Unparalleled Ease of Use

Easy-to-use touch screen

The LightWalker incorporates an easy-to–use colour touch-screen, with an adjustable tilt along with 80 customizable pre-settings covering more than 40 different applications.

Weightless OPTOflex® arm (available with LightWalker AT)

Unique to Fotona Laser systems, the LightWalker’s patented OPTOflex® Er:YAG articulated arm transmits a high-power laser beam to the hand-piece, while maintaining the quality of the laser beam to ensure precision and repeatability even at the highest settings.

The OPTOflex® arm is perfectly balanced during use; making hand-pieces completely weightless in your hand. OPTOflex® allows a maximum degree of control and  full range of motion, therefore allowing smooth manoeuvring of the hand-piece and improving treatment precision and ease.

Easy access spray/heated water reservoir

The integrated spray water container means that you don’t have to rely on any water mains outlet, making your laser system exceptionally mobile and hassle-free. The container is handily located at the back of the system for easy access for refilling. In addition, the water is heated to body temperature, avoiding cold sensitivity reactions during procedures.

Wireless foot-switch

LightWalker also has an optional wireless foot-switch for laser activation. This avoids unnecessary tangling and any potential trip hazard.

Built for efficacy and safety

In the LightWalker Dental Laser series, both the Erbium:YAG and the Nd:YAG “gold standard” laser wavelengths are produced by solid crystal lasers that can significantly outperform Diode lasers in terms of both the peak power generated and the range of pulse durations available to choose from.

Fast efficient cutting with unmatched patient comfort

With the advent of Fotona's QSP (Quantum Square Pulse) technology and higher output power, the LightWalker AT S has established new standards for ablation and cutting speed. This accelerated cutting speed provides LightWalker users with the speed and precision demand of a modern dental practice, while simultaneously increasing patient comfort.

Precise tissue surgery with simultaneous disinfection

To complement the superior power and speed detailed above; the homogeneous absorption of the Nd:YAG laser in soft tissue results in controlled tissue vaporization with simultaneous coagulation, for superior healing and disinfection.

Advanced Hand-piece Technology

Titanium Hand-piece Technology – for Unmatched Durability

All of the LightWalker Dental Laser models feature advanced titanium hand-pieces that provide robust durability for constant handling and frequent sterilization.

Lightwalker's tipped and tipless Er:YAG hand-pieces have an integrated air/water spray with adjustable water temperature for additional patient comfort, together with a quick-disconnect system for greater convenience and easier sterilization.

To date, over 15 specialized hand-pieces are compatible with LightWalker systems.

Automatic Hand-piece Detection – for Ease of Use

The LightWalker AT / AT S system comes equipped with two Nd:YAG hand-pieces, providing two different fibre diameters constantly available at your disposal.

In addition, the LightWalker AT Laser system has an automatic hand-piece detection system which knows exactly which hand-piece you have picked up and automatically restores the last-saved parameters for that hand-piece.

X-Runner™ –  for New Treatment Possibilities

The LightWalker AT / AT S is the first Erbium-based dental laser on the market to have digitally controlled hand-piece technology, providing dentists with entirely new treatment possibilities and unmatched levels of precision that have not been seen before in the world of dentistry

Green Pointing Beam – for Improved Visibility

Introduced specifically for Dental Surgeons, this optional feature for LightWalker AT S helps provide improved visibility over standard red-pointing beams when performing oral surgery.

Lightwalker Models Compared

Three models to choose from, according to your budget and clinical needs.

Comparison Chart for the 3 LightWalker models

The AT and DT LightWalker models are equipped with dentistry’s two most effective laser wavelengths; namely, Er:YAG and Nd:YAG for no-compromise dentistry.

Since different oral tissues react in different ways to different laser wavelengths, it is goign to be a clinical preference that you have a choice of laser wavelengths on your dental laser. With the choice of two complementary wavelengths (in terms of their effect on tissues) LightWalker is seen as a “universal” laser. Practically all laser-assisted dental treatments can be performed with either the most highly absorbed Er:YAG laser wavelength or the most homogeneously absorbed Nd:YAG laser wavelength.

The combination of the two optimum wavelengths in one laser system enables Dental Practitioners to perform not only single-wavelength but also dual-wavelength (TwinLight®) treatments. Being able to use both wavelengths in a treatment makes optimum use of the unique laser-tissue interaction characteristics of each wavelength. For example, Nd:YAG laser energy is superior for coagulation and deep disinfection, while Er:YAG is uniquely efficient at ablating hard and soft tissues.

Combined, they can greatly expand the range of treatment possibilities and dramatically improve the outcome of laser assisted treatments.

Treatments

TwinLight Periodontal Treatment

The TwinLight® Periodontal Treatment approach gives general dentists the confidence to treat their patients’ moderate-to-severe periodontal disease the laser way, without scalpels and sutures.

