Research Abstract

To make the multibracket appliance used in orthodontic treatments more esthetically acceptable, we have been developing transparent composite materials with enough mechanical properties comparable with metal wires. Owing to the support by a Grant-in-Aid for Scientific Research (C), we successfully fabricated PMMA/layered silicate composites with nanoscale reinforcement architecture. The remarkable results obtained through this study encourage us to make them applicable for transparent FRP orthodontic wires.
