The Research Progress of Platelet-Rich Fibrin Applications in the Orthodontic Treatment

Either the alveolar bone defects or the severe absorbed alveolar bone led by the teeth extraction could have an effect on the orthodontic teeth movement. Guided bone generation technique has supplied a new method for the above clinical difficulty. Platelet-Rich Fibrin has been reported in the orthodontics and clinical researches because of its obvious osteogenic property. This paper was to describe the newly applications of Platelet-Rich Fibrin in orthodontic clinic. In the orthodontic clinic, the alveolar bone defects or the height and the decreased width of alveolar bone always occurred due to the common reasons such as tumor, inflammation, the early loss of teeth, extraction or cleft lip and palate, which would have negative effect on the orthodontic teeth movement. For example, the teeth would not move or have a lot of difficulties in moving, the roots of teeth could be absorbed and the alveolar bone around the teeth would be resorbed 1. The above complications would jeopardize stability of the orthodontic treatment results. Nowadays, the development of Guided Bone Regeneration offered a new method to solve the above mentioned difficulties. Platelet-Rich Fibrin has been more noticed in the bone reconstruction because of its obvious osteoinducivity and osteoconductivity properties. At present, there are many studies about Platelet-Rich Fibrin used in the orthodontic fundamental researches and clinical application. This paper was to describe the newly applications of Platelet-Rich Fibrin in orthodontic clinic.
