    Hi All,

    Interesting read.

    History does repeat itself.

    A person who doesn’t know history is bound to repeat it.

    The Abacus venture that I am familiar with is run out of Hong Kong. I don’t know much about Abacus here in the US. My guess is that it’s a small hedge fund that could either go short or long, or perhaps already have either a short or long position. If the fund has no position, it’s a strange start to doing research as I would assume someone on staff or by contract has some rudimentary understanding of laser physics. If the fund has a long position, the questions are starting at the wrong spot with questionable timing. If the fund is short, they are stuck with a losing position and are grabbing at straws to extricate themselves from a bad position using whatever means available. (there has been a sharp increas in short-interest since Feb and I am guessing the average breakeven price for the shorts is at least 20% lower than where the stock is trading now) Take your pick but I would not take the questions too seriously until more information is provided. Having said that, I do believe a shoot-out would be useful for current-generation systems. The only thing that’s come close to a shoot-out was a report by Stewart Rosenberg that compared cutting of extracted teeth at a convention.

    PS. Being a money manager or an analyst can be a lonely route, sometimes very lonely. The lonely route is the often the right route.

    Glenn, I believe your numbers, also believe Mark Colona’s experience. Still a larger sample size would be more accurate as I think you probably agree. The other pertinent factors are whether complex hand pieces are used in conjunction with the waveguides as I am sure there is some trade off between complexity-usability-durability. It is a tough optimization call I am sure and the engineers are applying their best knowledge. Corning makes the best low loss (low water content) fiber on the market and Hoya and others do make equivalent quality fibers. However, I don’t believe the fiber portions of the waveguide is an important issue.

    Hi All,

    This is really a laser love in forum, isn’t it? Admit it! Don’t be shy.

    Sometimes, I feel we are all too alone in doing what we do in dentistry. Then doing laser dentistry is an even more isolated segment of the profession.

    So to have this forum to share our thoughts, experiences, and feelings is a wonderful haven. A safe sanctuary in the universe of dentistry. We are indeed among friends here!

    Very glad to have met some of the members who attended the CDA Conference. I am very impressed with the knowledge of Bob Gregg, Del McCarthy, Bill Grider and of course the rising star himself, Glenn van As.

    I placed my order for the Delight today, by the way.

    Cheers to all,

    Andrew

    Hi Bob,
    Thanks to you and Glenn, I finally decided to visit and talk on this ite as opposed to being an inactive observer.It’s good to have direct access to people who are experiencing the same cases and answers to the same questions that you are. You continue to be the source of a vast wealth of laser research and principles that are hard to find.By the way, when are those LSU studies going to press and what journal will they appear in? Look foward to seeing you soon.

    Good for you Andrew and welcome to the wonderful world of lasers. They arent a panacea for all but they really make life exciting and interesting.

    If you need anything dont hesitate to call……..

    Great seeing you in Anaheim and sharing a few laughs.

    Howdy Alfred,

    I thought that was you…..Glad you are participating!  

    Thanks for the kind comments.  Ron Schalter deserves all the credit for making this site available and hospitable to ALL laser users,  not just members of an elite group, company, or academy.  And Glenn is an incredible asset to this forum, posting as I told him at CDA “warts and all”!  Look for some of my clinical case posts soon–when I figure out all the details of picture taking, computer downloading, editing, resizing, uploading………

    Prof Yukna received word back from J. Perio that they needed some addition materials in his paper.  He said it was justifiable comments.  But then he decided to submit instead to the International Academy of Dental Research (IADR) and present his paper this June in Sweden.  He felt this was a better venue and more prestigious than J Perio.(???)

    Tom Lee, DDS, MS (prosthodontist) who was the Director of the AEGD program at UCLA when I was faculty member there visited with me at CDA.  He has always been a good friend and supporter.  He was the one who said we needed to get our stuff into mainstream dental journals, not the laser dedicated journals, so the entire profession could access them.  I showed him the histo and told him it was going into IADR, and he was impressed and excited for us.

