Good day Doctor Stevenson. When you use your microetcher II A from Zest to sandblast your zirconia crowns, I believe we have to run it at 35 psi for 20 seconds. Can we use 60 psi for 10 second? I have a hard time to adjust the psi from my dental chair system.

Great job dr. 330 RGS is the same as inverted cone bur ?

Would you please make a video show us the correct use for amiror in the indirect position.....❤thank you doctor

This video is really special due to the fact that you have shown real time problems during restoration and ways to tackle it. The best instructor for those who want to level up their restorative dentistry.

we only get 1 type of rubber bur and its one of the circular ones that follows the shape of a lingual fossa. even when i put my speed at 6k i still find it taking away from tooth structure what am i doing wrong

From lebanon thanks ❤

Thank you so much. It is the most comprehensive demonstration of preparation. Really appreciate it.

Whenever I use a clear matrix and pull it to the side to adapt it and light cute, the composite always gets stuck to the matrix and moves things around and it never looks as flat as yours. How do we prevent this? Thank you your videos are amazing

Dr Stevenson can you please make a short video on how you did the stent used in this video ? thank you so much .

Thank you, Dr. Some references mention that beveling for amalgam can be done only at the axiopulpal line angle. However, you mentioned it can also be done on the gingival seat. I just want to confirm: would beveling in that area compromise the strength of the amalgam?

Hi Dr. Stevenson. I am going through your gold inlay and inlay videos, my observation about this MOD hollowgrind prep design is that it seems easier and less technique sensitive than other Tucker techniques. Is there any disadvantages of this? I’d love to take your course someday and learn these techniques

👏🏼👏🏼👏🏼

It should be mounted not hand held

Thank You Doctor

Hey doctor Stevenson were you using high or low speed?

perfect.... thank you for video

thank you for the clear explanation

cảm ơn bạn

Great work

Thanks!

It is really amazing. Thank you so much for posting this Video. Huge help! ❤❤

That part Dr S said it's been fun spending the last few minutes with you. Thank you so much for your generosity and kindness.

Sir you are done great work i am really thankful to you for my all dental clinical skills are improve when I watch your videos ❤

Great video. How do you prevent j lips or correct them at the contact areas?

Thanks

Hi sir, where did you buy the dental models you show in the video?

How long does the feeling last on the front teeth?

Thanks

Thanks

Steven son 个人啊才是 迫人 图必得 有啦inform

Watching this a few hours before my exam. So help me God 😂

Thank you sir!

although I'm not good at E language , I do understand u ❤️❤️❤️❤️ Allah appreciates and protects u❤️❤️❤️💟

Very helpful series, thanks so much doc!

as layman patient the amount of tooth structure that must be taken away to put an onlay is worrisome. There is not much left in case decays happens again. I wonder what's the total life expectancy of a tooth with onlay. I also thought it's better to preserve as much as possible enamel. But perhaps this all depends on what's left after removing decay.

❤ Amazing always. But I have a Question. Margins of the preparation should be Subgingival or Supra gingival.

Hi Dr. Stevenson! At 10:25 you mentioned that to extend the gingival floor more gingivally we would need permission from the floor examiners, but I also noticed that the gingival clearance at that point still seems to be less than 1mm. Do we still need permission to extend the proximal box more gingivally (to almost 4.5mm measured from the occlusal) if the gingival clearance is still less than 1mm? I've noticed that due to the anatomy of the teeth that I've been using to practice (DTX ones) the gingival clearance seems to be always less than 1mm no matter how gingivally I extend the box. Thank you so much for your help!

Thank you doc your helping me so much for my externship site. I appreciate your help a lot! ❤😊

How to support the contra properly?😮

That's not Fletcher that's Arthur from possibly in Michigan

I can see an undercut in that preparation. I don’t know how a patient can wait so long with open mouth…

Wowed!!

Great job. I do recommend you no longer introduce bonding resin to uncured composite on a micro brush. There have been studies showing that it can affect the properties of the composite causing it to underperformed. Composite manufactures are recommending this as well.

where can i buy this bur ?

عندي امتحان بي باجر شكرا دكتور 😢

Watching you from Iraq , thx dr 🤍🫂

Hello Dr.! Thank you for your video. Just can you tell me if prep premolar class 2 composite is it need convergine one wall and orthogonal another (depending upper/lower)?
