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.
