The Effect of Platelet-rich Plasma on the Rate and Type of Orthodontic Tooth Movement

Summary

This study aims to assess the effect of PRP on the rate and type of OTM during en-masse frictionless retraction of maxillary anterior teeth using a segmental arch technique. Thirty adult patients exhibiting class II division 1 malocclusion requiring upper first premolar extractions followed by en-masse retraction will participate in the study. They will be randomly and equally distributed into the PRP group (G1) and the control group (G2). The injection of PRP will be performed pre-retraction. The rate of orthodontic tooth movement will be assessed clinically by measuring the extraction space with a digital caliper. The cephalometric radiographs will evaluate the type of OTM at the beginning of en-masse retraction (T0) and at the middle of en-masse retraction (T1).
