Why the NiTi as the raw material of bristles
NiTi has the best mechanical property for debridement of titanium based dental implant surface.
NiTi is 3 times more flexible than titanium.NiTi has similar hardness with titanium.NiTi can debride the implant surface with less damage.

- We can say that the NiTi bristle could be more effective than the titanium bristle for the debridement of titanium based dental implant surface.
- Stainless steel is very hard material and it has less flexibility comparing titanium. So stainless steel would not be suitable material for the debridement brush of dental implant surface.
Understanding of modulus of elasticity:
The modulus of elasticity of diamond is 1,000-the top level of the sheet and the rubber is the one the lowest level of the sheet.
Smaller modulus of elasticity means “more flexible”
