if your patient's crown fell off, do you re-prep the tooth and have a new crown made or just recement the old one?

Unless the tooth and/or the crown are compromised somehow (secondary decay, etc), you can just clean them off and cement it back on.

Bill was right. Also, the plan of action might also depend on WHY the crown fell off originally. Perhaps there wasn't enough cement space, or some other factor with the seating of the crown.

What aphistis said. Just make sure the crown still fits and the margins are still good. If the patient bit down on it after it came off it may have warped. Next time don't use bubble gum to cement it in. 😉

I had a first today for me. I was trying in a crown on #3 on one of my patients. I had adjusted the interproximals and the crown was fully seated. I go to check the occlusion and instruct the patient to close on the articulating paper, and as he makes contact between the MB/DB cusps of #3 and the DB of #30/MB of #31, right before my eyes, 90% of the buccal porcelain of #3 fractures off 😱
After picking the fractured pieces of porcelain off my patients tongue with a pair of college plyers, all I could do is ask my assistant for the temp bond and the old temporary and tell the patient what just happened
After looking at the crown before I sent it back to the lab, I found out that when this lab tech wanted 2mm of reduction over the line angles it was so they could put 1.75mm of metal and .25mm of porcelain 😡 🙄
On the flip side though today, the owner of the excavating company thats doing the work for my office's addition let me "play" around in the steam shovel excavator at lunch today 👍 I felt like I was 4 years old again playing in the sand box with my Tonka trucks 😀

Dang those labs! I had one lab guy who couldn't get the esthetics on a 7 unit bridge right. I think he tried a total of 6 times which included redoing the entire bridge over twice. Last I heard of him he told me he would get the bridge back to me ASAP. Thankfully I went with another lab after the first few of his failed attempts and that 2nd lab got it perfect 2nd time around. Luckily my patient loved my temp and didn't blame me for poor dentistry, rather a poor choice of labs. One of those "memorable" cases I guess. 🙂
