1. What about cusp ridges and bevels ,are they the same as conventional crown preps? 2. Are external walls divergent or parallel ? 3. at 36:29 why didn't we build up that proximal wall to improve stability and retention. I'd love to watch a webinar about direct cuspal coverage Thank you so much.
Neat work, may I ask you how did u include the prepared tooth in the multiple isolation, usually its hard for me to descend the whole after the prepared tooth after losing the height of contour
Hi Nataly, I use bisacryl type of material called Integrity but you could also use PMMA (Jet acrylic) it just take longer to set. Hope this helps and thank you for following our channel
Hello, thank you for another great presentation. I am so thankful as you literally taught me to use rubber dam❤ Can you answer if it is possible to use the heated composite for cementation of the endocrown? When are the walls too thick to do so? And what are your thoughts on such cementation? I have read some articles on providing data on increased shrinkage of the material and have mixed feelings…
Hi, thank you for watching. I don’t use heated composite for cementation. I feel confortable with resin cements and have not had any issues with it for over 20 years. I think that using heated composite is a good technique but with its difficulties. The temperature in the composite does not stay for long (after 5 seconds there is an increase in the temperature and the composite is not that “runny” anymore), so you have to be quick and good at it.
Why do you reduce the height of the bucal and lingual walls if they have more than 1 or 2 mm of thickness? I think is better a parcial restauration that a full coverage restauration. It is the opposite of what study shows. And the most of cases are not endocrown, it is overlays in my opinion.wrong or not this is my way of understanding it, without criticizing your magnificent work and teaching. Many thanks
Jorge, I don't feel offended at all. I think that you comment makes others be aware of the different lines of thought that we have in dentistry. A couple of reasons I prefer the option I chose: 1. If you look at the buccal wall more than 50% of its thickness comes from the build-up I did. This is after I removed all the intermediate restorative material used by the endodontist. 2. An endodontically treated tooth behaves completely different that a vital tooth. By removing so much dentin to access to pulp (this was the second RCT performed) you decrease the stiffness of the tooth and its resistance to tension forces. By covering all the occlusal surface we compress forces and these are better manage by the reminding tooth structure. 3. The geometrical feature seen inside the tooth which technically classifies it as an Endo-crown is all done on composite. It did not require any additional removal of tooth structure. I agree with you when it comes down to restoring vital teeth which is alway the ideal (and my preference), but when the tooth is not vital anymore I rely in these well evidence supported concepts. Thanks for you comment.
This is so good, thank you!!
Thank you so much

الله يوفقك دكتور 🙏🌹
DR. we can use steps of bond one coat universal and coat activator in all types of restorations for example e-max (veneers - full crowns )?
Yes you can! Thank you for watching
Dr. Romero which kind of temporary material you use when you prep for overlay or onlay?

Dr. Romero which kind of core material you use? Dual core? Thank you
Any DC resin core build-up material will do it. I use Fill-up from Coltene. I do recommend letting it “DC” for 4 minutes before light curing.

@@romerodentalseminars Thank you very much for the detailed answer and the time it has taken you. I appreciate it a lot.
Is chamfer margin necessary?
Yes, for ceramic thickness. Thanks for watching.
At least how many walls you must have to make endocrown in endo treated tooth ?!
At least 1 wall with enamel
Hi doctor...is there is by any chance a way to communicate with you on social media like Instagram or Facebook
Look for us as Romero Dental Seminars.
