Fotona LightWalker II · Dual-wavelength dental laser
Er:YAG cuts, ablates, and decontaminates. Nd:YAG coagulates, disinfects, and seals. Combined in TwinLight protocols, they cover periodontal, restorative, aesthetic, and soft-tissue procedures — with the peer-reviewed research and ROI math to back the investment.

How it works
TwinLight® procedures sequence both wavelengths in a single visit. In periodontal therapy, for example, the Er:YAG laser first removes diseased tissue and calculus from inside the gum pocket — then the Nd:YAG laser disinfects the pocket and seals it. No cutting, no sutures.
Er:YAG · 2940nm
Removes decay, diseased tissue, and calculus with minimal heat transfer — often reducing the need for anesthesia and rotary instruments.
Nd:YAG · 1064nm
Follows the Er:YAG step to control bleeding, reduce bacterial load, and seal treated tissue without sutures.

Watch & learn
Real clinical demonstrations, grouped by area of practice.
TwinLight uses two wavelengths in sequence: the Er:YAG laser first removes diseased tissue and calculus from inside the gum pocket, then the Nd:YAG laser disinfects the pocket and seals the tissue. A non-surgical alternative to flap surgery — no cutting, no sutures.
A second, clearer recording of the same TwinLight periodontal protocol.
Side-by-side X-rays from an actual patient case, before treatment and at follow-up after TwinLight periodontal therapy.
With the gum tissue surgically opened, the Er:YAG laser cleans bacteria and diseased tissue directly off the implant surface — the decontamination step in the peri-implantitis protocol.
The same implant decontamination goal performed without opening a surgical flap — for earlier-stage peri-implantitis cases.
The Er:YAG laser reshapes gum tissue (and bone where needed) to expose more natural tooth structure, without a scalpel or sutures.

The research
Published research behind the Er:YAG and Nd:YAG wavelengths used in LightWalker procedures.
Periodontics · RCT
A randomized controlled trial found significantly better improvements in probing depth and clinical attachment level at 2 months when combined Nd:YAG/Er:YAG laser therapy was added to conventional non-surgical treatment, versus conventional treatment alone.
PubMed · PMID 33813638Restorative · Clinical trial
Early clinical trials found Er:YAG laser cavity preparation caused minimal patient discomfort, with the large majority of treated teeth requiring no local anesthesia at all.
PubMed · PMID 9041505Pediatric · Randomized trial
A randomized trial in children comparing Er:YAG laser to a traditional drill found reduced anesthesia use, less pain, and lower anxiety with the laser, and no meaningful difference in treatment success after a year of follow-up.

Questions
The LightWalker II is a dual-wavelength dental laser system from Fotona, combining an Er:YAG laser (2940nm) for cutting, ablating, and decontaminating tissue with an Nd:YAG laser (1064nm) for coagulating, disinfecting, and sealing — in one platform.
TwinLight protocols use both wavelengths in sequence within the same procedure. For periodontal treatment, for example, the Er:YAG laser first removes diseased tissue and calculus from the gum pocket, then the Nd:YAG laser disinfects the pocket and seals the tissue — without cutting or sutures.
Demonstrated procedures span periodontal and implant care (TwinLight perio, implant decontamination), restorative work (cavity prep, crown and veneer removal, extractions), aesthetic treatments (SmoothLase, LipLase), and soft-tissue/comfort procedures (cold sore treatment, SWEEPS-mode endodontic irrigation). See the Procedures library for video demonstrations of each.
No. The studies summarized on this site are third-party, peer-reviewed research on the Er:YAG and Nd:YAG wavelengths used in LightWalker procedures — several conducted on Fotona systems specifically. Individual clinical results vary by practice, patient, and case. Review the full methodology at the source link before relying on any finding.
Fotona's Low Rate financing offers a fixed 6.75% APR with terms from 36 to 84 months. Use the ROI Calculator to estimate a monthly payment against your expected procedure revenue, and to see an illustrative Section 179 first-year tax deduction estimate.
Qualifying equipment placed in service in the current tax year can generally be deducted immediately — up to $1,000,000 under Section 179, with 100% bonus depreciation currently available on any remaining cost above that. This is illustrative only; confirm current limits and eligibility with your tax professional.
