Hi Andy,

By “deep anatomy” I mean that I don’t want any secondary or tertiary occlusal anatomy that makes them look pretty, but are going to become interferences sooner or later.

Kind of hard to describe in words, but I want the incline planes to be concave versus convex to better accept the opposing tooth’s working cusp.

I want my contacts in real tooth structure if at all possible, or in the proper cusp tip position, and little in the central fossa on seating.

Glenn,

Nice job!

You even covered yourself from criticism from the periodontists by showing that you “sounded the bone” and established your safe removal of soft tissue while preserving the biologic width.

Par excellance!!

Bob

what do you think of placing topical anesthetic on pulp chamber and then using laser at low settings?

Andrew: I have a bias. Ron handles his bias with professionalism and honesty. He has an integrity not found often and I admire him for how much he has learned. He knows that I have many times congratulated him for his persistent pursuit of knowledge and science. He is to be congratulated not only for the development of this fine web site but for his insistence at learning how to use his lasers to the best of his ability.

I will say that both the Continuum and Biolase are fine products and Jeff Cranska knows the Opusdent and can chip in on that one.

Again as you know I am always available if you should want to find out more about the Continuum. If you want to find out more about the Biolase , spend half a day with Randy Narayan.

ASI,
I’ve been a soft tissue Nd:YAG user going on 4 years, I purchased an OpusDuo Erbium at the ADA meeting in New Orleans.
The unit has touchscreen computer controls, a swivel handpiece w/ saphire tips (1000 down to 200 microns) and a foot control that allows you to cut down power without resetting the screen.
I’m still learning uses for the Erbium, I’ve only had it for a month. But no problems with operations or controls.
The handpiece and variable foot control sold me on this brand new machine.
I trained with one of classmates from 20+years ago, he had the older Opus Erbium (He use to be a Continuum user, but switched). He’s jealous of my new machine.
He presented a case at the ALD meeting last week in Florida.
Opus is another player in the hard tissue laser market.

Hi all,

Just reviewed some results from an university industrial affliates program, this time from simulations. Simulations (boundary shock layer model) suggest that the volume ablated (dry ablation of semiconductor material) is proportional to the number of pulses with the radiation flux below the plasma formation threshold which seems consistent with theory. This result is as expected, I think.

Now the question is why Fried et al’s results (“Mechanism of Water Augmentation” Lasers in Surgery and Medicine v31, 2002) show that ablated volume for the water film case is 135X that of the dry case, both after 5 pulses and same fluence. I would have expected based on theory and simulations that the wet ablation case would result only in 5X the volume ablated assuming that the water’s role is maintain a clean and unheated surface for the next 4 pulses. The measurements by Fried were done at 20-30 J/cm2 which is supposedly just below the plasma formation threshold.

Ron,
Sending you pdf pages of the paper now. Let me know if they don’t make it. Best.
