Repeated Injections of i-PRF for Decreasing Root Resorption After the Orthodontic Treatment.

Mandibular incisor crowding is a frequent issue that prompts many adults to seek orthodontic treatment. The treatment may enhance patients' quality of life, facilitate dental plaque control, and improve the quality of periodontal tissue. However, this treatment is accompanied by several side effects, including resorption of the apical portion of the teeth. Platelet-rich concentrates, such as injectable platelet-rich fibrin, have been shown to have positive effects on both soft- and hard-tissue healing. They may serve as a beneficial self-derived material to prevent this complication.
