We just purchased the Sirona InEos X5, Primescan and Primemill. Your videos have been incredibly helpful, I just had to mention that to you. (I could not hear the train.)
Do you think you will make a new video with the updated version? This video is great to help train assistants too! Just want them to see with our current software verses when we first got the cerec. Thanks!
Appreciate the Effort of making this video! By and large the Information is helpful but please be aware that the Tips on the Parameters are HARMFUL! 1. If you set the minimal thikness below the factory recommendations you are running danger of the crown cracking or splitting. Dental materials (and all materials) have a minimal thikness for good reasons. 2. If you set the margin thickness higher you automatically get a crown-margin that is overlapping the preparation-margin. hence you get a big edge where plaque will build up and cause parodontitis. Setting this parameter higher has a benefit only when you adjust the crown-margin on a pshysical model to better match the prep-margin. 3. setting the occlusal nad dynamic contact stregth anyhwere away from 0 will cause infra-/supra-occlusion. Meaning you either fitted the patient with a crown that they can effectively not use because it is too low or you will have to grind down the crown in the mouth to a proper hight. Either way you are risking to dislodge the balance of the TMJ of that patient. I encourage you to please reasses the ideas that you posted in the video and maybe even make a new one. Coming from a dentist in Germany with 10 years of practice and 2 years of Cerec-practice designing and seating my own restorations and constantly learning in the process.
I have a few questions as well... 1. Who says the doc isn’t refining the margins after the crown is milled? The MCXL has limitations... the marginal thickness is set at that level to prevent chipping during the mill process. 2. Do you ever exceed the manufacture’s RECOMMENDED thickness? That would require either very aggressive preparations or we’d all be walking around with crowns that look like inflated marshmallows. It’s a recommendation, not one of the 10 commandments. I have not nor have any of my clients experienced any issues because of setting the minimal thickness at 500 and if you listen to what I teach in the video... setting the minimal thickness to 500 doesn’t mean your crown will be that thickness, it means if you see the bubble you’ve exceed .5mm of thickness which I agree... would not be good. 3. I’m not recommending to take the crown WAY out of occlusion… I’m recommending negative -50 microns I think it was... when your milling a hard glass ceramic such as e.max the mill does what I call bur ricochet… Meaning you end up with a highly inaccurate mill, that’s also what the milling offset is for. We set the occlusal strength to negative so those milling inaccuracies don’t cause high occlusion.
Hey Weston thanks again for these tutorials. Just wanted to know if you know how to add more implants systems to the inLab database for use with intra oral markers.
I have a question, I scan on a omnicam, will these techniques work on that scanner/ software as well? I'm new to all of this and not sure what im doing.....
Great video Weston! Any tips on adding to the MB of this crown near the margin in order to close the interproximal space and help avoid food entrapment? I currently use the circular tool but I find that when I pull it out, it doesn't pull out at the margin very well and it creates a weird concavity by the margin. Hope this makes sense. A little hard to explain it in words. Thanks again for such an informative video!
Marginal placement will determine how much you can manipulate. If you have a supragingival margin you will not be able to fill in that area... however when it’s cutting it close the best tool to use may be the “add form” tool... allows a little more freedom than the circular tool. Hope this helps!
This video is a lifesaver for a new user like me who only had one day of instruction. Thank you so much!
SAME!!!!!!
3rd year dental student here. Great video! Thanks!
Excellent Weston!
Fourth year dental student here, a few months away from working in an office with CEREC. This whole video is super helpful!
Thanks so much Weston! Great video
Amazing video. Best one. Very very helpful.
awesome tips! Thank you! 🎉
Awesome information and tips Weston!
Very informative video Weston..just about to start milling my crowns so Im sure I'll need all of it. Thanks

Thank you for the information!! It was very helpful.
Thanks for the valuable knowledge
Great Video!!! Will share it with my co-residents. What are the set parameters for a Katana Zirconia crown and a Celtra Duo crown?
Do you think you will make a new video with the updated version? This video is great to help train assistants too! Just want them to see with our current software verses when we first got the cerec. Thanks!
Great video! Thank you for all the tips.
Excellent video! Cheers mate thank you very much!
Loved the video, lots of great info, thanks for sharing!

Very very very nice and easy and useful vedio thaaaaaaaaaaaank you very much thank more than you imagine 🙏🏻🙏🏻🙏🏻
Thanks for the information is great!!!!
Weston, any helpful tips for premolars? Specifically for "crownlays." Most of my premolar crownlays look like spaceships. IE they are just bulging!
Reduce minimal thickness... use the biogeneric variation tool.
Do you have a video for the gingival mask process?
Hey Weston thanks again for these tutorials. Just wanted to know if you know how to add more implants systems to the inLab database for use with intra oral markers.
No way to add unless you download a foreign version of the software (not US)... then you get a few more systems that aren’t available in US.
I have a question, I scan on a omnicam, will these techniques work on that scanner/ software as well? I'm new to all of this and not sure what im doing.....

Do all the settings you changed in the parameter area also apply to zirconia crowns? Since i did notice you were making an emax. Thank you!!!
What setting do you use for occlusal offset? and Adhesive gap? Great video, really helped me with my design!
Creating restorations - crowns that are “slightly out of occlusion” is a terrible, you ruin peoples bite, it would collapse!
