Subject: [roots] Complicated crown fracture

This little 8 yo boy was referred to me because he sustained a trauma 
last year, at which he had a (un?)complicated crown fracture on tooth 11. 
His dentist tried to restore the tooth, but as you can see on the first 
rad, he didn't succeed to make a well sealing restoration, the cervical 
part of the fracture was not addressed. After a few months, he developed 
symptoms, a sinus tract appeared, and he was referred for an endo, still 
with the failing restoration in place.

I thought it didn't make sense to refer him back to his dentist to have 
the resoration replaced (why didn't he do a proper job right from the start), 
so we decided to do the restoration first, and then do the endo with MTA.

After a gingivectomy, I packed a cord, and was able to keep a dry field. 
A BU was placed, and the tooth was ready for an endo. Ca(OH)2 as interim 
dressing, next session MTA, and at third session, the case was finished by 
placing a post. The gingiva looked already better, although it is difficult 
to clean the site.

I used LuxaCore to do the BU, this is not a proper material to serve as a 
cosmetic restoration for a long time. You can see that it is a bit gray, 
but for the time being, it does the job. What I sometimes do is make a 
veneer of a microfill composite in the core material. I decided to wait 
for the first follow-up to see what it would look like. If necessary,
orthodontic extrusion can be executed, and probably he will need a veneer 
in the future - Marga

complicated crown fracture

complicated crown fracture Dear Marga A very nice result indeed. Can I just ask: What was the final apical size? Did you use a periapical matrix? How did you condense the mta apically? And finally do you find it easier to veneer at the chairside with microfill rather than have a laboratory veneer made and fitted. Personally I have been using Gradia composite veneers(laboratory constructed)recently an I find it easier to fit the veneer at a further appointment. Admittedly it is an extra visit but I am interested in your technique. - Jan Skrybant
