2019 Annual Session Conference

Treatment Effects Produced by the Carriere Motion Appliance in Class II Patients

May 4, 2019 9:10am ‐ May 4, 2019 9:40am


The Carriere Motion Appliance can be used effectively and efficiently in the management of Class II patients at various stages of maturation. This treatment requires maximum compliance, with the patient wearing heavy intermaxillary elastics for 5-8 months followed by either fixed appliances or clear aligner therapy. The results of a retrospective study of the treatment effects produced by the Carriere appliance followed by fixed appliances in adolescent Class II patients will be discussed. The primary effects of treatment are a distilization of the maxillary posterior dentition and a clockwise rotation of the occlusal plane during the first phase of treatment that rebounds partially during the second phase. The effects on mandibular length generally are slight and vary widely among patients.

Learning Objectives:

  • Identify the basic components of the Carriere Motion appliance and how it is used clinically.
  • Evaluate the skeletal and dentoalveolar effects produced by the Carriere Motion appliance.
  • Discuss the force levels produced by various orthodontic elastics used routinely in clinical practice.
