    Well,

    Hard to top Glenn’s Kudos to everyone.

    Dittos! Dittos! Dittos!

    Paul Newitt deserves a lot of credit for bringing everone together and pulling it all off.

    My appreciation to Andrew for giving me a drive tour of the area–very nice to do that! Love his office cooler too!

    Vancouver is a beautiful city, nice people, cosmopolitan, active, health conscious. The dentists are so very nice and polite to all us speakers, too! Janna said she loved it and would come back. That’s a major endorsement from a VERY picky traveler.

    It was really great to meet and hear such great speakers in those Paul arranged to attend. That’s not easy to do and pull it off so well–Scott Parker, and Ray Becker were new to me. Great guys too!

    Great topics related to clinical practice, not just lasers, like David Kimmels well done lecture on niche marketing.

    I’m really excited for this group and how it is shaping up to be more than just a laser study club, but a high-tech dental practice symposium.

    Last and hardly least was the opportunity, honor and priviledge to meet Dr. Ted Maiman–the inventor of the first laser, and his absolutely lovely wife Kathleen of 20 years marriage.

    It was fun to ask Dr. Maiman laser physics questions at our table and watch his face light up as he pondered the question and did some math calculations on a piece of paper (which I kept!).

    Dr. Maiman pulled out one of his pink ruby crystals and we used my 535nm green laser pointer to cause stimulated emission from his crystal–a red beam! He was very excited about doing that.

    To learn more about this living historical legend, and get a copy of his autobiography and the real story of the invention of the first laser, go to his website:

    Lot’s of fun for me to meet and interact with someone who will one day be considered in the same way Edison or Alexander Bell are now thought of. Past rivals still alive today prevent him still from getting the recognition he is due.

    Thanks Paul for this special treat!

    Thanks to all in the VLG for being such gracious hosts!

    Thanks for the kind words, David, Glenn & Bob. It was a GREAT day all around from start to finish! Thanks for making your way to Vancouver to support the VLG. Kudos to Paul Newitt, President of the VLG!

    Seeing each other at the ALD in New Orleans and now the VLG in Vancouver, home of the 2010 Winter Olympics, all within the same month is such a treat. It’s getting to be as much a social event as it is an educational one. I think I will miss you guys until we meet again.

    On the bright side, we have home grown hero Glenn van As, and our new found hero, Ted Maiman to keep us intrigued.

    VLG Laser Convergence 2006 in late April. Mark you calendar.

    Warm regards,

    Hi all,

    Thanks for such kind support of the Vancouver Laser Convergence. It was a great time and although it was a bit of a blur for me I really enjoyed the whole event. I especially enjoyed the excitement and energy that Ted, David, Bob, Ray, Scott and Glenn brought to the event and the incredible flow of the whole day. I wouldn’t have changed a thing.

    I can’t say enough about the wonderful way you all treated Dr. Maiman and what it meant to him and Kathleen. I was so happy that they got as much out of meeting all of you as you did them. I think we were all apart of a magical, historical day and something that I am proud to have had a part in. I had some great feedback from speakers, vendors, attendees and the Maiman’s. I have to say that I was thrilled to hear from multiple sources that we managed to pull off one of the most unbiased meetings regarding lasers they had ever been too, Something VLG has been very proud of promoting for the last few years.

    I am so very glad that everyone had the opportunity to enjoy Vancouver at its best. There is so much to see and do here you could spend a life time keeping busy, hey, some of us do!

    I think Bob’s suggestion that this will become a high-tech dental practice symposium in the future is right on target. The feedback from the exhibitors was fantastic and they all seemed very excited about the potential for this annual event. I couldn’t have asked for a better group of speakers and a better key note speaker to boot! Speaking of which, mark your calendars, the 45th anniversary of the laser is only a few weeks away!

    As for Dr. Maiman’s book’s I still have many copies available, none of which can be found on amazon ;). Now there’s a good story smile.gif

    if anyone is interested come on up to Vancouver and we will set you up. or I could just mail you one.

    Thanks again to all who took part and I hope to see you all again in these parts very soon. If anyone has pictures from the event I would appreciate you email them to me so I can get some over to Ted and Kathleen and up on the web site.

