Subject: [roots] thermafil removal and deep retroprep

This was a difficult retroprep. There was Thermafil in the canal, which was hard to remove, see rads,
it took quite some time.  My usual retrotips were too short, so I took out the surface lesion (SL)
tips by Spartan, I use them when the retroprep is longer than 4 mm. In particular SL 4A is very useful.

Thanks for sharing Marga. Excellent case. I have a couple of queries.

1. what size& type  of sutures do you normally use?
2. type of needle which you recommend.
3. which flap retractor ?

thanks in advance - Unni

Thanks Marga for the reply. Do you prefer 1:50,000 epinephrine when ever possible in surgical cases?
The field was looking great!.-  Unni

Yes, I always use 1:50,000 epinephrine - Marga

REALLY NICE CASE MARGA!! HOW DID YOU MANAGE TO FILL PROPERLY ALL THE RETROPREP? HOW MANY MILLIMITERS DEPTH?
DID YOU FILL IT ALL WITH MTA OR GUTTA+MTA? WHAT KIND OF PLUGGERS DID YOU USE. PACKING LOOKS GREAT AND IT IS
A RELLY LONG RETROPREP. THANKS FOR SHARE, JAVIER.

Thanks Javier,I filled the whole retroprep with MTA, and used custom made pluggers and the surgical retro
pluggers from Joey Dovgan. - Marga

Hello Marga,

Nice demonstration as usual. Thanks for sharing!

Have you tried the new 3-6-9 retrotips developed by Bertrand Khayat? I can't find them on the net right now
but they should be available (Satelec - Acteongroup). With these you can retroprep up to 9mm! They work great,
definitely worth a try.

How long did it take to place these 15 microsutures? - Maarten

Thanks Maarten,

I know the 3-6-9 retrotips by Satelec, and tried them on an extracted tooth. They are specially designed for
deep retropreps.

Hmm, hard to say how long the sutures took me, I usually spend quite a bit of time on suturing, I do this
through the scope. In general, I schedule 60-90 minutes for a surgical procedure, depending of the complexity
of the procedure. - Marga

Hi Marga,I am interested in the manikins that you use for your surgery course.  Can you show a picture of them
and tell me where you got them? - Fred
