Hey, just curious about this. I have fired my zirconia (ivoclar prime) I apparently use some black magic voodoo when contouring and polishing so when I fire it can sometimes come out 1-2 shades darker. Ivoclar says i've excited the color ions by grinding too hot. Maybe so it does get hot with...
I am having trouble making my implant models,

I am curious what people use for their tissue compression(basal) number in exocad. I typically do -.03 on pontic sites. I am mainly wondering what should be done on a maxillary hybrid I dont want air infiltration, but also dont want it to not fully seat. What numbers does everyone use?
Hey my custom abutment and crowns are either too tight or too loose and always seem to need a ton of adjustments to get them to fit properly. I am not getting that seamless transition between abutment and crown I want. I design both and then mill both and when I go to marry them they just don't...
Anyone know what a RF clasp is?
The case is for 2 splinted survey crowns 5+6
L rest on 6
M rest n 5 with distal guide plane and a RF clasp on 5.

Anyone have a partial denture framework suggestion? I only do 2-5 a month if that and bertram is not interested. 3drpd doesn't have it down yet either.
I have some ill fitting bars, they are chrome cobalt, can I section and cast to to repair them or do I have to solder or lazer weld? I would prefer the strongest option
I have a case with a custom abutment, we normally print our own models. How can I print what the custom abutment would look like placed in the mouth? I basically want a solid.
On my cellphone so couldn’t dig through archives. Are there any tweezers/hemp stat/pliers for stain and glaze that aren’t rediculously expensive but yet still solid for years to come?
Is there a type 3/4 non resin stone that has excellent flow like flowstone but is less expensive? I want to try to use it as my top cap on the ivobase. The stuff I use is too thixotropic and I end up diluting it and losing density.
