Summary
Photobiomodulation (PBM) therapy, when combined with orthodontic force, significantly accelerates maxillary tooth movement and extraction space closure by 40%. This pilot study suggests PBM can reduce orthodontic treatment time.
Area of Science:
- Orthodontics
- Biotechnology
- Periodontology
Background:
- Photobiomodulation (PBM) stimulates periodontal ligament cells, aiding bone remodeling.
- PBM synergizes with orthodontic forces to potentially accelerate tooth movement and shorten treatment duration.
Purpose of the Study:
- To compare the monthly rate of maxillary en-masse extraction-space closure over five months.
- To evaluate the efficacy of PBM combined with standard orthodontic force versus standard force alone.
Main Methods:
- A randomized, parallel-arm, single-blinded pilot study with control and PBM groups.
- Standard orthodontic force (300g NiTi coil spring) applied after first bicuspid extraction.
- PBM group received 810 nm diode laser irradiation four times monthly to anterior teeth.
Main Results:
- The PBM group demonstrated a higher monthly rate of space closure (1.09mm/month) compared to the control group (0.7mm/month).
- Tooth movement was 40% faster in patients receiving PBM.
- The difference in monthly space closure rates was statistically significant (p<0.05).
Conclusions:
- PBM, when added to orthodontic force, is associated with an increased monthly rate of extraction space closure.
- The PBM protocol and methodology show promise for larger trials investigating accelerated tooth movement and reduced treatment times.
