The aim of this study was to compare fiber reinforced composite with wired retainers in terms of assessing the rate bond failure and plaque accumalation . The clinical study was conducted on 20 patients have completed their orthodontic treatment ,the patients have been devided into two groups , each group of 10 samples. The first group of patients had quartz fiber-reinforced composite retainers and the second group had traditional retainers. Then we monitored patients every two months for a year. In each review we were assessing if a retainer in its place or not, and we used disks to assess the amount of plaque accumalation. Wilcoxon test has been used to study the statistical significance differences in bond failure rate and plaque accumalation.
