Orthodontic forces move patient’s teeth for correction of malocclusion. Various appliances have been used to deliver forces, which then induce biological cascades such as hypoxia, pain sensation, aseptic inflammation, and bone remodeling. Recent advancements in force-mediated orthodontic tooth movement includes biological theorem and engineering principles. We begin to understand the cellular receptors that directly sense forces. Appliances have been evolved by using the computer-aided design and manufacturing and 3D printing for force delivery. It is a perfect opportunity to review current knowledge and clinical outcomes associated with new technologies.
Learning Objectives:
After this session, attendees will be able to:
Explain the current biological principles of orthodontic tooth movement.
Review digital orthodontic technologies including aligners, 3D metal printing, and hybrid therapy.
Weigh the pros and cons of conventional brace-wire, clear aligners, and hybrid systems.
