Acceleration of Tooth Movement Using PRP and Photobiomodulation With Clear Aligners

26. august 2026 opdateret af: Arij Lutf Abdulrhman Abdul Majid, Sana'a University

Evaluation and Comparison of Acceleration of Tooth Movement Using Platelet-Rich Plasma (PRP) and Photobiomodulation (PBM) With Clear Orthodontic Appliances (Aligners): A Randomized Controlled Clinical Trial

This study compares the effectiveness of two adjunct therapies- photobiomodulation (low-level laser therapy) (PBM) and localized platelet-rich plasma (PRP) injections in accelerating orthodontic tooth movement. Participants receiving clear aligner therapy will be randomly assigned to one of three groups: clear aligners with PBM, clear aligners with PRP, or clear aligners alone (control group). The goal is to evaluate the efficiency, tooth movement tracking and safety.

Detaljeret beskrivelse

This randomized controlled clinical trial evaluates the acceleration orthodontic tooth movement using two adjunct biological stimulation modalities in patients under going clear aligners therapy participant are allocated into three groups:

  1. Clear aligner + photobiomodulation (PBM) : receives low-level laser therapy at specific intervals to stimulate cellular turnover and bone remodeling
  2. Clear aligner +platelet-rich plasma (PRP) :receives localized autologous injections in the target tooth movement area to facilitate biological response
  3. Clear aligners alone: (control group )receiving standard clear aligners treatment without additional interventions.

Outcomes will be evaluated periodically using digital intra-oral scanning to measure tracking, accuracy, rate of orthodontic tooth movement, and soft tissue - periodontal health throughout the active treatment period.
