    Hi Mark……..no I wont be at the Greater New York.

    Contacts for Global are…….

    1. Erin Boyd – Vice President
    2. Jeff Kopp – head of marketing and head of international sales.
    3. Sean Ryan – eastern regional manager.

    4. Sales reps who might be there for NY include Mike Mack and John Kuzmik (sp?) as well as NIck Forster from the DC area.

    Global is a good company and they are committed to customer service and support.

    Get them to put a loaner in your office for a couple of weeks so that you get an idea what you can see and also understand the learning curve.

    See if they will throw in the cost of a training program at Newport Coast Oral Facial Institute which is where my buddy Rick Schmidt teaches in Cherilyn Sheets and Jacinthe Paquettes facility.

    You can check it out at the following web address:

    Take care I am off to get some more rest.

    Let me know how it went with the scope.

    Hi Guys and Gals–

    Here a REAL different use for any laser–even erbiums.

    For spot-melting green compound during denture border moldingto smooth out and soften any wrinkles before placing it back in the mouth. Much better control over the heating of the compound.

    Isn’t that a HOOT?

    It works in a defocused mode for smoothing out the wrinkles in the compound after getting the first impression.

    I’ve shared this with people who don’t have lasers and I get the funniest looks. Ha! :biggrin:

    Are you feeling any better?

    Cool Bob………..gosh another cool thing. I have softened GP in obturated canals with my argon in a defocussed mode.

    Again another photothermal effect.

    Great stuff Bob, but what else is new.

    Glenn

    Bob I have a question for you about Nd:Yag.

    I had a guy a while back tell me about a lawsuit involving Nd:Yag and an apicoectomy where apparently a necrosis of the bone ( I guess due to improper settings and use of the laser) happened.

    Can you tell me what happened as this is something that guys on my endodontic forum have mentioned before. Apparently quite a few knew of the case and it must have been in the JOE or something like that.

    Graeme,
     Sometimes, the software needs to be recalibrated. You might call the service tech. I have not had that happen to me, but, if the unit gets out of calibration, sometimes this is the way it reacts. Mine, skipped pulses for awhile, had it recalibrated, and it works great. Hope this helps!
    Mark

    OK. Looks like a calibration issue.
    Cheers

    Sent the above h2o/air question to  my Biolase rep who forwarded it to Ioana who I believe to be their R&D V.P.
    Below is the response:

    QUOTE
    The air and water ratios do not have to be 1:1.  In soft tissue some doctors like the air and water spray even at settings as for hard tissue cutting (keeping in mind fluid entrapment conditions when increasing the air and water settings).  Other doctors prefer very low water and slightly higher air (for example 7% Water, 11% air)or none for controlled coagulation. To summaries the settings do not have to be 1:1 it depends on the tissue consistency, type of procedure and cutting technique (focus or defocus).

     
    Guess I was looking more for something that said ‘if you increase the water higher than the  air you can expect this kind of change in the cutting behavior of the laser’ or vice versa. Guess this is one of those experience things.

    Hi Gang,
    Being a baby laserdentist/microdentist every thing is new and first time. Today I “anesthetized” tooth #13 which had an MOD Irm temporary in about 30 seconds and then removed the temporary with my high speed on a rather touchy patient with no problem. Finished up as needed with the laser and restored in no time flat. Great experience – no shot and no pain. I am looking forward to “anesthetizing” a touchy abutment prior to cementation or etching or what ever. Feels great. Used a hemostatic agent today after digging out a sub gingival cavity. No weeping into the prep. Thanks for the guidance. Keep the info coming. I tried to punch a hole in a procera crown I wanted to open for endo that did not work. With a little kindling we could have stated a fire.

    Al,
    Thanks! Why when I see your handle do I think “swampman”? Is Clearwater in the Everglades? Just joking.

    Great Pat, Now I need to ask, what settings are you using for “anesthesia”? Just wondering. We are starting to research what porcelains we can “cut” through. Some have just enough stuff in em that we do the old Bill Cosby routine…”schmmmmoke!” I have removed others, it’s been interesting. Keep up the good work. You are starting to really come up to speed now it seems, how fun!

    Laser Crown Prep Case Presentation:

    This afternoon I prepared tooth #19 for a porcelain fused to noble metal crown on a 30 yo male. My objective was not to duplicate what Mark Colonna is doing but simply to ascertain if some of Colonna’s technique can be incorporated into a crown prep procedure. Many people, including myself, laughed when we read his initial posts.

    Profound anesthesia was established. Second photo shows my gross reduction with the Biolase Waterlase set at the 6 Watt enamel setting. Third photo depicts my prep after smoothing with a diamond in an electric handpiece. In this photo, the Waterlase was used at the 1.5 Watt soft tissue setting for gingival retraction.

    Treatment time from first photo to third was 30 minutes. My objective was not speed, but simply to determine if SOME of what Mark Colonna suggested can be achieved by another dentist. I believe the patient benefitted by a 90% reduction in use of rotary instruments.

    Comments, questions and ridicule will be well accepted.

    Photo of my impression from the Laser Crown Prep Case.

    If I don’t respond to questions/comments/ridicule for a few days it’s simply because I’m leaving town for Thanksgiving.

    May all of us have a wonderful Thanksgiving and enjoy time with our families!!!!!

    Happy Thanksgiving,
