SwpmnSpectatorNice case Glenn, looks great! You probably don’t need that blue phosphoric acid etch.
Al
SwpmnSpectatorSounds great, Janet!!!!
On your Class I’s, is the Continuum preparing the enamel at a satisfactory rate? In other words, will it cut through thick enamel fairly rapidly?

PatricioSpectatorAs I am getting used to beginning with 4 or 6 watts I am realizing how quickly a prep can be completed such as a class II. I am wondering what prep design is recommended for the proximal area. I began with more of a vetical tube but soon realized the actual decay va
ries in position and was ending with angles and slants and under cuts when the decay was finally removed. I can see that at 6 watts it is easy to prep the occlusal aspect of the box wider for vision and ease of decay removal but then we are getting back toward the G.V. Black sized preps. What say you?Mark, where are those new spoon excavators when we need them? I tried to put my regular one in a prep today but it was much to large. I also removed some tissue today at .75w with no water. It was slower but I can see I ended with less bleeding and was better able to use .25w to frost the tissue.

2thlaserSpectatorPat,
Funny you should ask! I actually met with the guys today at Amercian Eagle to finish designs, and I used a few new ones today, I loved em! I hope that before Dana Point, I can have some for everyone to see/try.
In class II’s I try hard to tunnel prep when I can, or then use Stu Rosenberg’s suggestion and slot prep. I try to keep the marginal ridge intact as much as possible, from either side of it. The smaller spoons work well in that area too. I am really trying hard to develop a no rotary use on any tooth in my practice, and the spoons help alot in that regard. Although I had a HUGE one this afternoon on #15, it echoed when we talked! and I had to use a round bur on a slow speed it was so undermined. I know we will never get rid of handpieces, at least in our lifetimes, but I try to take every advantage of the laser I can.
On the tissue side, did you get much charring using .75 with no water or air?
Thanks Pat.
Mark
PatricioSpectatorMark,
I did not get any charring at .75w. It was just slow going but clearly less tissue damage and bleeding when I was done. OK I will continue with the conservative preps but will want some of those spoons ASAP.
I see in the paper last night that our biathletes are traveling to Montana to workout in the snow before heading to Europe. Must make for a long winter. Our ski resort is open but only a trace of snow on the ground in town.
Pat
AnonymousSpectatorJust wondering if anyone had a handle on why they are using the air/H20 ratios they are using?
Other than low settings for coagulation do you always keep these 1:1 , if not why?
Why you might want more air than H20 or vice versa?
Any ideas ?
Thanks
AnonymousSpectatorRecently placed a small ad (4×5″) in weekly advertiser with a distribution of 11,000 (my practice is in a town of 2200). Everyday we get calls from new patients requesting to transfer to us or to just begin coming to the dentist. Tuesday I almost fell over when my receptionist said she had received calls from and scheduled 14 new patients just that day. Great problem to have !
Those of you who have had your lasers longer (August for me), how have the surrounding dentists reacted to the lasers and patient transfers?
2thlaserSpectatorPat,
Where are they going? We have World Class skiing right here in Whitefish. No snow in the lower valley yet, but the mountains are getting their fair share. Good for the skiiers, and hunters this time of year. Still warm though, should be in the 50’s today, gosh, could take the day off and play a round of golf! Is this November??
Keep up the great work and posts, the excavators will be here soon!
Mark
2thlaserSpectatorOne thing I can tell is that the higher the water, with the higher the power, the greater the ablation rate and depth. When I cut the rest preps, the lower water with the lower power, gives me MUCH more control on surface cutting speed and smoothness. Same goes when I do crown/veneer preps. Lower water/air, smoother more controlled ablation, and viseversa with higher power, high speed cutting. In addition, if patient sensitivity occurs, dropping air and water increases patient comfort. I have noticed on crown and veneer preps in particular, that when I place margins, I get GREAT shoulders with the controlled cutting at low wattages, i.e. 1.25W 40%air, 30%water. Now, if the Waterlase is cutting with hydrokinetics, it goes without saying that the more water, the more ablation, the less water the less ablation, and Glenn, please don’t wince on that comment! Hopefully this hydrokinetic thing will get resolved. All I know is that the Waterlase does work different with differing water and air levels, and then finding appropriate power wattage levels to achieve the results one is looking for. AND every laser is different. Your Waterlase is different than mine, and you will probably need to tweek your settings for the “feel” and results that work best in your hands. I hope I made some sense here. I am a newbie after all!
Mark
2thlaserSpectatorPS….I always use more air than water, I just seem to like the effect better.

Janet CenturySpectatorAt the course last month we were told that you cannot use nitrous oxide with the lasers. But one of the pedodontists there said he does it all the time. What’s the word on this – and if it’s contraindicated, what’s the rationale? I LOVE nitrous with kids and this seems like an unbeatable combination, but only if it won’t blow up the patients or something worse.
Janet CenturySpectatorIt goes through the enamel “okay”. Sometimes I get impatient and open up more quickly with the high speed, but as long as they don’t feel it, who cares. Did my first class II and III today. Just flew on the clss III and I felt that the II was easier than the I.
Janet
PatricioSpectatorRon,
One year the middle of December!So far one dentist has come over to see the laser and has recently purchased a whitening light like mine. Another dentist has asked if he could see the machine and a third who is involved in programs for the dental societ has asked if I would present something at the meeting. I generally do not attend so do not have much contact with other dentists. Nothing negative so far. We have had several transfers in which seem to be related to the laser.
Pat
PatricioSpectatorJose,
Gracias por su carta e-mail. Mi esposa trabaja em mi officina pero no es una dentista. Mi correo electronico es doc@smileMQT.com e mi website es <a href="http://www.smileMQT.com.

Nosotros viajaramos a Bolivia en mayo or junio. Nosotros gustaran mucho a vistar su ciudad e pais. Nosotros visitado los fos de Igazu en el ano 1995. Gracias por su invitacion. Nosotros estaran planear un viaje en el proximo meses.
Un afectuoso saludo,
Pat
Glenn van AsSpectatorHi folks………due to alot of reasons , not the least of which is burnout, I am posting less these days. Especially on dental town.
The comraderie here and the interest in learning makes me want to continue posting the odd case here and there.
This was a crown prep I did yesterday I think.
The margin was really deep ( it was tough even with the scope to see what was tooth and what was resin) and once I got it on tooth I thought…….yikes not much biological width.
I stopped the oozing with the Argon (green laser) first so I could see what I was doing and then I removed soft tissue and hard tissue in the interproximal area between the molars.
I think next time I will try to reflect a small flap ala Rodger Kurthy but I need to get some smaller blades and microelevators first …….( I am working on that).
It will be neat to try with the scope.
Anyways I used the erbium and ablated the interproximal bone and tissue and then coagulated it with the argon laser and some hemodent and took my impressions today.
I will follow the case for you. in addition, the radiographs of before treatment started and just before today are included. i will include radiographs of it and photographs of it when we insert the crown.
Hope it makes sense, no time for editing them.
Cya
Glenn
