Outline of Final Research Achievements |
We have been developing transparent composite materials with enough properties such as mechanical properties and so forth comparable with metal orthodontic wires to make the multibracket appliance which is used in orthodontic treatments more esthetically acceptable. We have taken particular note of montmorillonite (MMT), one of the representative layered silicates, as a reinforcing material. Owing to the support by JSPS KAKENHI [Grant-in-Aid for Scientific Research (C)] Grant Number 24593070, we successfully fabricated both poly(methyl methacrylate) (PMMA)/silanized organically modified MMT (s-OMMT) composites and poly(L-lactic acid) (PLLA)/s-OMMT composites with nanoscale reinforcement architecture. The remarkable results obtained through this study encourage us to make them applicable for transparent fiber reinforced plastic (FRP) orthodontic wires.
