Abstract
Although the surgical-assisted accelerated orthodontic tooth movement has been proved to be the most effective one currently, its disadvantages are it is a bone surgery, and it causes loss of alveolar bone that undermines the periodontal support of the target teeth. The submucosal injection of platelet rich plasma (PRP) is a technique developed for accelerating orthodontic tooth movement by simulating the effects of bone insult without surgery and loss of alveolar bone. We have revealed clinically that submucosal injection of PRP accelerated the mandibular or maxillary alignment 1.7 folds faster in average, and the acceleration was dose-dependent when the PRP fold (platelet count in PRP/platelet count in blood) was en masse anterior retraction decreased 71–77% of alveolar bone loss, and this was dose-dependent. The pressure side of en masse anterior retraction had no alveolar bone loss when the PRP fold was higher than 11.0. In conclusion, the optimal PRP fold for the best performance in acceleration of orthodontic tooth movement and preservation of the pressure side alveolar bone is 11.0–12.5.Keywords
