Fx'd Emax #8 - Pin Buildup- By Thomas W. Mitchell, DDS, FAGD

Introduction: 

From this week, #8 Emax done in 2009 with 6,7,9,10 and 11 with angular fx just above tissue on the labial and 3 + mm's above tissue on lingual. On the day it fx'd we recemented with 3M Ultimate and it actually held up for a week. So this is prep day

I just love seeing getting handed stuff like this...

From the day he broke 8 we can see there's plenty of length below the margin on the lingual as I had left at least some of the cingulum intact.

We recemented that day with 3M Ultimate

From the facial the fracture's at tissue level

Form the lingual we can still gain some prep length.

We isolated it and got the dentin clean.

Then placed 3 manikin pins

And co-cured Surpass 1,2,3 and Titan A2 Flowable

We blobbed on A2 Anchor and did the initial prep

Then packed the tissue with 00 cord and did the final prep.

From the lingual you can see how much prep length we gained. So even with the fracture we've got a good ferrule.

From the occlusal it even draws.

Conclusion: 

We sent him to the lab for shade matching and have him scheduled to finish in a couple of weeks. I like using these small pins in these situations as they give us a little more vertical length for supporting the buildup and eventually the crown. They're small enough to limit the damage that we all know self threading pins do as they're placed. That's a "trade off" but I believe I'm gaining overall strength of the restoration. Hope this helps you with some of these difficult situations.
