< Meet your success in Class II treatment with Invisalign >
- Abstract: As the proverb says “Prevention is better than cure” this should be applied to orthodontics in order to reduce the severity of the future malocclusion and and to provide an early correction of the skeletal abnormality. Orthodontics as a branch is more concerned with facial growth, development of dentition, and occlusion. Aligners were not able in correcting dentoskeletal anomalies since few months ago, when Align Technology (San José, CA, USA) introduced the Mandibular Advancement feature. Functional appliances are widely/used in orthodontics for skeletal Class II correction, i.e., advancement of the mandible and the same principles of well known functional appliance (Twin Block) were applied to aligners in order to intercept class II malocclusione related to mandibular deficiency. Preliminary result related to the treatment of growing patients will be presented.
The distalization of maxillary molars is frequently required in class II non-extraction patients. Resolving class II molar relationships by distalizing maxillary molars may be indicated for patients with minor skeletal discrepancies. The upper molars can be distalized by means of extra or intraoral forces. In recent years, several techniques have been developed to reduce the dependence on patient compliance, such as intraoral appliances with and without skeletal anchorage. However, even these devices can produce undesirable tipping of the maxillary molars and/or loss of anterior anchorage during distalization . In the last decades, increasing numbers of adult patients have sought orthodontic treatment and expressed a desire for esthetic and comfortable alternatives to conventional fixed appliances. Invisalign is an orthodontic system that has been introduced to answer this request. Standardized protocols have been developed in order to obtain predictable results with this kind of approach.
Invisalign aligners: from basic research to clinical application
- 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.
The effects of the aligners are not limited to teeth only: the occlusal splint effect could be very useful during orthodontic treatment of patients suffering from sleep bruxism. Results from a research on this topic will be discussed.
Dr. Castroflorio obtained his DDS Degree from the University of Torino, Italy, in 1998; In 2001 he was certified as a Specialist in Orthodontics summa cum laude from the same University. In 2007 he obtained his PhD in Human Morphology from the University of Milan, Italy. In 2009 he completed a postgraduate course in Orofacial Pain at the University of New Jersey, USA.
He is a researcher and aggregate Professor of the Chair of Orthodontics and of the Specialization School of Orthodontics of the Dental School of the University of Torino, Torino, Italy. Since 2019 is the educational and clinical coordinator of the Specialization School in Orthodontics of the University of Torino. Research interests are focused on the biology of orthodontic tooth movement, aligner orthodontics predictability, orthodontic materials, sleep and awake bruxism.
In the private setting, and together with dr. Garino, he held an educational program focused on aligner orthodontics since 2014.
He is author or co-author of more than 100 publications on peer-review journals, national dental journals and of chapters of books, and member of the Editorial Board of the Journal of Aligner Orthodontics edited by Quintessence.
Active member of the Italian Society of Orthodontics (SIDO), member of the European Orthodontic Society (EOS), International member of the American Association of Orthodontists (AAO) and fellow of the World Federation of Orthodontists (WFO).
He is a founding member and board member of the European Aligner Society
His private practice is in Torino, Italy.
