Hi folks: I have less and less time to post these days with all sorts of deadlines approaching but here is a case I did last week.

I had a patient come back complaining of a crown that my former associate did for me which left an open contact.

I told the patient that I would get the crown ( On with tempbond) off and add some porcelain to the crown.

Well I tried to pull the crown off and of course the whole core and post came out leaving me with a stump , even with the tissue.

Now fortunately he had some perio disease so I thought that I better see if I could find some solid tooth under the tissue and remove some bone with a closed flap situation (not much bone to remove).

I placed a post in the tooth (fiber post) and cured it with the argon which leaves a brown dot on the post. Quickly built up the core with resin by hand and then needed to remove tissue and bone to get a good ferrule all the way around.

Used the Delight without water and a thicker 600 micron tip to start with at 30 hz and 100 mj without water on the tissue. Once I created a trough , I used a 400 micron tip to remove bone with water at 30 hz and 135 mj with very little air.

I then finished the margins with the diamond, tried coagulating with the argon, and diode without success (he takes aspirin) and I was running short of time so I cheated with a little viscostat. Took the impression and placed the temp all in a little over an hour. It was frantic but the erbium saved me there.

Will post the finals when they come back. I am still wrestling with when open and when closed flap is best.

Just another tool in the toolbox right.

Hope you like it, its been quiet around here.

Take care.