    On another note, we have submitted Yukna’s histo to FDA for a new 510(k) clearance/claim for “bone regeneration”. We received a letter and preliminary review asking for additional information.  This was a very positive development as the claim is getting thoughtful consideration.  Ray et all has prepared a response to the questions from FDA, and we are hopefull we have answered FDA’s questions…..We’ll know more in a few months.

    Thanks for asking.

    Bob

    Hi Andrew,

    Congratulations on your DELight decision!  I was sure that’s where you were headed in your decision.  That is my choice in erbiums right now.

    You realize, of course, that the DELight was named after DEL McCarthy?  Right?  Del’s never been the same since….enormous ego now, impossible to deal with.  Told Tom Haney he has ruined a good man.:biggrin:

    Sure, it’s a “love-fest” here–for lasers and what they can do for our patients.  From the practical ways they help us with otherwise clinical difficulties, to the incredible post-op results of previous painful procedures, to the spiritual metaphores for light and healing, and a forum to share it all with those who participate in these experiences we have and we share about our patients’ benefit from our committment to such fantastic technology!!  What’s not to LOVE?!

    Welcome to a world that will change your perspective of dentistry and patient care forever in wonderous ways.

    If the internet and this forum had existed 12 years ago, the field would be futher along, and we’d have a lot more active laser users in dentistry.  Things are gonna change for the positive….. This forum is full of those who certainly have invested in that vision. Glad you now have too!

    Glenn,
    After reading your post as well as all the others, I immediately went to calibrate my fiber(Hoya C.B.) I registered in @ 79% which I guess is pretty good for over a year’s time period. To this point the fiber has not been an issue and the laser moves all day.

    Thanks, Glenn & Bob.

    I am looking forward to implementing the Delight into my practice.

    Situations will no doubt arise that will prompt me to ask for help from you guys and others. But at the same time, I feel confident that I have learned much just from reading through all the inputs on the forum. I pick up some pearls almost everytime I come onboard too.

    Regards to all,

    Hey Andrew,
    Congrats on joining us in Erbium heaven! Sorry it’s the Delight…just kidding! I like both the Waterlase and the Delight, but have the Waterlase! You are in for a fun ride! Welcome!

    Thanks, Mark.

    Hope to drop by to see you on May 23 when you are in Vancouver. Looking forward to seeing you and learning more about the numerous procedures that you do with your Waterlase.

    Kindest regards,

    Andrew

    Hi everyone,
    Here is a case with multiple use for the Erbium Laser. This just happens to be my uncle, visiting from Pennsylvania…he gave me a workout!

    Here is the first radiograph, notice decay on #7, and #9. Also the need for retreatment of the endo on #7.

    Next is the retreatment of the endo…
    MVC-156F.jpg

    Then here is the case AFTER I removed the crowns/bridgework…which is about 20 or so years old…he can’t remember. Alot of decay. #7 is supported by a Removable Partial Denture….7-9 were splinted together…

    Here is other photos…occlusal views…
    DSCF0017.jpg
    DSCF0018.jpg

    We went in and did closed crown lengthening, no anesthetic….T-4 tip, 12%water, 9%air, and finished preparing teeth for cast posts…..
    DSCF0024.jpg

    Then we took impressions….the rest to follow next week as I get the case back from the lab. My uncle said he never felt anything, except my “probe” as I measured the sulcus. Never had any problem as I lasered the soft tissue, and did some boney recontouring creating the ferrule. Unfortunately, I am stuck with his partial, and implants are not an option for him right now, with him living so far away…but in the interim, we will use what he has…maybe next year I can get him to stay for a more extended time to do some implants, and such. I will post more as I get the case back as I said earlier.

    Looks nice Mark.

    What was the wattage setting on the Waterlase for the closed crown lengthening procedure?

    Hi Mark,

    Very nice handling of a case where your hands are kind of tied. Will all 3 teeth again be splinted together for the partial support purpose? If so, you might want him to have custom fluoride trays for home use to increase caries resistance.

    Is the last photo after closed crown lengthening and osseous reduction? If so, WOW for the nice tissue appearance.

    Good stuff.
