Tools of the trade: Gemini 810 + 980 diode laser


soft tissue laserby Dr Luke Cronin, Quality Dental, North Sydney, NSW

This is a dual wavelength soft tissue laser. I’ve been using it for just over 12 months and have had very good results with it.

What’s good about it

I use the Gemini for gingivectomies and laser troughing for my veneer cases. It defines the gums at the time of preparation rather than needing a second stage of gingivectomy. The tips of the laser are illuminated and give great visibility during the procedure.

It’s super-pulsed which means it has a longer pulse of 20 watts at the start, giving the tissue more time to rest. Other lasers are generally continuous at two watts and that can lead to charring and burning of the tissue. The dual wavelength cuts and cauterises beautifully. The 980 nanometer wavelength attracts water and causes cauterisation. The 810 nanometer wavelength attracts blood and does the actual cutting.

There is less pain for the patient with this laser, both during the procedure and post-operatively. It is a far better method than electro-cautery or using the old electrosurge. 

What’s not so good

The consumable cost with the laser is fairly high. The tips are disposable, single use and are rather expensive to purchase.
