A few weeks ago, I constructed a temporary 4 unit bridge on lower left
posterior(18-21).  She is missing teeth 15 and 16.  I made #18 thick
because she was going to travel 1000 miles for a wedding and I did not
want it to break.  The next day she called me complaining of opening
her mouth.  I told her it could be the injection shots.

She came back from her trip, did not call me, but saw her physician
and he gave her antibiotics.  I saw the patient a few days later, she
had a hard time opening her mouth.   The problem: the temporary bridge
caused protrusive interference.  I put the real bridge on, and all her
symptoms went away.

She was a new patient I had seen months earlier. and I took her out of
group function then.  She was so relieved after I had taken her out of
that occlusion.  She had complained of "TMJ" problems.
