Periodontally accelerated osteogenic orthodontic an orthodontic periodontal interface: A review

Periodontally accelerated osteogenic orthodontics (PAOO) or Wilckodontics is a clinical procedure that combines selective alveolar corticotomy, particulate bone grafting and the application of orthodontic forces. Wilckodontics has solved the dilemma of rapid orthodontic movement by exploiting the dynamics of bone physiology and redirecting the emphasis in tooth movement to the manner in which the supporting bone responds to accelerate the tooth movement the orthodontists and the periodontists together have worked out a success formula which is termed Periodontally Accelerated Osteogenic Orthodontics (PAOO) or wilckodontics. Theoretically this procedure is based on the healing property of bone known as (RAP) regional acceleratory phenomenon. This procedure involves the surgical demineralization of the cortical bone (corticotomy) thereby decreasing the resistance offered by the cortical bone of the teeth to the orthodontic force applied and use of particulate bone grafting. This method not only enhances the width of the alveolar bone but also decreases the duration of the treatment and chances of apical root resoption. It also increases the stability of the treatment by reducing the chances of relapse. A proper case selection, careful surgical procedure and accurate orthodontic movements are important for the success of wilckodontics orthodontic forces.
