Aligner orthodontics:from basic research to clinical applications. Prevention of cleft lip & palate: vision for the future

Keynote Lecture - Saturday, September 21, 2019

In recent years aligner orthodontics has grown very fast since an increasing number of patients have sought esthetic and comfortable alternative to fixed appliances.The application of an orthodontic force produces a tissue reaction that is the result of the perturbation generated by the orthodontic appliance and the modeling and remodeling of the alveolar bone. Aligners provide intermittent orthodontic forces and despite their spread among the orthodontic community, there are still doubt relating to the bone metabolism induced by this kind of appliances.Researches conducted at the University of Torino, Italy, demonstrated that aligners seem to be capable of inducing the same biological responses described for fixed appliances, at least in the very early stages of the orthodontic treatment. On the basis of this consideration biomechanics of aligner orthodontics should be optimized in order to permit the control of complex movements like the bodily movement of maxillary molars. Results of studies describing the dentoskeletal effects of Class II correction with Invisalign® aligners will be then presented as well as the effects of the attachments and elastics on the quality of the orthodontic tooth movement.
