Seq# 12 - From Basic to Contemporary Methods and Techniques in Orthodontics

Orthodontic tooth movement (OTM) is a unique model that includes the induction of aseptic inflammation and its resolution. Prolonged, low-force mechanical loading of the teeth results with areas of tension (away from the movement) and pressure (towards the movement) in the alveolar bone. The cellular and molecular biology cascades lead to dynamic anabolic and catabolic processes enabling bone changes during OTM. OTM is primarily a periodontal ligament (PDL) phenomenon, since the bone response is mediated by tightly regulated immune reaction series through cytokine and chemokine arrays within the PDL structure. New insight into OTM and bone biology along with patients demand has elucidated newer technologies in orthodontics based on cellular and molecular behavior. The symposium will focus on basic science evidence alongside clinical examples of accelerated tooth movement technologies using low intensity pulsed ultrasound (LIPUS) and extracorporeal shockwave therapy (ESWT). Minimizing orthodontically induced tooth root resorption and enhancing tooth movement will be exemplified and discussed. The ability to move teeth through periodontal regenerated tissues will be presented as compared to OTM through normal “healthy” tissues. Finally, more recent research investigating the effects of increased body mass index on the periodontal inflammatory response and orthodontic tooth movement will be presented.

Learning Objectives:

  • Provision of the biological and social aspects of accelerated tooth movement based on the comprehensive biological principles of OTM and the consequent side effects.
  • Introduction of the accelerated tooth movement technologies evolved nowadays: LIPUS and ESWT - based on the cellular and molecular biology cascades' modifications.
  • Alteration in the habits of the learner regarding OTM through periodontal regenerated bony defects compared normal bony area discussing its predictability and optimization.
