Overzealous Post Space Preparation.

Dentistry November 28th, 2006

Ignoring the periodontal issue with the 6, there’s a carbon fibre post in the 5 and it seems to go all the way to the apex.

I decided to try to retreat the endo because apical surgery would wack too much of the root off and create a very unfavourable crown to root ratio.

During the retreatment the radiopaque areas turned out to be residual gutta percha, and the post did indeed go the apex. I ended up thinning out the root so much apically that a perforation developed and I lost a fragment of the post into the periapex. The tooth is currently medicated with calcium hydroxide paste. We’ll see how it fares over the next couple of weeks. Prognosis is currently guarded.

    eek! i wouldn’t hold my breath for that tooth – this person’s best bet is probably bone grafting (at the site of the defect) and implant placement (same goes for the 6). was it difficult to get that post out? i tend to use variolink bonded composite resin cement with those types of posts and my specialist says those are a bit trickier to remove, as opposed to the titanium threaded posts which can be ultra-sonicked and threaded out. as a general rule, i try to avoid posts, period, and i have recently seen the light and have switched to cast posts on the off chance that i do need one.

    Metal posts are always easier to remove (for me anyway). I usually have to destroy most of the non-metal posts before they start to move. My ultrasonic tips take a beating when I have to do that.
