Nice Jeff,

About how much tissue do you think you removed? It looks like about 3mm of new clinical crown…

There was a core build was done w/ bonded composite, that makes it look like more exposed tooth.
I only exposed a mm or so of crown.
Can’t impinge on biologic width.

Hi Jeff,

Looks good. I see a fair amount of cases like this and I feel that they are among the most difficult to treat with conventional resective surgery. You made it look easy.

I was curious if you used the standard 360um fiber for this case.

Hi Jeff,

Looks good.

What’s the deal with biological width? I’ve noticed it being mentioned in a couple of your posts. An inside joke?

Andy, Andrew,
All my Nd:YAG cases are now done using the 360micron contact fiber from MDT, Before this year I used 320 micron fibers. These new fibers seem more durable.
The reference to biologic width come from my Dental Town Case presentations and a case published in the DTown magazine in February, one anti-laser heckler could not get off me on biologic width. Glenn and others now include pictures w/ a perio probe on laser cases to keep the subject from starting again.

Hi Jeff,

Thanks for the background.

The use of a probe is indeed a good reference for all, not just to quiet the peanut gallery.

Here is a photo of the PerioLase MVP-7 handpiece w/ 340 micron quartz contact fiber in place.
