title: [Orthopedic activators for growth and treatment of Class II malocclusion].
abstract: Activators are functional jaw orthopedic appliances which provide various mandibular position, but always different from habitual positions. Mechanisms and modus operandi of activators explain therapeutic objectives of clinicians. When we analyse different determinants of modus operandi of activators (skeletal, muscular and articular), it is possible to classify these appliances in rigid monobloc appliances, composite or elastic activators and thrusting activators. Many prospective or retrospective clinical studies analyse dentoalveolar or skeletal effects of the activators.
