Biomechanics in orthodontics

Biomechanics is the study of mechanics as it affects the biologic systems. It is the application of mechanics to the biology of tooth movement. The physical concepts that form the foundation of orthodontic mechanics are the key in understanding how orthodontic appliances work. The principles are not unique to orthodontics but are basic to the science of static mechanics. With the objective of achieving predictable results based on predetermined treatment goals, the basic mechanics underlying orthodontic appliance activation must be thoroughly understood.
