingual and there are examples of both. This is dependant on the bite. What material I use is dependant on the amount of time and the amount of characterization that is needed. If the restoration needs to last less than a year, and I don't need to prep anything, then I love using GC Cerasmart. If the restoration needs to last several years, I have personally found that e.max tends to last longer. I do warn my patients and parents that these can fall off. It doesn't happen very often, but when it does it is only at the most in-opportune times. The good news, it's very easy to recement it and typically there is no damage done. They still love this solution much more than a flipper.
1. This is an interdisciplinary case with my orthodontist and periodontist. Her centrals were hopeless due to trauma but placing two implants next to each other can be really difficult to restore. We extracted #9, moved #10 into the #9 space and are holding on to #8 as long as we can until she is ready for implants (hopefully). She is 15 yrs old at this point.
2. Post ortho, a young man missing #9 due to trauma. He is 16yr old and still growing and could not stand having a flipper.
3. A young man congenitally missing #10 and also too young for an implant.
I decided to mill this instead of building it up by hand for this young woman. It milled in 6 min and then I added color tints and a thin layer of microfill of the top to seal in the color tints.
This was one of those cases that was just fun for me to do ;) I might have gone a little intense with my translucency stain but overall I think it blended pretty well. She was really excited to not have the dark tooth anymore. Just something a little different!
I don't get to do a lot of bleach shade cases in my neck of the woods so I am always a little surprised when I actually get the chance. Whew! They are bright and they are white!
Here is a woman who wanted some new crowns due to recurrent decay and she felt they were too yellow. My camera does not do the existing crowns justice. They were a B1!
Her concerns with her previous crowns:
1. #9 was longer than #8.
2. The incisal embrasures between the laterals and centrals were too open.
3. She also didn't like the "black pepper" look between her centrals. #8 and 9 had previous endo.
4. Her crowns were too yellow and she wanted to match her "new crowns" on upper right.
5. Her crowns were all different opacities- #8 & 9 were lava crowns, where as the others were e.max done at different times.
Her plan is replace her lower anteriors next year as well as her upper left crowns.
Here is what I love about my CEREC. This case was pretty easy because all of the hard work was already done for me. I could have done this either Biocopy or Biogeneric Individual. Personally, I chose Biogeneric Individual purely because doing the copy line is an extra step and takes more time. I do however add the Biogcopy folder in the acquisition stage, and scan the existing crowns so that I can use this as a reference point for midline and incisal length. I also have my checklist of things she didn't like and can correct that by ghosting the Biocopy model over my proposals. She did not want a lot of characterization in this case as far as staining, because she wanted Hollywood white. My rule of thumb on this is, the less staining the more contouring. It's how I can get them to pop.
This is a case I chose to do same day. Why? Because seeing one patient vs. 15 is very calming to me personally, and also because when I leave my office, I don't have time to come back and do lab work. The one visit is my scheduled lab time. This is also how I market my practice and I am comfortable with that. My husband does cases like this in two visits because for him sitting with one patient is the exact opposite of calm. He would much rather do this on his own time with no pressure of time. Is there a right way? Yes, of course- It is always the wife's way!!! (just kidding- the right way is whatever you are comfortable with!)
The new crowns are e.max BL 2 MT crowns. I needed a touch of opacity to block out the RCT on #8 and #9.
Late night CERECing thoughts...
It's very humbling to look back on cases when I started using CEREC 12 years ago. I was so happy to take a crown straight out of the mill and put it in the patients mouth. I had no idea what I was looking for when I looked at a tooth, other than if the color was right (which really meant was it close but not perfect). Today, I look at teeth in an entirely different way. I love to see the color patterns, the anatomy, the contouring and the light reflections. I am able to see this now because I posted cases and other doctors were willing to show me how to improve. I was also willing to accept those answers. That is what I love about this forum. We are all here to grow.
So what do I see in a case like this...
Anatomy of a youthful tooth: sharp line angles, prominent central lobe and contouring at the gingival embrasures on the mesial and distal. This is contouring that is done post mill.
Fun color patterns: the white bands at the gingival 1/3, the blue translucency and the white framing along the incisal edge.
Reflections: Do my reflections mirror each other? If so, then my anatomy is similar. If not, I need to re-contour to get them to match.
and the final...
Don't you just love that we have this capability in our office? So.dang.cool.
Here is a woman that came in with an old PFM that had recurrent decay but she was nervous to replace it because she didn't want the new one to "stick out". These are the cases I love!!
One tip that I like to do is mix my stains to get the color I want to achieve. This is a great example of that. She is pretty bright overall with a lot of translucency. Normally when I use brighter shades like B1 I would use "I 1" (the blue stain) to mimic the translucency, but in her case blue was just too bright- so I mixed it with the "I 2" (the grey stain) to tone it down but still give it some richness in color. I did the same thing for the body stain as well. The "1" stain (A range) was just a little too strong, so I mixed it with "creme" to tone it down. This only takes a few extra seconds but it gives you a huge palate of colors if you are willing to mix them.
The second tip that I have learned from others on this site is to look at the case from different exposures. I just wanted to show that in this example with the two different pictures- immediate seat and follow up. Looking at the different exposures can really help see the color in the tooth in more distinction. To do this with my twin flash, I take one picture with my flashes all the way tilted back and take a second photo with my flashes all the way tilted forward. Some of this will depend on the light in the room as well, but this is just a fast way for me to look at the teeth in different light. You can also do this on a lot of apps- like the photo app on your iphone.
What do I do when I am done with these cases? I look at my photos and see what I would have done to change it. I do this with my assistant, never in front of a patient. This is how we all learn to be better and hopefully improve with each case. Posting cases are also a great way for all of us to improve. That is the value of cerecdoctors!
Here is what I would have done differently:
I would have added either a little bit of glaze to the mesial incisal corner to sharpen it, or contoured #8 to match. This is an area that drives me nuts. If you use the smooth tool at all in the area it will round the mesial incisal edge and this is what you will get. I try to over close this area prior to mill just for this reason, but I got a little carried away here in my contouring.
I would have used "creme" for the craze lines instead of white. In the mouth this doesn't show up as dramatic but my camera never lies. Using creme would have been more subtle and matched her other teeth better.
One tip that I picked up from some cases here on the boards- add the body stain at the incisal edge of worn looking teeth. Often if you look at anterior teeth there is a lot of color right at the incisal edge- dentin showing through with the wear. I love to add a little of the same color I used at the gingival 1/3 here to mimick the other teeth.
What was cool about this case- The patient was in my chair for 2 hours and left with a new crown that she loved. That is the power of CEREC that we have available to us every day.
