Baron, really appreciate your knowledge share here. You mention not using the bite relation STL at the beginning, but later have a correct bite correlation of your CR record. How does meshmixer correlate the lower and upper at the specified open bite in this video? Sorry if I missed this.
Scott Hannaman . They were aligned when they were crated via my CEREC scan. Sadly, I forgot to mention that in the video. The models need to be optically scanned or generated via CBCT at some point. In my case, I have my assistance take alginate impressions and put them up in stone and then scan them optically. Debate is taken with leakage and scans and not occlusion. Does this clear that up?
Thanks. That makes sense. I haven't played too much with Cerec/Meshmixer but use to use CDT2STL with the older Cerec version (4.2?). I'll try it out, especially with the new stl export feature (when we upgrade). I have a similar protocol currently with the leaf gauge, alginates, and my ministar machine with pressure cured acrylic added for the occlusion dial in. So essentially the bite is taken in cerec and you import that correlation into meshmixer, or the stls just correlate because of the match up export in Cerec?
Yep. The Buccal bite is taken in the appropriate bite: with the leaf gauge in if scanning intra-orally or with the bite relation material when scanning stone.
Amazing stuff and thanks for all of the work you are putting in to helping others!!!! I use planscan. Just to understand I take upper and lower scan, a bite relation in CR and meshmixer keeps them in position when I bring them over. I am baffled as to how meshmixer does it. I also have an Itero if that's any better.
Hi Baron! I’m having a persistent problem where all my prints come out looking pretty good but none of the aligners I make from them ever fit a patient!! This problem especially applies to upper retainer models. I have some pics and such but what I really need is someone to help me analyze the problem and lmk what really is going wrong. I called Sprintray customer support and they tried to do what they could but it’s just not helping. I wonder why are these models not fitting? Is there a way I can contact you for your help please?? Yours thankfully, Lisa
Hi Dr Grutter, Could you please tell me why in this case you alligned the guards at an angle with supports and not with a base plate supportless and angled at 5-10 degrees and vertical (as you're doing with the models for aligners)?
Different materials. I always print occlusal guards with supports. Models rarely with supports. Models also have flat parts to adhere to the build plate.
I now use D3 splint. This was a cool workflow that answered a need. But now, D3 splint is just so much more efficient and honestly, a much better end result. it actually tracks movement and creates functional pathways.
Have you seen this playlist? The Anterior Deprogrammer video is pretty current. Even if you want a different type of splint, it'll give you a good idea and the software will que you on what all you need to do. ru-vid.com/group/PLZ5lds9W8W8rwGk-TqGa2w_WDlIuIIyB0
Thanks for the video! I will try this way as soon as I can get my hands on that Nexdent resin. Who is your supplier for nexdent, and do you know if it works with a Form 2?
SprintRay will soon have the NextDent Ortho Clear available for order. Will it work with Form2? I believe so. However, there are no officially endorsed print profiles established for it. This means that anything you fabricate will be your responsibility to confirm complete cure for bio-compatibility.
Thanks Baron for all the great videos. I'm having a problem bringing the files into meshmixer in articulation. When I bring upper/lower models from Cerec Ortho into meshmixer they come in articulated, but when I bring in the upper with the guide and the lower, the lower is offset. What might I be doing wrong?
+Thomas Taylor try watching this video and see if it helps. For the record, the problem is that the model coordinate orientation changes when exporting from BSP. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-htsBfSuUX48.html
Not sure if it's because my software is new or what but i do not have any of those panels available under my Panels tab... any help would be very appreciated.
hEY BARON. NICE VIDEO THANKS FOR SHARING. I FOLLOWED YOUR STEPS ONE BY ONE AND I GOT THE GUARD DONE ON THE WORNG PART OF THE MODEL. IT WAS SET UP TO THE GINGVA PART AND TO THE HOLLOW PART OF THE MODEL. WHAT DID I DO WRONG? HOW CAN I CORRECT?
You either had the model upside down in BlueSkyPlan or you made a mandibular guide on the maxilla. Fix the former via Model Manipulation Panel > Manually Align Model. Fix the later by selecting Maxilla in Guide Fabrication panel.
Same Scotch pad wheel that I use to polish the edges of our clear Aligner trays. You can find links on my website.. Side note, I now use D3 splint for my splint design.
Unfortunately, getting an accurate/effective overlay in MeshMixer is extremely difficult and hardly worth the time/effort. At this point, I use D3Splint for all my Occlusal Guard designs. It's $350, but completely worth it. I have a playlist that shows just a glimpse of how powerful it is.
@@bgrutterdds I will check it out, do you need to pay an export fee with D3Splint? I make my occlusal guards without contacts or very light on the post portion, like a de -programming device with a posterior extension to prevent teeth from extruding., The patients love them. I will have to play with the software to adjust it to my technique. Thanks again for taking the time to make and share the videos with us.
Hey Baron thanks for the sharing this video. I would really appreciate if you please send me links of stl files of patient on which modelling is done. Thanking u in advance
This is awesome. Thank you for sharing!! I have a 3Shape Trios but I’m not sure how to digitally open the bite. The scanner puts them in centric occlusion. Like you said....arbitrarily opening them won’t get the correct occlusion on the guard. Ideas??
I always capture the bite in an open CR. A leaf gauge or even cotton rolls. Try to disclude the molars ~3mm. For the record, I no longer use this workflow and now use D3Splint. Just a heads up.
No affiliation. Good friend, yes. But I paid full price. D3SPLINT allows me to be much more efficient and handle much more complex cases. Also, the workflow is systematic, allowing for delegation to team members. Finally, the model processing was a bonus.
