It takes A LOT of practice, I wasn’t very good the first 50 times! You can try a different technique that I’ve seen other assistants use with success- put the powder and water into a ziplock bag and squeeze/ knead it by hand, then cut a corner of the bag and squeeze it into the tray. Keep practicing, you’ll get it!
Wiping some alginate on the occlusal surface will help capture more detailed anatomy by pushing the material into the grooves and fossa of the occlusal surfaces; this reduces trapped air and getting air pockets on the occlusal anatomy.
I haven't used a curved spatula. I think the key, no matter the shape, is to really smash the alginate against the bowl with the spatula. It takes practice!
They are silicone cheek covers from the dental model company! I believe these came from Paradigm Dental Models but most dental model companies have them. You can even get a silicone tongue (which I removed for this demo).
I don’t believe they are significantly different. it’s the shape of the blade that’s most important. The all-plastic spatula is easier to clean because it’s one piece. However the plastic is not as durable and I’ve seen the edges get rough and notched out over time.
It sticks in the metal trays without adhesive - these are rim-lock trays, there's a roll of metal that helps hold it in. On plastic trays you want to use an alginate adhesive.
Everytime i need to review some labwork i somehow find my way back go your channel, thank you
I love watching your videos. They're insightful and you speak clearly and just slow enough.
Glad you like them!
Thank you Stephanine !!!!
thanks sister

Great video... can I use the same method and material to do a lower gum impression?
Yes you can! The tray is shaped difference - its a "U" shape for the mandibular arch.
I have done it more than 20 times and am still bad at mixing, what should I do?

Hey Dear Stephanie Derfus. What is the aim of wiping material on occlusal surfaces.
Wiping some alginate on the occlusal surface will help capture more detailed anatomy by pushing the material into the grooves and fossa of the occlusal surfaces; this reduces trapped air and getting air pockets on the occlusal anatomy.
@@StephanieDerfusoh thanks for reply . Greeting from İstanbul as a dental student
I'm also struggling to mix alginate and take to mixing alginate its difficult to me. We used curved spactula

What did you use for the cheeks/lips?
They are silicone cheek covers from the dental model company! I believe these came from Paradigm Dental Models but most dental model companies have them. You can even get a silicone tongue (which I removed for this demo).
Is there a difference between a plastic or a metal spatula?
I don’t believe they are significantly different. it’s the shape of the blade that’s most important. The all-plastic spatula is easier to clean because it’s one piece. However the plastic is not as durable and I’ve seen the edges get rough and notched out over time.
how do the alginates stick on the tray, do you use adhesive on tray before?
It sticks in the metal trays without adhesive - these are rim-lock trays, there's a roll of metal that helps hold it in. On plastic trays you want to use an alginate adhesive.
