Biomaterials in Orthodontics

Orthodontics similar to other fields in dentistry is in constant need for research and improvement in the biomaterials used. Indeed the field of orthodontic materials has vastly expanded in the recent decades with the fabrication of new archwire materials new brackets materials and systems as well as the introduction of clear aligners. This topic will focus on the materials used for manufacturing the orthodontic brackets archwires and clear aligners. The biomaterials used in the oral cavity should possess certain qualities. It should be non-toxic possess reasonable strength hydrolytic stability high purity and sterilizability. It should also possess reproducible quality and be resistant to tarnish and corrosion. Some of the biomaterials used by an orthodontist are brackets arch wires bands elastics adhesives and etchants cements impression materials and micro implants.Materials used in an orthodontic office to apply forces to move teeth include archwire loops coil springs latex elastics and synthetic elastomers.
