Research Interests

Spyros Papageorgiou’s main scientific interests encompass biological and mechanical aspects of orthodontic treatment, giving emphasis in improving treatment outcome and reducing treatment duration and side-effects. His focus is on evidence-based orthodontics founded on systematic reviews with conventional meta-analysis or network meta-analysis of randomized clinical trials, clinical trials assessing the comparative effectiveness or adverse effects of different orthodontic treatment modalities, factors influencing the length and outcome of orthodontic treatment, sources of bias in clinical research in orthodontics, optimization of treatment mechanics to enhance their efficiency by investigating clinical scenarios with numerical (finite element) simulations, and the effect of health and systematic diseases on the biology of orthodontic tooth movement.
