Overview
Discover the UTU multi-wavelength dental diode laser platform combining 4 wavelengths (405nm, 450nm, 650nm and 980nm) plus a 520nm aiming beam. Designed to expand clinical capabilities from soft tissue cutting and hemostasis to oral diagnosis, photobiomodulation (LLLT), light curing and comprehensive therapy-oriented workflows. The UTU platform emphasizes a durable aluminum-magnesium alloy case, intelligent software (AI assistant v3.0), and safety features such as an NFC fiber identification system and a protective lens for the laser aperture.

Clinical applications

• Periodontics
• Endodontics (including root canal disinfection)
• LLLT / Photobiomodulation (biostimulation, pain relief, healing acceleration)
• Aesthetics
• Implant procedures
• Oral surgery
• Pedodontics
• Prosthodontics
• Oral diagnosis (fluorescence-based detection) — NEW
• Dental light curing — NEW

Wavelengths and primary functions

• 405nm (violet): Fluorescence induction for oral diagnosis (detection of lesions, bacterial plaque), oral disinfection and adjunctive endodontic therapy.
• 450nm (blue): High absorption by hemoglobin and pigments — optimized for precise soft tissue cutting/ablation with reduced bleeding and minimized thermal spread.
• 650nm (red/LLLT): Low-level laser therapy — accelerates healing, reduces inflammation and manages acute/chronic pain.
• 980nm (infrared): Preferred for cutting, hemostasis and antibacterial effects; used in many dental procedures and endodontic sterilization.
• 520nm (green) aiming beam: High visibility against tissue to enhance targeting accuracy; advantages include enhanced visibility, tissue penetration visualization, reduced collateral damage and minimal thermal injury when used appropriately.

Advanced wavelength synergy
The platform supports combined emission paths (for example 980nm + 650nm mixed emission) to broaden therapy-oriented options and elevate clinical versatility across procedures.

Design & usability features

• Top-notch chassis: Aluminum-magnesium alloy housing for improved strength, stability and durability.
• NFC fiber identification: Automatic recognition of compatible optical fibers to ensure accessory/equipment consistency and prevent cross-brand interference.
• Protective lens for laser aperture: Protective window between the laser module and aperture to reduce module damage risk from dust/dirt and extend service life.
• New doctor-focused UI: Streamlined user interface tailored for clinicians to reduce unnecessary parameters and simplify operation.
• Soft starter: Optimized software/system startup to reduce failure rates and extend equipment lifespan.
• Standby mode: Automatic screen off/standby when handpiece placed correctly to conserve battery; resumes instantly on pickup.
• Updated AI assistant (software v3.0): Improved intelligent guidance, more humanized assistance and better human-equipment interaction.
• Comfort-focused care: Post-surgery reminders for relaxing/comfort laser therapy to promote wound healing and pain relief.
