The joys of a Dual Wavelength Laser

I've had a Lares Powerlase AT for 4 years and I have been extremely happy with my purchase. The device is reliable, requires no maintenance, and works phenomenally well. I also love it because it is an Er:YAG and an Nd:YAG laser all in one unit. Clinically this has some distinct advantages that save time for both the patient and the doctor.

Here is a story from yesterday: A crown prep was being performed on a tooth that had a good sized area of caries on the distal. The area had been filled with an overgrowth of hyperplastic gingival tissue. The area was prepped with a handpiece to ideal form. Next the Er:YAG was used to quickly remove the hyperplastic tissue. Then the Nd:YAG wavelength was selected. The tissue was contoured to an ideal shape and form and the margin was troughed for definition in the impression. Since the Nd:YAG is attracted to dark color, this was all done in a field with hemostasis. Past experience tells me that there will also be minimal post-op discomfort if any at all.

After the laser, a buildup was placed and the prep completed. A beautiful impression was obtained and the temp was fabricated. Total laser treatment time was about 5 minutes. Having both lasers in the same unit made this treatment quick and easy with minimum setup.

Lasers allow us to do amazing things. If you have been thinking about a laser for your practice, I highly encourage you to explore your options.
