This study aimed to evaluate the fracture resistance of the E
glass Fiber Reinforced Composite when used to repair two different
kinds of dental porcelain.
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.
Esthetic orthodontic archwires (fiber reinforced composite archwires) are
considered as the latest addition to orthodontic's world, and the load deflection rate is thought to be the
most important mechanical property of archwires which has strong e
ffect clinically, and this property is
affected by the cross section diameter and the material's type, for these reasons this study aims to
investigate the effect of the material's type and the cross section diameter of orthodontic archwires on the
load deflection rate of fiber reinforced composite(FRC) archwires with a diameter of 0.014 inch and
0.016 inch which are suitable for the leveling and alignment stage, and to compare these new materials
with Nickel titanium(NiTi) archwires .
