Orthodontic fixed retainer, fiber-reinforced-composite retainer, composite-wire retainer
Brief summary
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.
Interventions
DEVICEFiber-reinforced-composite retainer
this type of retainer is placed on the lingual surface of teeth from canine to canine just before the completion of orthodontic treatment
DEVICEComposite-wire retainer
this type of retainer is placed on the lingual surface of teeth from canine to canine just before the completion of orthodontic treatment to prevent treatment relapse
