Orthodontic occlusion and temporary removable retainers

Abstract

Implementing retention at end of orthodontic treatment is not straightforward: it may induce harmful side-effects on occlusion, muscles, joints and posture. To foresee and prevent such risks, exhaustive clinical examination should be performed ahead of the retention phase: history taking, intra- and extra-oral examination, and static and dynamic analysis. The choice of type of retention appliance will result from this appraisal: The practitioner should be rigorous in producing the device (form and choice of material), fitting it (fixity, stabilization), adjusting it (balance), and above all in follow-up. Whatever the selected retention system, regular clinical follow-up is mandatory, to monitor ongoing adaptive balance: teeth, joints, muscles, etc.
