Corticotomy – Accelerated Orthodontics. A Case report

Accelerated orthodontics is one of the desired concepts to reduce the treatment duration.It is based on the fact that when bone is surgically stressed, a series of events is initiated causing increased osteoclastogenesis, hence acceleratory phenomenon or periodontically accelerated osteogenic orthodontics.Corticotomy is the procedure of creating perforations or cuts in the cortical bone and extending minimally into the medullary bone.Surgical injury causes transient osteopenia in alveolar bone.This reduces the biomechanical resistance to tooth movement and enables faster tooth movement through trabecular bone.Periodontally accelerated osteogenic orthodontics (PAOO) technique is a combination of a selective decortication-facilitated orthodontic technique and alveolar augmentation.Based on the concept, following case report showed the application of PAOO in anterior space closure.
