Glenn,
You are right on here. One thing for certain, is that Biolase has figured out a few ways to combat their problem with trunk fibers. I also know, (knocking on wood now), that I haven’t had a problem, same fiber for almost 2 years now, and use the HECK out of my laser DAILY…just think how those LONG LONG LONG, just kidding, crown prep procedures heat up the fiber! Seriously, I have used and abused my laser purposely trying to blow a fiber, with no luck. I give credit where credit is due! Again, to Al, thanks for posting that post, it’s invaluable!
