I have tried everything-- even waxing UP TO the teeth and never having to scrape or clean them off before investing as they never had wax on them to begin with-- yet this problem persists. THERE IS NO WAX REMAINING AROUND THE CERVICALS (I know, I know-- but really. I am using a magnifier to check.)
About a .75-1mm piece of stone left around the cervical edge of the teeth after devesting. You can pop it off but the acrylic film remains-- and needs to be lightly chiseled around just rubbing over it with the back side of the chisel lightly-- VERY thin skin or film... almost seems like it could be separator.
If I pull a tooth out of the flask after painting w/ separator- the separator has not leeched past the cervical edge.
Investing with Hydrocal 105 yelow stone.
I would rather not use insulating pastes or puddies.
The rundown:
Waxing up to teeth- not going over and removing- wax never introduced on to cerv. past where waxed
NO WAX SOLVENTS APPLIED
All yellow stone investing
Tried 3 different waxes- To soften the wax--tried from 5 min all the way to 10 mins to soften the wax in boil out tank. Nope.
Pneumatic press used- 4500psi and have tried down to 3100 psi thinking maybe pushing past... Nope.
Two different separators... no way
Tried bench set 15 mins., no bench set.... un-uh
Tried fast cure, slow cure- nada
3 different brands of acrylic-- no
Not passing the job off to another tech. Hands on by me.
This is frustrating. Help me MOMMA!!!!