TwinLight® Periodontal Treatment is a minimally invasive periodontal disease therapy incorporating dentistry’s two best laser wavelengths.

Step 1:   Nd:YAG laser removes the diseased epithelial lining and improves access to the root surface.

Step 2:   Er:YAG is used to thoroughly remove calculus from the root surface.

Step 3:   Nd:YAG laser energy is used to coagulate and leave a stable fibrin clot.

The TwinLight® approach enables wavelength optimized treatments for periodontal therapy (WPT™), creating favourable conditions for healing periodontal tissues, by removing the diseased epithelial lining of the periodontal pocket, removing microbial bio-film and calculus from the root surface, sealing the pocket after treatment with a stable fibrin clot..

TwinLight Endodontic Treatment

The Fotona TwinLight® Endodontic Treatment successfully addresses two major disadvantages of traditional chemical-mechanical techniques; namely, the inability to clean and debride anatomically complex root canal systems and the failure to deeply disinfect dentinal walls.

In the TwinLight® treatment, a revolutionary photoacoustic streaming method is employed, as the first step, utilising the power of the Er:YAG laser to generate non-thermal photoacoustic shock waves within the cleaning and debriding solutions introduced in the canal. As a result, the canals and subcanals are left clean and the dentinal tubules are free of a smear layer.

This powerful photon-induced photoacoustic streaming method, available only with Fotona dental lasers, is equally effective for final water rinsing prior to obturation.

Following this, the second step uses the deeply penetrating Nd:YAG laser to decontaminate dentinal walls up to 1000 μm deep.

The high peak-pulse power of the Nd:YAG energy in the Fotona LightWalker laser plays a vital role here as it induces maximum temperature pulsing for eliminating bacteria.

TwinLight Peri-implantitis Treatment

TwinLight® Peri-implantitis Treatment combines dentistry’s two favoured laser wavelengths, Er:YAG and Nd:YAG, to significantly enhance treatment success rates and to shorten healing time.

Initial removal of granulation tissue from the alveolar bone and connective tissue with Er:YAG laser is selective. The bactericidal effect of Er:YAG on the surgical site is highly effective and the implant surface is completely cleaned without chemicals. 

The subsequent Nd:YAG treatment step promotes faster healing by decontaminating and bio-modulating the tissue. Inflammation, swelling, and bleeding of soft-tissue lesions, which may lead to bone loss, can be handled without surgery, and healthy peri-implant tissue assures greater long-term implant success.

Gentle treatment with LightWalker assures that the highly fragile bone surrounding the implant remains intact. 

Because the Er:YAG wavelength with LightWalker is used in a safe mode, there is no danger of thermal damage to the surrounding bone and no significant alterations of the implant surface, as is caused with other lasers. There is no mechanical, chemical or any other means of trauma during the entire treatment.

TwinLight Peri-implantitis treatment

Step 1 - Removal of the soft-granulation tissue and ablation of the infected bone with Er:YAG
Step 2 - Removal of the bacterial bio-film on the implant surfaces with Er:YAG
Step 3 - Bacterial reduction and biostimulation of the bone tissue with Nd:YAG

TouchWhite Tooth Whitening

TouchWhite® patented tooth whitening employs the fact that Er:YAG laser is absorption most strongly in water, which is the major component of aqueous bleaching gels.

This means that no additional absorbing particles are required in the bleaching gels.

More importantly, taking into account thermal burden considerations, the TouchWhite® procedure represents the most effective and least invasive laser-assisted tooth whitening method possible.

Due to its high absorption in the aqueous-based bleaching gels, the laser beam is fully absorbed in the gel and does not penetrate to the hard tissue or the pulp. All of the laser energy is thus effectively used for the heating of the gel. There is no direct heating of the dental tissue and the pulp, as is the case with other laser-assisted whitening methods.

There is also no risk of accidentally damaging the hard dental tissue as the laser fluence of every laser pulse is set to be significantly below the ablation threshold for dental tissues.

As a consequence, the procedure can be performed with a minimal undesirable thermal burden on the tooth, and the tooth whitening speed can be safely increased by 5 – 10 times.

NightLase snoring treatment

The patented NightLase® Treatment is a fast, non-invasive means of increasing the quality of a patient's sleep.

NightLase® lessens the effects of sleep apnea and decreases the amplitude of snoring through the use of gentle, superficial Er:YAG laser light. No anesthesia is used in this treatment.

During NightLase® treatment laser light gently heats the dermal layer, causing tightening of the tissues without damage or adverse effects. It is gentle enough to be used on the sensitive tissue inside the mouth, but strong enough to provide clinically efficacious heating.

NightLase® is easy for any dentist to perform and has a high success rate in producing a positive change in sleep patterns. Research has shown that NightLase® reduces and attenuates snoring and provides an effective, non-invasive technique to lessen the effects of sleep apnea.
