Summary

One of the most crucial aspects of orthodontic therapy is retention, which is required to prevent orthodontic relapse . There are two main types of retainers, removable retainer which depends on patient compliance to achieve proper results, and fixed retainer which can overcome the problem of patient compliance, but with using it there is higher risk of plaque accumulation and the process of brushing teeth becomes more complex. However, it is not known whether this necessarily leads to worsening of periodontal outcomes . The increasing use of permanent retainers and their requirement for continuous wear highlight the importance of evaluating their impact on the periodontal health but there is conflicting data available right now on how orthodontic retainers affect periodontal diseases
