ABSTRACT
The orthodontic treatment is, perhaps, in terms of duration, the longest-performed dental procedure. In this fast-paced world any treatment that would consume 1 – 2 years is unwelcome. It is universally accepted that if the duration of the orthodontic treatment is reduced, there will be an increased favorable attitude towards the orthodontic therapy. 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. This review article includes history, biomechanics, indication, contraindication, case selection, treatment planning, surgical techniques and its modifications.
