Athina Chatzigianni


Dr. Athina Chatzigianni graduated with honors from the Dental School of the Aristotle University of Thessaloniki (AUTh), Greece in 2002 (first in the rank). She has served as Research Fellow at the Department of Orthodontics, Radbound University, Nijmegen, Netherlands, and completed her Master thesis and specialty training in Orthodontics at the University of Athens, Greece (2007). She received her Doctorate Degree from the University of Bonn, Germany and continued as a post-doctoral researcher in AUTh. Since 2012 she works as a clinical instructor and research associate at the Department of Orthodontics of AUTh.

She has received several distinctions such as the Award from the Dental Association of Thessaloniki for the highest graduation degree (2002), the WJ Houston Poster Award for the best research of young researchers (EOS Congress, Helsinki, 2009), the Excellence Scholarship for Postdoctoral Research Fellows by the Research Committee of AUTh (2012), the 2nd Poster Prize (MOIP Congress, Cyprus, 2016) and others.

She is a member of the Board of Trustees of the Orthodontic Society of Northern Greece and General Secretary of the Balkan Association of Orthodontic Specialists. She is also a member of other orthodontic societies worldwide.

She has published a number of scientific papers and serves as reviewer in orthodontic journals. Her clinical and research interests include mini-implants, lingual orthodontics, 3D imaging, cleft lip and palate, craniofacial orthodontics and geometric morphometrics.

INVITED LECTURE: 3D shape analysis in Orthodontics

Two-dimensional (2D) cephalometric radiography has been broadly applied in orthodontics, by means of linear and angular variables. Recently, three-dimensional (3D) data obtained from cone-beam computed tomography (CBCT) has redesigned cephalometric diagnosis and treatment planning. However, some major limitations are still to consider. In this lecture a combination of 3D data with geometric morphometric methods will be presented in an attempt to provide new concepts in Orthodontics. The trajectory of the application of Geometric Morphometrics from the Science of Paleontology to the Orthodontic Science will be discussed. Finally, new 3D templates created by the author will be introduced and a 3D analysis of the shape and form of different parts of the craniofacial complex will be proposed. This analysis will show that important parts of the craniofacial area could be better described, while a wide 3D shape variation accumulated on specific areas among individuals is present. Moreover, a strong association among parts of the 3D craniofacial complex is evident, which implies the possible role of genetics, epigenetics, function and growth on their adjunct morphology. Based on the assessment of the results, 3D geometric morphometric methods seem to be a promising alternative to conventional 2D or 3D cephalometry in describing craniofacial surfaces and relationships in the future.
