Is it possible to anchor a tooth with photobiomodulation?

Area of Science:

• Orthodontics and Dental Biomaterials
• Biophotonics and Laser Dentistry

Background:

• Orthodontic treatments often require precise control over tooth movement speed.
• Photobiomodulation (PBM) is explored as an adjunctive therapy to modulate bone remodeling and influence orthodontic tooth movement.
• Understanding PBM's effects on bone density and cellular activity is crucial for its clinical application.

Discussion:

• PBM application before orthodontic force may increase bone density, potentially resisting initial tooth movement.
• Applying PBM to specific teeth during force application can accelerate their movement, enabling differential tooth control.
• The proposed protocol involves an 810 nm laser at 0.1W, delivering 4-6J per tooth on root surfaces.

Key Insights:

• PBM can be strategically used to either reduce or accelerate orthodontic tooth movement.
• The timing of PBM application relative to orthodontic force is critical for desired outcomes.
• A standardized protocol using specific laser parameters (810 nm, 0.1W, 4-6J) is suggested for PBM application.

Outlook:

• Further research is needed to optimize PBM protocols for predictable differential tooth movement.
• Investigating the long-term effects of PBM on periodontal tissues and overall treatment stability is essential.
• Clinical trials are required to validate the efficacy and safety of PBM in diverse orthodontic scenarios.
