The treatment option that
patients are looking for.

Dental phobia is real and for many people can be a barrier to seeking dental treatment. Studies show that as many as 75% of adults in the U.S. experience some degree of dental fear.(1, 2, 3) Drills, needles and numb lips can prevent people from taking a positive, proactive approach to oral health.

Surprising Trends in Laser Usage from Dr. Roger Levin, Chairman and CEO, The Levin Group

A study published by the Roger Levin Group indicates that Waterlase helps attract new patients and increase treatment acceptance of day-to-day restorative cases that can cover the cost of a laser by providing an alternative to drills with injections, for patients who are anxious or fearful.(4)

By reducing the need for anesthetic, multi-quadrant restorations that once required more than one appointment can now be completed in a single visit. And, because a Waterlase MD Turbo allows you to handle a wider variety of procedures, there is less need to refer patients out for treatment, eliminating another source of anxiety for patients.

Now There is a WaterLase System to Suit Any Practice.

BIOLASE now offers three systems with our industry-leading WaterLase all-tissue laser technology: WaterLase MD, the world's most widely used all-tissue laser system; the 2012 WaterLase MDX (available in 300mJ and 450mJ models), the ideal system for pedodontists, periodontists, and endodontists; and the world's most advanced all-tissue laser, the dual-wavelength WaterLase iPlus.

Compare the features and specifications of each system (see the explanations below) and consult with your BIOLASE Territory Manager to decide which is best for your practice.

Understanding Laser Specifications

Every form of electromagnetic energy – from x-rays to visible light to radio waves has its own wavelength, and every wavelength has unique properties. The 2,780nm wavelength is exclusive to BIOLASE WaterLase laser systems. It was developed by BIOLASE for its superior effectiveness on all tissues dentists need to operate on.

Max Output Power
This is how much laser energy the laser engine can pump out within a given time. While power affects cutting speed, it does not directly determine it.

Pulse Energy
The maximum pulse energy, measured in millijoules (mJ), determines a laser system's top cutting speed per pulse. It is equal to the laser's maximum power in Watts (W) divided by the number of pulses per second in Hertz (Hz).

Pulse Rep Rate
The number of times the laser delivers a pulse of cutting energy per second, measured in Hertz (Hz). The higher the pulse rate, the faster the laser will cut. At pulse rates over 30Hz, pulse energy decreases and faster pulse rates may increase patient discomfort when performing a procedures without anesthetic.

Pulse Duration (H–Hard Tissue / S–Soft Tissue)
The length of time the pulse of energy is "on"

Laser Engine
The system's source of laser energy, laser engines – like car engines – deliver different levels of performance. But, also like car engines you pay for greater performance. The ЯR laser engine used in the WaterLase MDX and iPlus laser systems is the most advanced available on any dental laser. The MDX's version is set to run at a lower level than the iPlus'.

Delivers the laser energy, water, air and illumination to the treatment site. For improved ergonomics, lighter and more flexible is better. The WaterLase MDX and iPlus use an ultra-thin, titanium clad fiber.

User Interface
How you control the laser system's many settings to perform procedures. A dashboard lets you adjust each setting individually. A procedure-based graphical user interface "hides" the numbers, automatically adjusting all settings depending on the procedure the clinician selects.

Touchscreen size
The size of the screen increases readability and allows more information to be displayed.

With a dashboard interface users can store favorite settings for frequently performed procedures. The graphical user interface is fully programed for over 50 procedures, and lets users save customized settings.

Built for speed and productivity.

The Waterlase MDX unique, patented combination of a YSGG laser and water spray delivers breakthrough cutting speeds. How fast? Clinicians experience no noticeable difference in speed compared to conventional high-speed drills.

The MDX can perform minimally invasive Class II MO/DO cavity preps in just seconds. It even excels at cutting osseous tissue and it cuts soft tissue faster and with less trauma than soft tissue lasers.

Pays for Itself

With its exceptional versatility, the MDX can quickly pay for itself. By enabling new capabilities such as multi-quadrant dentistry, the MDX brings additional revenue to the practice while reducing the number of patients referred out.

Many procedures can also be performed without anesthetic, so you spend less time waiting to begin working. And of course, any device that reduces the need for anesthetic is also reducing pain and discomfort, something highly attractive to new patients.
