​The Gemini 810 + 980 diode laser is cleared by the FDA for 30 different soft-tissue surgical procedures as well as the treatment of aphthous ulcers and herpetic lesions.

The following is a list of FDA-cleared indications for use of diode soft tissue lasers:

• Excisional and incisional biopsies
• Exposure of unerupted teeth
• Frenectomy
• Frenotomy
• Gingival troughing for crown impression
• Gingivectomy
• Gingivoplasty
• Gingival incision and excision
• Hemostasis and coagulation
• Implant recovery
• Abscess incision and drainage
• Laser removal of diseased, infected, inflamed, and necrosed soft tissue within the periodontal pocket
• Laser soft tissue curettage
• Leukoplakia
• Operculectomy
• Oral papillectomies
• Pulpotomy
• Pulpotomy as an adjunct to root canal therapy
• Reduction of gingival hypertrophy
• Soft tissue crown lengthening
• Sulcular debridement (removal of diseased, infected, inflamed, and necrosed soft tissue in the periodontal pocket to improve clinical indices including gingival index, gingival bleeding index, probe depth, attachment loss, and tooth mobility)
• Treatment of canker sores, herpetic, and aphthous ulcers of the oral mucosa
• Vestibuloplasty

​No; however, the Gemini 810 + 980 diode laser will perform procedures more quickly and smoothly than other diode lasers without causing additional collateral damage. This is due to the laser’s unique 20 watts of super-pulsed power and long thermal relaxation periods. The Gemini 810 + 980 diode laser also offers increased clinical versatility by combining the two most common diode laser wavelengths (810 nm and 980 nm) to maximize both water and melanin absorption.

​Dual wavelength technology combines the optimal melanin absorption of the 810 nm wavelength with the optimal water absorption of the 980 nm wavelength.

​The Gemini 810 + 980 diode laser is really three lasers in one system. It can operate in single-wavelength mode with 810 nm or 980 nm alone, or in dual-wavelength mode which combines the 810 nm and 980 nm wavelengths into a single laser beam. Operating in dual-wavelength mode also allows for the maximum peak power of 20 watts for faster, smoother cutting.

​Surgical diode lasers operate by heating soft tissue molecules to vaporization temperature (100–150º C). The target molecules—hemoglobin, melanin, and water—absorb laser energy at different rates depending on what wavelength is used. The two most common wavelengths found in dental diode lasers are 810 nm and 980 nm. The 810 nm wavelength is absorbed in melanin at a higher rate than 980 nm, and the 980 nm wavelength is absorbed by water at a higher rate than 810 nm. There may be some clinical situations where a single wavelength is preferred over another, but we recommend using the Gemini 810 + 980 diode laser on dual-wavelength mode to maximize absorption in both melanin and water.

​The Gemini 810 + 980 diode laser does not run off continuous wave. It is a super-pulsed diode laser. All other laser and phototherapy technologies utilize either continuous wave or standard pulse, which merely chops the beam. While continuous wave and standard pulsed lasers can be effective, they do not deliver the same the quality, quantity, and depth of penetration of photonic energy as super-pulsed lasers. Super-pulsed lasers can safely deliver optimal amounts of photonic energy without generating excess heat that could compromise safety. Super pulsing allows for deeper penetration than a laser of the same wavelength that is not super pulsed. This is because short pulses allow for quick absorption at the cellular level.

​The following items are included with the purchase of a Gemini 810 + 980 diode laser:

• Laser unit
• Wireless foot pedal (w/2 AA batteries)
• Handpiece
• Single-use pre-initiated tips (x10)
• Safety eyewear (x3)
• Power supply and extension cord
• User manual
• Training voucher
• Laser warning sign

​No, the disposable tips are intended for single-use only and must be disposed of after each patient use. The tips come individually packaged in a box of 25. The tips are available 5 mm and 7 mm lengths and are 400 microns in diameter. The 5 mm tips come pre-initiated and the 7 mm tips are uninitiated.

​Gemini can be powered by external power or by its internal lithium-ion battery. The battery takes 60 minutes to charge when empty and will supply power for 90 minutes of use when full. The foot pedal uses AA batteries.

​No, there are no installation requirements.

​No, all of the items you need to get started are included with the purchase.

Step 1: The User Manual includes a section on service and troubleshooting. Please see page 39.

Step 2: If the issue cannot be resolved using the troubleshooting guide, you can call Ultradent customer service at 800.552.5512 extension 4024.

Step 3: If you require further customer support, the Gemini 810 + 980 diode laser features a unique remote support feature that allows an Ultradent equipment specialist to diagnose the problem remotely when you plug the unit into a computer’s USB port.

The Gemini 810 + 980 diode laser includes a two-year warranty.

If software updates become available in the future, the Gemini 810 + 980 diode laser can be updated remotely without the need to send the laser back to the manufacturer. The process is the same as the process used for remote support.

There are multiple organizations that offer training and certification. We encourage you to find a training course that suits your specific needs. The following are three options of organizations that will provide discounted training to Ultradent customers.

• Advanced Laser Training with Dr. Chris Owens: advancedlasertraining.com
• GLOH Education with Dr. Robert Levine: gloheducation.com
• Academy of Laser Dentistry: laserdentistry.org

​Each state has different regulations for how lasers should be used in practice. These rules change frequently for both dentists and hygienists. We encourage you to consult your state laws when determining your training requirements. Your Ultradent Sales Representative will be able to provide direction on where to find this information.
