Hi Trisha,
Now that's a fun time ain't it???
I just love it when one dr figures your doing something incorrect. I make these type of clasps quite often as well. I have one guy that thinks sometimes they fail to often. Like yours, the appliances are a year old or older. Your method is just fine. Continue to communicate with the dr that your doing things in an unchanged manner. You haven't changed solder or torch technique or flux etc.
Remakes sometimes don't only seem to come from one office, they do. That seems to happen in cycles with various offices. Your cruiseing along fine, then, one office (take your pick) starts having some problem or other. I don't mean to minimize the problems, they are real. Just sometimes, you have to deal with them, focus on them, they will go away. (the problem, not the dr.)
Years ago I stopped chargeing for any repair work what so ever. Today I got a call from a women, her son lost his retainer. She used to work for a dr I work for now. The retainer was a few years old, her son left it behind in a restaurant. Gone. She works for another dr out on the coast of Oregon now. She was surprised to here she could send a model to me, with that drs pres., and there would be no charge.
Remakes and repairs are few compared to the amount of retainers I make. Sometimes it seems like repairs and remakes come in batches. I have never been able to put a definet cuase on it. I just find that it's easier and quicker to just fix the darn things and move on, no charge. No charge has been great P R since I decided to go that route years ago.
This guy your dealing with, I hope it goes well for you, pain in the butt it is.
It will pass, your work is great, you've posted some pics here.
Mike.