    Anyone read this yet? I haven’t gotten around to it yet.

    Heat diffusion and debris screening in Er:YAG laser ablation of hard

    biological tissues

    B. Majaron1, D. ?Su?ster?ci?c2, M. Luka?c1, U. Skaleri?c2, N. Fund

    A double-threshold behavior of the ablation efficiency was observed in human dentin and enamel with Er:YAG laser pulses longer than approximately 300 ms and 100 ms. Its origin can be explained by a simple analytical model of interplay between heat diffusion and the ablation front dynamics. It predicts the fluence values at which the reduced ablation efficiency and excessive thermal damage can, in general, beexpected, depending on the laser pulse duration and the tissue properties. In the repetitive ablation of dry dental tissues, the reduction of ablation efficiency is amplified by tissue desiccation, and probably masked by other heat-induced transformations, such as carbonization of dentin. In the absence of heat diffusion, the ablation efficiency is found to depend directly on the laser pulse duration. The effect, which is attributed to the back influence of the ablation velocity on the debris screening process, is modeled analytically with satisfactory results..

    I have several Pulsemaster 600 IQ units available for spare parts. I will remove the part from a working unit unless you are interested in the entire unit.
    I do not have any spare footpedals or fibers/tips.

    Hi Albert,
    300ms and 100ms sounds very long pd!
    Generally, I think Erbium lasers are set around 140us to 240us.
    Is it 300us and 100us ?

    Bob,
    Wouldn’t it be correct to say that LANAP will help with areas that would receive bone grafting?

    In what sort of defect? Extraction sites? Why would you graft?

    Janet, no worries about exploding patients on O2.

    Bob,

    I believe Matt means for periodontal defects.

    The answer is yes. The LANAP procedure is for new attachment just like bone grafting.

    Can the periolase help with areas of insufficient attached gingiva or areas that need grafting?

    Hi Al,

    No, not really.

    Some are reporting some corornal rebound of tissue following LANAP, but no one knows how to predict or controll it….

    Bob

    It just seemed unclear on this answer that LANAP could help with periodontal boney defects. I know from the bootcamp that it can help with vertical defect areas. The statement “insufficient attached gingiva or areas that need grafting” was not clear whether the grafting applied to soft tissue only, and your answer seemed to apply to soft tissue only. I think that you were reading “insufficient attached gingiva or areas that need soft tissue grafting”. LANAP will be effective for the boney grafting areas and ineffective for the soft tissue grafting areas is my understanding.

    I just want to make this clear for the people who were wondering. Please correct me if I am mistaken.

    As you all may know, I have the Millennium but what are some of the differences pros’ cons etc. of these three lasers. I’ve been asked this by a few dentists. Some say DEKA is better, some say Lares is cheaper. Just curious. Any opinions.

    No one that I know has ever seen a working DEKA Nd:YAG.

    Their product specifications gives a range of pulse durations (possibly from 50 to 550 usec) that are NOT operator controllable–they are software controlled to what engineers think dentists need based on procedure settings.  A dangerous combination of parameters could be used on patients by unsuspecting dentists.  And they refuse to produce any science to support their parameters–and I’ve been asking for 2 years.

    Lares is cheaper.  Del and I designed the second pulse duration in their laser, but that’s all they’ve got–a short and a long PD.  They didn’t have the technological know-how to give us more than two PDs.

    Neither competitor’s product comes with clinical hands-on training, a proven patented perio protocol that is FDA cleared, a claim for New Attachment from the FDA, the knowledge to debate with all of our clinicians about the clinical aspects of the protocol, 😉   etc.

    Neither of their products comes with a printer, a power meter, 7 unique operator controlable pulse durations, the custom fiber optic to bend 90 degrees to the distal of molars, nor the TrueFlex handpiece, just to name the obvious.

    Neither has science to back up their claims, “We can do what the PerioLase can do”.  And neither has paid us any patent royalties or has a license from MDT to promote and sell their devices to, …”do what Millennium does with LANAP.”

    Hope that helps!

    Thanks for the reply. I will refer my associates to the forum for the answer you have provided better than I would have.
