Orthodontic Retention
Survival Rate of Two Types of Multistranded Fixed Retainers
1. Why is this study being done? After orthodontic treatment (such as braces), teeth can move back toward their original positions. To prevent this, orthodontists use retainers during the retention phase of treatment.
