Same here.
Think it largely depends on the number of extractions on
how successful the 'one shot' can be.
Ususally take all molars and most bi's (depends on occl.)
Let that heal for a while before taking an impression.

Rarely have to remake immediates, but there are some.
Guess it depends on how good the impression is and how
good is the lab.
Been using the same removable lab for ~20 yrs now.
Consistent quality and we work *together* on cases.

Have one of those 'denture mills' nearby.
End up fixing alot of their screw ups by starting from scratch.

Interesting.

To start out with it was all about crowns.  I had to wear a "splint" for
6 months before to change my bite.  There was never any discussions face
to face on the condition of my bite.  There were x-rays, etc and the
dentist, my insurance company and my workplace & I talked about on how
long this and that would take and how much I would pay and how much my
Ins. would pay and exactly when to pay it each month.  I remember after
that time nothing was said until just 10 minutes before he started
filing down my first tooth, he said "you stay out of it, we know what we
are doing".  What a convenient  time for his sake to bring this up.  I
think that was the beginning of the end for me right there.  I was alone
and too far into this that I could not get up and walk away, I didn't
think and never dreamed I would be having to go thru this unnecessary
hell the rest of my life.  I was wearing something temporary and during
a dinner my work had and sitting at a long table with my co-workers and
bosses, I did lose a tooth - didn't swallow it, it fell in my plate.
This was just one embarrassing thing that happening in trying to get
different teeth in my mouth to satisfy them (not me).  They took control
over my whole being.  Eventually, I lost it (almost). I was in such a
fog trying to deal with this pain and teeth in my mouth, trying to hold
down my job (without a job I had no income) and teeth so long  that felt
like they  should have gone in a horses mouth.  I had short teeth and he
put in long teeth within a  months time and I could not adjust to them
evidently.    I was living in so much pain in my face and neck and like
I said it seemed to throw my whole body off eventually, I think to try
to compensate for the pain in my mouth and my jaws.  I would then
started tightening up my whole body when anyone would approach me as my
work was giving me hell for not doing my job.  I got to where I couldn't
remember to many things. (I was a secretary at a large company).  I
would take a message over the phone and had to rewrite it 3 times before
i could get it legible.  I would go out to eat with the girls at lunch
time and end up just sitting there staring into space with my hand over
my cheek cuz it hurt so bad.  Of course none of them understood what the
heck I was talking about when I mentioned the pain in the face and must
have thought I was really going off the deep end.  I would complain to
the dentist and it just went over his head and we got into arguments.
Again, I didn't know enough about it to know what questions to ask or to
know what to expect right off the bat or what was to eventually
straighten itself out.  Down the road the one prominent doctor (maybe
neurologist- I had been to plenty of them).  This one said I had
Fibromyalgia.  By this time I had heard of this.  And by this time I had
gotten my Webtv and found a TMJ Group.  As expected all my tests came
out negative seemed like for anything I took.  After the crowning of the
teeth it felt like my whole face had fallen and I felt I didn't have
that automatic smile anymore - to me it felt like he shoved my teeth
half way down my throat and I had no support.  I think now that I am
able to sort things out and pinpoint different problems that I feel I
need this upper denture to come out further to my cheek  so i have that
support.  I was left with so many problems before I couldn't pinpoint
anyone thing what was wrong.  AND, now I wonder about this bite - if my
mouth/teeth should go straight up and down when I chew or upper rub
across the lower ones???  On top of everything else as much as I do like
this new dentist, she is from China or Viet Namese (sp).  It wasn't so
noticeable because she had her assistant from the U.S. there to do most
the talking where after I got the permanent denture, she was alone with
us and I was just worn out trying to understand some very important
things she maybe was telling us and for me to try to get across to her
how I felt.  I just don't know what my "rights as a patient is" and its
like its a secret and i don't want to cause anymore hard feelings.  I
was left with being so misunderstood and hard feelings over all this by
so many people.  Theres enough problems in this world, I just need for
this to go smoothly.  I had two bad marriages and ended up raising 6
kids alone and I was going to finally have a life of my own then I get
the word that these teeth have to be done or else.  My problem then was
just that I put tension in my jaw and, yes, my teeth were worn down
otherwise not much problem with my teeth.  After all the bad marriages
and raising the kids, sorry to say  these  dentists were the ones who
BROUGHT ME TO MY KNEES.  it was tho they took my control away from me
and this was something no one can fix themselves so I had no choice at
the time.  Funny, even my grandchildren know.  One bought me a pin for
my last birthday saying "I've Survived Damn Near Everything".  I told
her i was going to wear it on my purse for ever  and I would carry it
to my grave.  Joyce-MN
