Does everyone's doctors utilize the muscle trimming technique for better establishing the borders of a denture? To clarify, My dentist has all the assistants taking impressions pretty much except for washes and relines. They just put the alginate loaded trays in the mouth and let the borders go where they want to go, doing no manipulation of the lips/cheeks whatsoever. They don't do final impressions, as they don't think they are profittable.

I can see just fine on a proper cast from a border-moulded final impression. I just had upper and lower relines yesterday, went to deliver and I had to reduce the periphery on both by 4mm. Dr. told patient to just use fixodent. The doctor took those impressions. That outcome upset me, not because of the extra work but that relines should fit pretty much right off the jig. But what did it even more was the Dr. coming in at the end of the day and saying they "don't know how many dentures I have finished but they want to get somebody in to help me. Not that I'm saying you don't know what you are doing.....Every lab tech we've had here has had a tough time knowing where to finish to", No, that's EXACTLY what you are saying. I know what I'm doing just fine. So I am going to have a talk with my corporate boss, because either I need to get good at defining borders on crap models, or they need to take proper impressions. But this daily adjustment of every single denture is exhausting insanity that makes me reeeeeally sad.
Thanks for letting me vent. I'm a little heated.
