Abstract:
Aim: this study was aiming to evaluate the impact of platelet rich plasma on upper canine rotation after maxillary teeth en-masse retraction.
Material and Methods: Twenty patients with age range 18-25 years were enrolled in this randomized controlled clinical trial over a duration of twelve months. They were classified into two groups; Group I: Control, Group II: Platelet rich plasma (PRP) injection. In both groups extraction of the maxillary first premolars and retraction of the maxillary anterior teeth on two self-drilling miniscrews was done. The six anterior teeth were retracted by Niti coil spring on crimpable hooks placed distal to the upper lateral incisors. The rotation of upper canines was measured from digital models.
Results: The results showed insignificant difference between the two groups regarding upper right and left canine rotation (P>0.05) for all measurements.
Conclusion: The impact of platelet rich plasma injection on upper canine rotation showed no difference after maxillary teeth en-masse retraction.
