THE MOST COMMON question I get asked is "what should an onlay prep look like" To understand the design we have to take a step back and look at Biomechanics and Biomimetics. Once we understand what Mother Nature has created, we can then come very close to replicating that when restoring damaged teeth. That…Got it, that makes sense and now I'm less worried!! I have a little kitchen digital timer in the lab so if I can time the etch. If I do a couple at a time I apply the etch to the first hit start and then keep applying. Start rinsing at 20 seconds, probably not…There is an evolution occurring in the semantics of dentistry relating to the Biomechancial functioning of teeth. A new term for the enamel compression dome of the tooth is now the Bio-dome. The tooth peripheral structure supporting the compression dome is now being described as the Bio-rim. These terms will be begin appearing…If a tooth like the one in the example can't be taken to completion, it becomes a serious restoraitive challenge! All the cusps were fractured, plus the mesio-distal and Poisson Effect fractures. I doubt there would be many undergraduates who could do a full direct composite crown with fibre reinforcing and not get post insertion…Thanks for the compliments, guys. I always hope at least one thing will resonate when I lecture and I am often surprised by what that one thing is. Wally and Tony, your work with students is nothing short of amazing! Please keep it up!I've got a full mouth rehab case ready to go and I plan to do it all with our E4D. I mounted the case and had a full wax up done. My question now is..... Can I clone this full wax up to do the case. How can it be lined up with the scanned…I think that if this is your first full mouth case on NEVO I would do the following: 1) Make temps off of the waxup you have and spend time to get them prefect with the occlusion 2) After the patient has been in temps for a couple weeks and is happy with the…Digital occlusal veneers for the patient with braces. I would buy IOS just for this kind of cases exclusevly. If you tried to take PVS impression from ortho patient once, you'll understand what I'm talking about) PlanmecaFIT + e.max HT A2, staining technique.Exactly Mike! Always have to use a veneer mode in such a cases. I told R&D guys that they could let us make a final decision. It could be just a warning message that we're out of recommended thickness. But the software just ruines your anatomy.Hi folks, This is one of my recent anterior cases. Here we replaced some old composite by e.max HT. Post-milling procedures were just staining, glazing, polishing. Who will visit IDS 2017 this week, welcome to Planmeca booth to share thoughts and opinions)This were the composite shells which I made from one of the Hajto's modelThis post is dedicated to the marginal fit of CAD/CAM crowns. Tooth #8. E.max MO1 with layering. PlanmecaFIT. https://youtu.be/WFCKjZJMGfcThis is the sort of film we see with our cad emax:Here is a veneer I scanned with the Trios 3 Scanner for your perusal.Hey Cliff, so sorry to lose part of you - the first Canadian 10 years ago for us - and yes the version of Romexis 4.4 (should be out soon) does have an "import to mill" function - so you can send .stls directly to the PlanMill 40 -but you do need to keep…Hello all here are some screen shots and a screen recording of me scanning my three year old with the Trios 3 scanner,Phenomenal! I see they use it for ears, etc. Really great to be able to offer this to our patients, especially the young! Can't wait for Systematic Digital Patient Monitoring (DPM) and then we can really practice on AutoPilot!!! Cheers CLIFFI've started offering to do some bridges for patients as a one visit procedure. I brought this physician in early before her patients started at 0630 and we finished around 945. I scanned her old bridge as a preop and tweaked the clone to improve on some areas. This is about the third one I've…I do same-day extraction and place an eMax bridge all the timeHere is a case where I prepared all the teeth in the arch but I needed my pre-op of the temps to align so we did small fiduciary marks on the tissue using XTR as the bonding agent (really stick to tissue) and some heavy flow to make the marks. Video included. [attachment=1033:DSC_6692.JPG] [attachment=1034:DSC_6696.JPG] [attachment=1035:DSC_6918.JPG]…Wouldn't be a bad idea to give you a translucent version like you get with the bite. For typical posteriors though seeing the prep isn't critical to me, mostly it's about getting the proposal lined up to the adjacent teeth properly that's the important bit.This is one of the first total rehab cases of mine. It was finished in 2009. Really agressive prep by HS handpiece, no microscope, no CADCAM. It was my practice 7 yrs ago) And there she comes in 2016 with the chipping on #6. Now I have PlanmecaFIT so we solved this problem in…Emax HT B4Great result! It seems that you already have the new version of the software. What's new? What about margins? I've heard that hey had to change algorithm and make margins much more sharper than now. Because sometimes it is very difficult to draw the finishing line even if you made really nice prep. i have…Hi guys, This is a little video review of the common posterior preps in evolution of most conservative to least. EnjoyFantastic graphics Wally!The reason I liked digital dentistry very much is easy to understand. 2 days: prep on monday evening, the same evening 2 hours at home with a glass of red wine for modelling :roll: , tuesday for milling and staining, and wednesday we finished! No lab, no headache. That's what I call "easy money". …Thanks for the case! Great result as always, Here's a tip to try next time: Alter the prep color of the incisor via an "esthetic core buildup" with dentin opacity composite. This video will show the technique and the result: https://learndigitaldentistry.com/video/veneers-correcting-for-undesirable-prep-color/ Generally, I use this method any time there is significant prep color…Hi folks, Here is the result of 90 min appointment. 1-visit dentistry concept in action :) Even if you have modern digital instruments you still need you hands to make the final restoration more artistic.Nice work! I have never used Empress. I noticed that you have a bevel on the facial and got a great color blend. What do you see as the benefit of Empress? Do you bulk the feather margin to mill, or just mill a feather edge? Thanks! Michael Hi Michael,…Orthodontist was able to erupt teeth #'s 11 and 27 but # 22 was ankylosed. Implant was not an option for # 22: Oral Surgeon was reluctant to extract this tooth because of very deficient bone in the area. We elected to cover the tooth and make an eMAX bridge. A compromise to use #…That is a tough call and a great result! Interesting "coronal amputation" of the lower third molars, too.Today my new routine case from Empress CAD Multi. #11, non-vital. [attachment=1023:planmeca30.png] We've changed huge composite to ceramics for 1 visit. It was 2 times cheaper than the lab crown on the #12 :roll: which was made a year ago. [attachment=1024:planmeca31.png] [attachment=1025:planmeca32.png]Love Empress Multi. Nice work.Just finished a 4 unit bridge 19 to 22. It fit into the bridge block. The patient has very tiny teeth. Had problems with the orientation. It would not mill until I corrected it. I keep the connection as thick as I could to maintain strength. It still looked OK and patient was happy, existing…You mentioned, "Had problems with the orientation" can you please elaborate on this. Respectfully MDS
