Hello, I'm having issues with PlastoDon N (Scheftner) heat cure material, whenever there's thicker parts of the denture (usually under molars) I get air bubbles, sometimes few, sometimes a lot, I'll show you pics when there's a lot of them, I use to use Meliodent, it was great, there was no issues at all, so my thoughts on this is that I'm doing something wrong and so far I couldn't find what, here's my thoughts:
1. Too much monomer? but I do wait about 10min and the material itself seems good to go (like Meliodent was),when it's too soft - I wait a bit longer, when it's too hard - I try to put it in faster (lol..)
2. Maybe it's the temperature? I put the flask with the material inside into the boiling water, I try to put it into almost boiling water, so that the flask itself would absord the heat right before the water reaches boiling point.
3. Since air bubbles are mostly inside the thicker parts of the denture - I was thinking maybe I need to put the flask inside the boiling water faster? because the middle part of the flask reaches the temperature last, and usually the middle part is thickest
