After obtaining his Certificate in Orthodontics from the University of Pennsylvania in 1988, Dr. Raffaele Spena completed his specialty in Orthodontics in 2003 at the University of Ferrara. He is the author and reviewer of several publications in Italian and international journals and the co-author of chapter “Nonextraction Treatment” in “Orthodontics – Current principles and techniques”, ed. T. M. Graber & R. M. Vanarsdall, 2000. From 1988 to 2000, he held academic positions at the Universities of Pennsylvania and Parma and since 2003 he is a professor at the University of Ferrara. Dr. Spena is an active member of AIDO, AAO, SIDO, WFO, ASE and EOS and held the presidency of AIDO in 2010 and the Program Chair of ASE in 2015. He served as a member of the Board of the Italian Board of Orthodontics and the European Board of Orthodontics in 2001 and 2008, respectively. He holds a clinical private office in Napoli.
KEYNOTE LECTURE: Periodontally facilitated orthodontics: A different perspective of alveolar corticotomy.
Alveolar decortication is associated to orthodontic treatment with the aim of accelerating tooth movement, reducing treatment time, improving the periodontal status and increasing the stability of the result. While temporary acceleration of tooth movement has been clearly demonstrated, reduction of treatment time is still a discussed topic and is certainly unpredictable and difficult to quantify. Several surgical procedures have been described with the aim of either increasing efficacy or reducing invasiveness of the surgery: not all the corticotomies are the same and their orthodontic benefits may highly differ. Despite the lack of scientific evidence, alveolar corticotomy may have a relevant role in several complex orthodontic treatments and tooth movements. A different view of the biological and biomechanical orthodontic advantages of this surgical adjunct is proposed and indications and limitations are described. Several clinical cases where alveolar corticotomy is associated with miniscrews and simple efficient biomechanical systems will try to elucidate the possible benefits.
