Craniofacial 3D Imaging: Transforming Clinical Practice or an Overrated Tool?
Nikolaos Gkantidis
University of Bern
Speaker Bio
Nikolaos Gkantidis has been a full-time Senior Staff Member at the Department of Orthodontics and Dentofacial Orthopedics, University of Bern, Switzerland, since 2016. He earned the title of Venia Docendi (Privatdozent) in 2018 and was promoted to Associate Professor in 2024. Prof. Gkantidis graduated from the Dental School of the Aristotle University of Thessaloniki, Greece (2006), and went on to complete his post-graduate studies in Orthodontics at the University of Athens with honours (2010). From 2010 to 2016, he operated an orthodontic practice in Thessaloniki. Prof. Gkantidis earned his first doctoral degree in 2013 from the University of Bern, where he also worked as a part-time staff member (2012–2016). In 2022, he further expanded his academic qualifications with a Ph.D. from the University of Groningen, Netherlands.With a strong research focus on the development and application of 3D imaging techniques in clinical research, the study of facial aesthetics, and craniofacial morphology, Prof. Gkantidis has published extensively. His contributions have been recognized with various national and international awards and research grants. He also serves as an academic editor for six high-impact journals, including Scientific Reports, Journal of Clinical Medicine, Diagnostics, Biology, PeerJ, and Dentistry Journal.
Learning Objectives
Understand the different 3D imaging modalities used in craniofacial assessment.
Evaluate the benefits and limitations of 3D imaging in clinical practice.
Compare the role of traditional 2D methods versus newer 3D techniques.
Assess practical applications of 3D imaging in complex clinical cases.
Reflect on the future of 3D imaging in transforming patient care and research.
Abstract
Accurate craniofacial morphology assessment is crucial for diagnosis, treatment planning, and outcome evaluation. While 3D imaging technologies offer improved precision and deeper insights into craniofacial structures, their true value compared to traditional methods is sometimes debated. Are they truly transforming clinical practice, or is their impact overstated?
This lecture examines the role of 3D imaging in clinical practice and research, with a focus on key modalities such as extraoral 3D photography, intraoral digital models, and 3D radiographs. We will highlight the advantages of 3D imaging in diagnosing a wide range of outcomes and optimizing treatment decisions. Additionally, we will address common challenges, including technical variability and the practical integration of these tools into everyday practice.
By discussing both the strengths and limitations of 3D imaging, this lecture aims to provide a balanced perspective, helping clinicians assess when and how 3D imaging delivers genuine value compared to established 2D techniques.
3D technologies in orthodontic diagnosis and treatment customization
Alexandra Papadopoulou
University of Geneva
Speaker Bio
Dr Alexandra K. Papadopoulou received her Dental Degree, Specialty Degree in Oral Surgery, Specialty Degree in Orthodontics and PhD from the School of Dentistry, Faculty of Medicine and Health, Aristotle University of Thessaloniki, Greece.
She is currently a Senior Research and Academic staff in the Division of Orthodontics of the University of Geneva, Switzerland while she has also served for seven years as a Senior Lecturer in the Discipline of Orthodontics of the University of Sydney, Australia.
Dr Papadopoulou has supervised several Doctorates in Dentistry and Higher Research Degree projects (Masters and PhDs). She has published numerous research papers in high impact, peer-reviewed journals receiving prizes for her contribution to the specialty’s research. Her main research interests focus on the efficacy of dentofacial orthopaedic treatment, skeletal anchorage devices, 3D diagnosis and treatment planning, the effects of orthodontic interventions on the upper airways and the management of obstructive sleep apnoea (OSA).
Learning Objectives
In this presentation, the theoretical perspectives, and the clinical applications of 3D technologies in orthodontics will be outlined by focusing on the following objectives:
Applications of 3D imaging in the process of orthodontic diagnosis.
Transferability of 3D imaging into the selection of treatment approaches for orthodontic treatment planning.
Assessment of growth-related and orthodontic treatment-related effects.
Upper airway visualization.
Digital planning of ideal biomechanics in goal-oriented orthodontic tooth movement, guided temporary anchorage device-TAD insertion and customization in appliance design.
Abstract
Conventional two-dimensional (2D) imaging and plaster dental models have been the main diagnostic tools used for decades in everyday orthodontic clinical practice. However, these 2D imaging methods often fail to accurately represent all structures of the craniofacial complex or provide exact information for certain pathologies and malformations. Three-dimensional (3D) imaging such as cone-beam computed tomography (CBCT) has broadened the perspectives of orthodontics from the point of diagnosis and subsequently treatment planning, with the advantage of multiple image reconstructions and tissue segmentations. Additionally, merging 3D radiographic images with those of intraoral scans has facilitated the customization of orthodontic appliances.
