Hi Glenn,
I used the irrigating handpiece with cool sterile saline dripping along the 400nm fiber to the tip.
8W on 0.05s/ off 0.05s
Granulation tissue removed circumfrentially, slight contact trying not to blacken the tip of the fiber ( 2 min ).
As I got closer to the implant , the fiber is moved more quickly so as to further avoid any heat building up on the surface.

Dennis,

That is really great. As I recall, one of your concerns in the beginning was that your area and patient base was so small you were worried that the PerioLase package wouldn’t pay for itself. That is a terrific testimonial!!!

One additional consideration on using the Nd:YAG for this procedure is the penetration ability of the 1064 nm wavelength into the dentin to destroy the bacteria without destroying the dentin. This is because of the selectability of absorption in different substraights for this wavelength.

Hello All,
I’ve decided to jump in and buy a Waterlase. What I’m working on now is financing. The lease proposal is to put about &#362000 down, 60 months of payments and then a 10% buyout at the end. I’m in Florida. Does this sound about right?
Regards,
Al B

Hi Ken,

So many variables if we are discussing bone grafting.

Many implants are placed as single stage these days so you do not even get the opportunity to see that scenario before it is restored.

In your case, because the implant is integrated I might wait 4-6 weeks. Honestly, a couple of exposed polished threads wouldn’t bother me at all.

On the other hand, no news is good news when it comes to implants. Implants in my experience that become symptomatic in any way are much more likely to fail.

I have placed a few hundred fixtures so I am no authority on the subject but from the pictures you showed it looks like the cover screw may have loosened slightly and allowed the infection. Cleaning it out is the best thing to do.

Keep us all posted.

Hi Andy,
I’ve not placed as many implants as you’ve done.
I was worried of contaminating the area again if I were to place bone graft. So I opted not to.
I guess it would either be contamination on the cover screw before suturing or as you said, loose screw. It didn’t feel loose when I unscrewed it after degranulation though.
Thanks for your input!

Glen,
Today , for the first time I actually made a mental note of what I saw upon entering a tooth with a diamond ,using my 4x magnification. I actually could see a “microcrack form as soon as the diamond entered the tooth. I now realize that I have seen this often without thinking twice about it.

Now you know why I don’t use a burr. I try SO hard not to crack these teeth anymore. Thanks for sharing Jetsfan!

Sounds normal Al. You can also seek private financing as well. Good luck, and congratulations!

Hi Al,

Congrats on your decision to get involved with laser dentistry.

You are best to consult with your accountant what is the best financing option–lease or purchase. The rate for purchase is often more attractive but you don’t get as much taxable deductibility.

But the overall cost after 60 months is the real determining factor.

Welcome to the forum.

A paper was published in J. Periodontal 2000;71:810-815
Effects of Diode and Nd:yag laser irradiation on Titanium Discs by Romanos, Everts and Nentwig.
Titanium discs were irradiated with 980 at 5.0, 10.0, 15.0W (cw). disc was irrdadiated using a contact handpiece with a 400um fiber held perpendicular to thedisc surface for 5 sec. Surfaces were irradiated by a linear movement of the fiber, with linear areas 3mm apart.
Irradiated areas were compared with control titanium sites which were not lased. Examined under SEM.
It was concluded that the 980 does not damage titanium surfaces.
Author noted that Temp changes on titanium was to be studied.

Hi Dennis,
What is the charge per quadrant with LPT?
Don’t patients come in for 2 visits ( treating one side at each visit)?
I still have to save up for my Periolase!

This is not surprising as at 980nm, the chromophores are hemoglobin, oxy-hemoblobin and water in the tissue. Metal is non absorptive at 980nm. Thereby it is quite safe to use this wavelength around titanium.

Correct me if I am mistaken.

40 yo male presents for crown preparation tooth #30. Profound local anesthesia establised lidocaine/articaine, gross reduction with diamond in electric handpiece, extensive caries excavated with Er:YAG(ConBio DELight) and composite core placed.

An 810 nm diode laser(ConBio DioDent) was used for gingival retraction around the crown margin. A 400 um bare, initiated fiber applied in a contact, hot tip mode at 1.0 Watt and Continuous Wave for approximately 45 seconds.

I was impressed by the clean, bloodless field. Is it better to NOT rinse the treatment area after application of the diode for retraction? Rinsed with water before thinking(duh!!) but did not get any hemorrhage.

Nice photos and treatment, Al.

Still enjoying your Delight I see. Good for you.

How do you like the Diodent?
