Overview

LumiSmile 2940nm Er:YAG Dental Water Laser is a professional dental laser system designed for minimally invasive hard and soft tissue procedures.

Using a 2940nm Er:YAG wavelength, the laser energy is highly absorbed by water and hydroxyapatite, which are key components of oral soft tissue, teeth and bone. This makes the system suitable for precise dental tissue ablation, disinfection and minimally invasive treatment across a wide range of dental applications.

LumiSmile is designed for dental clinics that want to upgrade from traditional mechanical treatment methods to laser-assisted dentistry, while maintaining practical equipment cost, flexible clinical use and reasonable consumable management.

Key Technology: 2940nm Er:YAG Dental Water Laser

Er:YAG stands for Erbium-doped Yttrium Aluminum Garnet. It is a solid-state laser operating at 2.94μm / 2940nm in the mid-infrared spectrum.

The 2940nm wavelength is close to the peak absorption of water and is also well absorbed by hydroxyapatite. Because dental tissues contain water, the laser energy can interact efficiently with the target tissue and create a controlled micro-ablation effect.

This is why Er:YAG technology is often described as a dental water laser. The laser energy works through water absorption in the target area, helping dentists perform precise hard tissue and soft tissue treatments with reduced vibration and less mechanical trauma compared with conventional rotary instruments.

Depending on the treatment indication, tip selection and parameter settings, the system may be used in contact or non-contact techniques.

Main Clinical Applications
Restorative Dentistry

LumiSmile supports precise and selective ablation of carious lesions while helping preserve healthy dental tissue.

It may be used for:

Caries treatment
Enamel and dentin ablation
Cavity preparation
Pit and fissure treatment
Dentin decontamination
Minimally invasive restorative procedures

The system helps reduce vibration, micro-cracks and carbonization compared with traditional mechanical preparation when used properly.

Implantology

LumiSmile can support selected implant-related procedures, including soft tissue management and implant surface decontamination.

Potential applications include:

Second-stage implant surgery
Implant uncovering
Peri-implantitis treatment support
Implant surface decontamination
Bone ablation
Sub-ablative disinfection

The product material highlights its use for implant decontamination without damaging the implant surface when proper settings and techniques are applied.
