Zirconia Ceramics, Part 1: Vonlay Preparation #5 Natural Tooth
Vložit

- In addition to its great strength, zirconia has a number of important physical qualities that are helpful for dental restorations. Its color is close to that of real teeth, therefore less opaqueing or masking is required than would be the case with a metal substructure. Additionally, zirconia has good opacity. In this video, Dr. Richard Stevenson demonstrates about CERAMIC VONLAY #5 NATURAL TOOTH for Zirconia.

Thanks for watching! - Krátké a kreslené filmy
Fantastic as always Doc! I have learned and utilized more from your free videos than I did paying $500k for four years of dental school. For that I thank you, you have changed my dental career in a big way!
Awesome! Thank you for the nice comment.
I admire the way that you adhere to the fundamental operative and fixed prosthetics principles even though you employ modern restorative materials.👍👍
Your comment is very meaningful to me - thank you!
As always too good , doctor you make dentistry look beautiful and easy . I am too happy to have you my mentor .
Very nice of you!
Awesome subject. Thank you doc! You are the best.
Thank you Rodrigo!
thank you teacher
My pleasure.
Cool prep, I think about doing this occasionally, seems like leaving the palatal is a good service to premolars that seem to be prone to fracture at the gum line on full crown preps
Agreed - thank you for your comment and insight.
Thanks dr ... interesting video
If there is literature of crown preparation, please type it here
I appreciate your question! Just case reports so far, but it's a prep that we've been performing at the UCLA Center for Esthetic Dentistry for about 6 years with great success - Ed McLaren lead the push initially and we have followed the principles known for veneers and ceramic onlays, and combined the two. There is definitely a need to perform a Randomized Clinical Trial but I'm not aware of any underway as of January 2020. Thank you.
Hi Dr. Stevenson. I've done many of these restorations with great success & your videos have helped a lot. I do have a question though. If I am doing a (same day) CEREC restoration and I have proper isolation under rubber dam and completed my IDS, would there be a difference in subsequent bond strength if I were to etch and bond the enamel ring before or after milling the restoration? It's a ~35min difference between the two.
No difference at all. The more you can get done while it's milling the better. I've been a Cerec guy for 20 years and just took the plunge with a PM1 - wish me luck! Best to you, Rich
I hope you will notes links to all parts in one series in the description. I would love to see your great videos, but it's hard to follow parts in the same series
Done! Thank you for the suggestion. Search the library for "Zirconia Ceramics" - it has 5 parts.
What would be the appropriate provisional for this prep ?
I use a Bis-Acryl provisional made from a dx wax-up and Duration cement.
Hi Dr. Stevenson, thank you for all your videos! This is my first year as a dentist and i am wondering- how is it possible to use diamond burr without a water-cooling? Isn't it dangerous for a pulp? Thank you very much for an answer.
These were done on extracted teeth and I turn the water off to allow better filming. Having said that, pupal temperature studies are old and poorly done. The make generalizations and recommendations that do not equate with clinical findings. I ALWAYS turn off the water when finishing my preps.
@@StevensonDentalSolutions Thank you very much for your answer! And can I have one more question-how many rpm do you use for the finishing? Thank you!
@@veronikakucharova8111 Usually under 10,000 rpm
Am looking for the part 2, could not find it, is it available yet? Many thanks for all your teaching videos, always looking forward to it. God bless you for sharing your knowledge.
Not yet...stay tuned and thank you!
Excellent prep sir, I would ask about vonlay, i thought that we should not to touch the lingual cups as well as not to touch the lingual surface ?.
Oh, that would be possible as well - there are an unlimited amount of variations possible. This was one.
@@StevensonDentalSolutions thank you sir for your reply , may i ask you why you cover the floor of the cavity with flowable composite
Normally if deep, I'd use RMGI, but this day I reached for the flowable simply to block out the defects and provide for a smoother wall. Not needed, but nice to do for the lab - they make better restorations with super smooth preps...Thank you Doctor.
nice, sir.how are you going to bond the zirconia to the tooth??? why zirconia and not emax? also on the provisional stage how are you going to prevent strong bonding of provisional material such as TELIO by ivoclar to the immidiate dentine sealing layer?
best regards
I did a quad in e.max in a previous video, and since Zirconia is so confusing to docs, I thought I'd show how it can work in certain cases. Preps must be more retentive and the zirconia APC bonding protocol must be employed. After IDS, I place glycerin over the adhesive to lessen the air-inhibited layer and minimize the provisional from binding, then use Duralon cement. Thank you for the thoughtful question!
@@StevensonDentalSolutions thank you for the time spent doing videos and answering questions
@@83eitanfog My pleasure and thank you for the questions.
How would zirconia be cemented? Is it possible?
Coming in the subsequent part, however, a preview: APC - air abrade, primer (MDP) and composite cement. Chemical bond, not micro-mechanical - will it last? The work from Marcus Blatz says yes... more studies will help us for sure.
speechless
Hi Kia - looking forward to teaching with you at the center. Thank you for your support.
Hello, I'm the manager of a dental clinic in China. My six doctors and I have learned a lot. Now there are many things that we can't understand. My English is not very good. I will study hard. Thank you
Great - I'm sure you will! Thank you.
Stevenson Dental Solutions Thank you. I'm very happy to get your reply. Our doctors like your videos very much. We don't allow youtube, but we insist on subscribing to your videos
@@user-pt7wn3mx6z Great - wish you the best!
Dr. Why do you fill the cavity with composite or glasionomeer? Isn't the prep ready for the onlay?
helps to remove undercuts and preserve more tooth structure.
