With the rapid development of healthcare, especially represented by the rapid development of lasers, oral medicine is also moving towards a new starting point with unprecedented momentum. With the widespread application and promotion of lasers in dentistry, and their increasingly successful application and high social and economic benefits in practical clinical work, more and more industry colleagues highly recognize them. The technology of laser dentistry, represented by “delicate and minimally invasive” techniques, has not only pushed the minimally invasive surgery of the oral cavity to the extreme, but also pushed the treatment experience of the oral cavity to a new level of “comfortable and painless”. Laser dental treatment has become an indispensable tool in modern oral medicine. This article will delve into the core technology, application scenarios, and innovative solutions of RealLight in laser dentistry, taking you on a journey to appreciate the perfect integration of technology and oral health.

 

1、 Principle of Laser Dental Treatment: Precise and Minimally Invasive Light Energy Conversion

Laser dental treatment is based on the principle of “photobiological effect”, which achieves precise energy transfer and biological regulation through the interaction between specific wavelength laser beams and oral tissues. During laser irradiation, specific components in the tissue (such as melanin, hemoglobin, water molecules) selectively absorb photon energy, producing photothermal, photochemical, or optomechanical effects, thereby achieving different therapeutic goals. Compared with traditional methods, laser technology has three core advantages:

◆ Through precise matching of wavelength and tissue absorption characteristics, only the diseased tissue is subjected to “point-to-point” minimally invasive treatment, thereby minimizing damage to surrounding healthy tissue and achieving precise minimally invasive treatment;

◆ Specific wavelengths can instantly kill bacteria, greatly reducing the risk of infection after surgery and achieving efficient sterilization;

◆ Laser can block blood vessels and nerve endings, reduce bleeding and pain, without anesthesia or only requiring local anesthesia, achieving a comfortable and painless experience.

 

2、 Core laser and wavelength: key to customized solutions

In dentistry, different treatment scenarios require matching lasers with specific wavelengths. The following are commonly used types and their functions:

1. Diode laser (808/980nm)

◆ Advantages: Efficient, portable, outstanding cost-effectiveness, suitable for soft tissue treatment and periodontal therapy;

◆ Application scenarios: Gingival removal, periodontal bag disinfection, soft tissue hemostasis, tooth whitening, etc;  

◆ Mechanism of action: Hemoglobin and melanin are efficiently absorbed, rapidly coagulate blood vessels, and kill bacteria.

 

2. Nd: YAG laser (1064nm)

◆ Advantages: Strong penetration of deep tissues, suitable for complex surgery of hard and soft tissues;

◆ Application scenarios: Oral surgery (such as tumor resection), treatment of peri implantitis, bone tissue carving;  

◆ Mechanism of action: Absorption of water and melanin, with both cutting and coagulation functions.

 

3. Erbium laser (Er: YAG 2940nm)

◆ Advantages: The peak wavelength of water absorption causes minimal damage to soft tissues;

◆ Application scenarios: Dental preparation (such as caries removal), periodontal regeneration treatment, gingival aesthetic plastic surgery;

◆ Mechanism of action: Precise removal of diseased tissue and protection of enamel structure through “micro blasting” action.

 

4. CO ₂ laser (10.6 μ m)

◆ Advantages: High efficiency in cutting hard tissues and significant hemostatic effect;

◆ Application scenarios: tooth preparation, bone tissue cutting, oral mucosal surgery;

◆ Mechanism of action: Efficient absorption of water molecules, achieving tissue gasification and cutting.

 

3、 RealLight: Customized “Photodynamic” for Oral Medicine

As an innovative enterprise focused on laser technology research and development, RealLight has always been guided by the clinical needs of oral medicine, and collaborates with industry partners to explore and improve diversified laser application solutions, helping to enhance the diagnosis and treatment experience.

 

1. Wavelength customization: covering all clinical needs

◆ Single wavelength module: 808nm (efficient soft tissue processing), 980nm (deep tissue penetration), Er: YAG (fine hard tissue carving);

◆ Multi wavelength combinations: 808/980nm dual wavelength, 650/808/980nm triple wavelength, etc. These combinations can simultaneously process multiple tissue types through the synergistic effect of different wavelengths, improving surgical efficiency and accuracy, especially suitable for the needs of complex surgeries.

 

2. Packaging flexibility: adaptable to various devices

◆ Compact packaging: integrated design, suitable for handheld laser instruments;

◆ High power packaging: suitable for large dental workstations;

◆ Customized packaging service: supports OEM/ODM, quickly integrates customer needs.

 

RealLight is driven by “technological innovation+scene customization” to help medical institutions build differentiated competitiveness and create better oral health solutions for patients.
