Abstract
Introduction: Orthodontic retention is the phase of orthodontic treatment which attempts to keep teeth in the corrected positions after active orthodontic treatment. Without a phase of retention there is a tendency for the teeth to return to their initial position which is called "relapse". To ensure retention after the active orthodontic treatment retainers are used. Recently Fiber reinforce composite (FRC) materials have been introduced in orthodontics. In passive applications they can be used as splinting materials. It is thought that due to the good properties of FRC retainers it could be a suitable replacement as splinting material after orthodontics treatment. Objective: The purpose of this retrospective evaluation was to analyze the performance of fiber reinforced composites used in orthodontic retention. Material and method: This study is based on a practice-based evidence collection in a retrospective manner. In 7 patients FRC orthodontic retainers are placed in a private general dental practice setting. All 7 patients were recalled in one visit. In this visit de orthodontic retainers were evaluated from several aspects. Also the periodontal conditions around the retainers were evaluated according to several criteria. With the derived data, descriptive statistics was performed. Results: The results are divided into three groups namely: the quality of FRC retainers, mechanical performance and periodontal conditions. As to the mechanical performance, this study indicates positive results on the criteria on which the FRC retainers are scored. The results are less positive as regards to the quality of FRC retainers because they presented discolorations and slightly rough or pitted surface areas. The periodontal conditions around fiber applied teeth were not different than around natural teeth, but this aspect must be observed in long-term. Conclusion: Further clinical studies are needed to obtain long-term results on the clinical performance and failure types ofFRC retainers.
