Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Different types of retainers have been used to assure the stability of orthodontic treatment. The aim of this study is clinical and radiographic comparison and evaluation of two common types of lingual fixed retainers on the health of periodontium.

The participants in this study will be examined both clinically and radiographically just after the completion of orthodontic treatment and after a 6-month-period.

The results of the study will be analyzed with Mann-whitney and independent t-test.
