Well done! I have a lab microetching unit which is enclosed and has a suction unit. Is there any concern with the aluminum oxide particles being released into the air in the office as far as air quality.
One way is to ask the Dental lab to put it in an porcelain furnance and heat it very, very slowly !!! to 350-450 degree Celsius for around 30 min on end temp. There's a risk the crown cracks because of the expanding tibase to quickly for the zirconia unfortunatly.
@@emelgiefro Done some basic research on a couple of papers written about this and apparently sandblasting can cause micro crack propagation if done too severely above 3.5 psi pressure and too close to the surface may I reiterate that this is only a brief research on my behalf and should only be treated as such
This has been written about in several studies and is included in th IFU of many zirconia manufacturers. Any microabraded zirconia should be run through a regeneration cycle in your porcelain oven.
That was excellent. Thank you for sharing!
Nice to see another dental channel watching this video too :). Subscribed to both of you. Thanks for the educative videos
Nice and clean work! Great presentation!

What about cementing them in the mouth and then take out to clean, and then place it back? There will be times that it won't fit properly, no?
very informative video.
thank you , one big salute for you
Thanks
Nice presentation
thanks
Great video, just a question, is this technique and material works with 3d printed temporal crowns? Thank you
I had cemented crowns on implants, bottom jaw, it feels really bad and food always getting under crown and cause bad smell
What about using glycerin on the margin?
You had extra cement material on the Ti base below the margin. very sloppy. You can take a BP blade and remove the excess before seating.
Do you have a way to separate the ti bases on failed crowns/bad shades?

Sandblasting Zirconia will cause the propagation of micro cracks and weaken the zirconia in the critical area .
Please correct me if I am wrong
No it wont
Using a diamond disc on it will

Can we light cure zirconia..?? Does allow light??

@@wendellmccall4453 can you elaborate on this regeneration process please sounds interesting and intriguing pending on temperatures involved
Steam?
Leave it to the technicians
