Research Interests

  • Biomechanical and histological aspects of temporary anchorage devices (TADs)
  • Clinical outcome of cases treated with TADs
  • Pain control during orthodontic tooth movement
  • The role of central and peripheral nervous systems in orthodontic treatment
  • Effect of neuronal substances on osteogenic cells during tooth movement
  • The use of digital models and scanners in orthodontic treatment
  • Evaluation of orthodontic treatment outcome using quantitative occlusal indices in various techniques

Clinical Interests
