Resin Composites Reinforced by Nanoscaled Fibers or Tubes for Dental Regeneration

Figure 3

Diagram of reinforcement mechanism of dental composites. (a) Extremely hard nanofibers or tubes, (b) extremely hard nanofibers/tubes highly aligned along some orientation uniformly in the dental composites, and (c) when dental composite subjected to powerful pressure, nanofibers, or tubes acts as a bridge across the microcrack which impedes the growth of crack, and then dental composites will be reinforced.
