Me again, the dentist asking all the stupid (?) questions.
I have in front of me the operating instructions for the Ivoclar Ivocap system, and it is to this system alone I will ask questions:
1. Purchasing this system, am I tied to Ivoclar's proprietary acrylics? For example, many here are telling me the best of the PMMAs is Diamond D.
2. Can premixed capsules of other acrylics be adapted to this system? Are the capsule sizes standardized?
3. The instructions say 35 minutes in boiling water for polymerization. Is this for their acrylics only, or for such as Diamond D as well?
4. The instructions say at least 30 minutes in flowing cold water, with pressure injection for the first 20 minutes. MUST we use cold water? That is, can I simply place these into hot water (non-flowing) then leave this overnight to bench-cool?
The reason I prefer the bench cool technique, for materials-engineering when quick-cooled micro-cracks develop, and the slower the cooling the stronger the resultant material, a point I expect most of you already knew, from your castings work.
5. What is the best flask to use in this system? Please state if closed or open, and the make/model of flask. If many different systems work, what is your favorite?
6. With this system, how much finishing is needed, after de-flasking?
I thank you.
