Background- Shorter duration of orthodontic treatment is the need for hour in current practice for the orthodontists and the patients. The submucosal injection of platelet rich plasma (PRP) is a technique developed for accelerating the orthodontic tooth movement by stimulating the effects of bone insult without surgery and alveolar bone loss.
Aim-To assess and compare the rate of en-masse retraction between PRP induced and conventional retraction methods.
Materials and method-The sample size comprised of 10 patients requiring first premolar extractions as part of fixed orthodontic treatment. The split mouth design study was done where in one side retraction was carried out with submucosal injection of PRP which is the experimental side and on the other side conventional retraction was done which is control side using active tie back measured with dontrix gauge of a constant force of 200gm was applied.
Result-The results of the study showed that space closure was faster at the experimental side where PRP was given unlike control side.
Conclusion- Comparison of rate of retraction between control side and experimental side showed that PRP assisted en-masse retraction was faster than conventional retraction.
