The role of friction in orthodontics

Mariana Ribeiro PACHECO, Wellington Corrêa JANSEN, Dauro Douglas OLIVEIRA

Introduction: Sliding mechanics is widely used during orthodontic treatment. One of the disadvantages of this mechanics is the friction generated at the bracket/archwire interface, which may reduce the amount of desired orthodontic movement obtained. Due to the application and great acceptance of this type of mechanics, the role of friction in Orthodontics has been of interest for both clinicians and scientists. Objective: Therefore, this article discussed how friction affects orthodontic tooth movement, with an approach to its clinical implications as well as the evolution of dental materials and its properties regarding resistance to sliding.

Keywords: Orthodontics. Orthodontic brackets. Dental materials.
