Screw up case - Courtesy ROOTS

Subject: [roots] Screw-up du jour

I fractured a K3 35/04 in the mesiolingual canal.....:-(
and  tried for 1 hour to get it out, but it didn't work......:-(
There was a lot of drainage from the mesials, 
so I rescheduled the patient in a month.

Today she returned, completely asymptomatic. I gave it 
another try, with the same procedure as I used the first visit: 
Bypassing the fragment with 2 hand files, braiding them around 
the fragment, and pull with a hemostat. I was lucky, after a 
while it came out, see pic.......:-)) I glued it to a sticky
pick to take a picture, I felt great.....

My happiness didn't last long, till I saw the final rad.....:-((
Due to my removal procedure, I had ruined the foramen, and 
ended up with a parallel prep....:-( and a grossly extruded 
filling....:-(

In retrospect, I should have used MTA........oh well........
......these cases make you humble....Marga

Marga, do you have any feeling for why the K3 broke? - Simon Not really, but it could have been the usual combination of a multiplanar curve (MB and ML were confluent) and torsional fatigue.- Marga Dear Marga, I know quite a few people who should be happy if their good cases looked like that. Don't worry, it will work. Winfried I'm betting it will be fine, Marga. - Guy W. Moorman, Jr. DDS It is all a matter of perspective. From marga’s perspective it was a screw up. From my perspective, it rivals some of the best work I have ever done. See. 2 different perspectives - gary
