Inline has a pink opaque paste?
I noticed you don't have lingual handles this time but realized you did a frame try in.That must have been tricky to dust the opaque and keep the abutments clean.
I always forget the handles on screw retained crowns.
Al, I don't want to jinx ya but you heard it from me first...
The lack of metal support on the ling cusp and around the access holes on the occlusial table may come back to bite you in the ass. I know your trying to not show any metal but on FMR where there is zero give to the appliance the glass will fail easier than your used to. I know your going to be doing the upper next just a word of warning when you develop the occ contact up top near these access holes.
I like how you dust with margin porc SMART!
Thanks for sharing the progress
Yes I forgot the "twitters" or bird penis's as Doug Jackson named them.
What a pain it made it to handle without any place to lock hemostats to.
Hey Al. try using those diamond tipped, thumb screw forceps. They usually come football tipped, get a couple and change out the tips on one of the forceps with a couple of tapered diamonds. (ask your local account for a couple) Nice for fitting into tight spaces
This is the 2nd enamel bake and final seperate bake for the teeth forms.
Tissue porc next.
Just out of curiosity Al, if the bridge is retrievable, why not process the tissue in resin? It would save the whole assembly from being subjected to any more firings, probably look better, and would be easy to modify in the event there is any tissue remodeling.
Sorry if this question was already asked.
I like GC gradia for this but the retrievability and the ability to repair a defect in the glass down the road sure makes stripping the resin a chore.
Why ? Because I dont know how.
I dont have much acrylic but I think this is something I need to learn.
Thumb screws? Does that lock them open?
