A new shape memory alloy for endodontic practice: the single crystal CuAlBe
Abstract
Extract : The shape memory alloys(SMAs) are very interesting in endodontics because of their super-elastic properties. However, only the polycrystalline nickel-titanium (NiTi)is used in endodontics. The Cu-based single crystal SMAshows better responses in bending than the NiTi or Cu-based polycrystalline SMAs. This work investigateda new SMA with very promising propertiesfor endodontic canal preparation: the single crystal CuAlBe.
