Various methods have been proposed to accelerate orthodontic tooth movement, including local injection of pro.staglandin; supplementation with vitamin D; stimulation of periodontal tissue remodeling with vibratory forces, pulsed electromagnetic fields, electrical currents, or low-energy laser devices; and surgical procedures such as corticotomy, alveolar distraction osteogenesis, or periodontal distraction. To date, the most complete body of evidence is for "surgery first" techniques, followed by low-level laser application and corticotomy. More comprehensive studies are needed, even for these methods. As Picton demonstrated, bending of the alveolar bone may account for as much as 25% of initial tooth movement.
