Class II correction with Carriere Motion 3D Appliance and clear aligner therapy

Clear aligner therapy has been shown to be effective in resolving mild to moderate malocclusions, with shorter treatment and less chairtime compared to conventional systems.1 To overcome some of the aligners’ bio­mechanical limitations while still enabling esthetic treatment of more complex clinical conditions, clear aligners can be combined with various types of auxiliaries.2-4 The Carriere Motion 3D Appliance* (CMA) is an intermaxillary Class II corrector introduced by Dr. Luis Carrière in 2004.5 It has become popular over the past decade, thanks to its efficiency and versatility.6-8 As this case shows, it can be effectively used to establish a dental Class I relationship before starting clear aligner therapy.
