Effectiveness of low-level laser therapy in accelerating orthodontic tooth movement: a literature review

Abstract

Low-level laser therapy (LLLT) emerges as a promising approach in Orthodontics, enhancing tooth movement through photobiomodulation by stimulating cellular activity and modulating inflammatory mediators. Stemming from therapeutic light applications, it employs low-power lasers, such as diode lasers, to promote tissue regeneration, reduce inflammation, and boost bone remodeling by activating osteoblasts and osteoclasts. Studies suggest its potential to shorten orthodontic treatment duration, yet the lack of standardized clinical parameters hinders its widespread use. Compared to the VPro5™️, which relies on microvibrations and offers convenience, LLLT provides more robust evidence, though both require further validation. Thus, LLLT stands as a valuable adjunctive tool, necessitating additional research for full clinical integration.
