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.
