Thank You ! 🙂
Thanks for great set!
Thank you 👍
thank you!
Will a recording be available
Thank you somuch !!
Thanks
many thanks
Great presentations ! thanks Diederik
thank you guys.. a very nice one! KR and good night from munich. Denny
For injection moulding how do I get a good interpapillary contour and minimise gingival inflammation
Would you make a cantilever onlay in zirconia on a molar with an extension to replace a premolar, with bonding mostly on dentin but also enamel?
Any tips for cementing zirconia Maryland bridges ul32 3 is retainer
thank you!
Stefan do you prefer the Matisse or E_lab to make the crowns?
//Magnus
Thank you for response sir
Thank you for the excellent webinar!
From Edmonton,Canada
Which luting agent do you prefer for glass ceramics?
Why did you prefer zirconia crown at trauma case instead of lithium disilicate glass ceramic?
what are the hybrid indirect composites? as the labs are using graphene to construct indirect comp onlay. what is your opinion ? IS graphene used commonly ?
Are the injectables as strong as packable composites?even for posteriors?talking about the GC ones
Thank you for the presentation! It gave us a nice insight about selecting and using different materials for the aesthetic cases! Which type of dentin do you recommend using on the substrate before the injection molding technique?
So as an antagonist for zirconia you would use lithium disilicate for molars.
if you do a direct composite and you want to change the color .can you explain the procedure?
Thank you guys, very interesting webinar
Do you take into account bio compatibility and biologic toxicity when using products?
Can u plz explain Dahl technique that u used in one case
Which kind of cement you advise for facing which one tooth is colored , other not and you may not make two separate facing close to each other!
What was the year that you started to work with MDT located in another country? What is your most liked tool in your workflow to transfer “data” or info to MDT?
Hi!
This was very interesting
in a patient that is no bruxist and has no parafunctions; would you also do feldspathic ceramic veneers?
Can you explain a bit on strengths of E-max and zirconia in context to occlusal forces in bruxism patients. Which has the best longevity?
Many thanks for a great talk. How long clinically would you expect Lithium Disiliicate last
Your recommendations to bond zirconia indirect restorations
how long do indirect restorations (zirconia and lithium disilicate) last?
how to avoid the ultraviolett effect on Ceramic – how can i be sure that the Venner looks good in a discolight
?
and efcharisto poli
Why did you prefer zirconia crown at trauma caseinstead of lithium disilicate glass ceramic? I mean arent glass ceramics more aesthetic than zr?
Danke
Thank you for the great lecture, very informative!
thank you
What’s your recommendations to remove old indirect veneers
Which Photos do you recommend to send to the technician?
Excellen webinar
Thank you very much
What type if finish line for the crown,
Thank you both, very interesting présentation.
Fabulous respect from Zürich Joseph Guindy and Aleksandra Zueva
Thank you very much to both lectors for the webminar!
Are difference of porosity on Lithium disilicate materials when we use milling versus press technique?
How we choose?
the use of direct / indirect ? your opinion?
about the hybrid implant, is it a single block of lithium silicate, then zirconia and composite are added to the block?
Why did you prefer zirconia crown at trauma case instead of lithium disilicate glass ceramic? I mean arent glass ceramics more aesthetic than zr?
Are these techniques and the procedures affordable in countries like India where people expect quality as well as economy?
if the zirconia need adjustment , what polishing kit can we use to make it smooth
Would you prefer luting or bonding?
Good Morning from NZ
Dear Stefan, witch machine do You use for cad/cam?
Thanks. Povilas
what are your criteria to choose the material for veneers between feldspathic, LDS and zirconia?
how do you choose between cut-back zirconia and multilayered zirconia?
Why did you prefer zirconia crown at trauma caseinstead of lithium disilicate glass ceramic? I mean arent glass ceramics more aesthetic than zr?
how did you remove the old veneers in the last case?
What material do you recommend for worn dentition or do you combine materials as suggested by Dr Didier Dietschi-age and degree of wear
Do you do BOPT? another question
Hi
Can you stain ceramic in the mouth to try and avoid remakes
Is it possible to create aesthetic appearance and gradation in the natural layers of the tooth and transparency in direct compensation
and how long can direct compensation last in the long term?
Hey
What is the material
Good evening
can you mention time taken?
Good evening
Good evening
Hello everyone!
Hello
Hi
what material would you prefer in a bruxist pt- zirconia or metal
what material would you be comfortable using in a 47 that is # in a restricted envelope of function
Hello
Hi 👋🏻
Good evening
Hi everyone 🙂
Hi
Ist real that indirect last longer?
GC
What is the best insturments you recommend to finish and polish anterior esthetic composite and what is the sequence
Good luck guys! K.R. Ward
