Abstract
Objective — to evaluate the effectiveness of injectable platelet-rich fibrin (i-PRF) in accelerating orthodontic tooth movement (OTM) and reducing treatment duration.Materials and methods.
This study used a split-mouth randomized clinical trial with 31 patients (14—31 years old, 9 males and 22 females) with Angle Class I malocclusion indicated bilateral maxillary first premolar extraction with a double-blind design. The i-PRF was obtained from each patient‘s blood and then injected into the buccal and palatal areas of the extraction sites right before the canines were retracted. The i-PRF was used on the left side, and physiological saline was used on the right side of the patients with even numbers. On the other hand, the i-PRF was used on the right side for patients with an odd number, whereas physiological saline was used on the left side. After the leveling and alignment phases, the canines were retracted with 150 g of force. Digital models were obtained at five time points: before tooth extraction, in the fourth, eighth, twelfth, and sixteenth week from the beginning of distalization.
Results.
In the current study, the rate of canine tooth movement was higher in the study group (PRF injection) than in the control group at all time points (p<0.001). PRF injection increased orthodontic tooth movement during the early stage (first 2 months). The average acceleration of canine movement in the PRF injection group was 1.21 times. There was no statistically significant difference between the male and female genders.
Conclusion.
i-PRF can be an effective method for accelerating orthodontic movement with minimal invasion, safety, and being autogenous.
