Clinical trials: Orthodontic Retainers, open to volunteers
Fixed Orthodontic Retainer, Orthodontic Appliances, Removable
Bacterial Diversity Study Using 16S rRNA Sequencing of Periodontal Samples From Patients With Orthodontic Retainers
After completion of orthodontic treatment, a retention phase is required to prevent relapse of tooth malposition. Fixed retention in the mandibular anterior region is commonly used.
