Crown Post Cementation and Seating- By Thomas W. Mitchell, DDS, FAGD

Introduction: 

Her son graduates tomorrow from high school so she's in a panic holding #8 in her hand! We restored #9 last year as an implant supported crown, but 8 was done before me ("BT") and is a beautiful all porcelain, probably Emax, crown. We're booked solid today so we found 20 minutes to do this.

#8 endo tooth. Certainly this is a good endo fill and result.

Opp! Son's high school graduation is tomorrow. #9 is our implant supported PFC on a zirconia abutment.

I've got about 15 mins to do this. My next pt with a Bisque tryin from 6 to 11 is now waiting.

Top 10 mm's GP removed first with a #3 Peso reamer, then shaped for a #2 B DT light post. The canal was wide enough so the #2 drill went to length without binding.

#2 DT light post bonding in with Surpass 1-2-3 and White Anchor. After that I shortened the post (but no photo, sorry) to about 3-4 mm length.

Now to hollow grind the crown

Lots of tooth remaining inside

I'd remove a little, try it on, remove a little more, try it on, finally went thru the lingual before I could get in on prep/post complex.

The whole thing now is starting to fall apart, but it fits over the post.

Then cement with Interface-Surpass 2 in the crown and Surpass 1-2-3 already on the prep and Anchor A2 shade. The cingulum area fractured off as soon as I got it seated completely.

I bonded some Exquisite composite over the cingulum area.

And now she's off to graduation.

Conclusion: 

If you've got a good system in place for doing bonded fiber posts this is a relatively easy procedure
