Easyinsmile wire is a special heat-treated wire which be used for producing Endodontic rotary files.

Endodontic File rotary AF-R wire file Easyinsmile for 10-15 posterior canals is a new invention using memory alloy material in order to prevent the dentists away from breaking file accidentally or technically inside the root canal.

As we know, stainless steel instruments are rigid and therefore unsuited for large apical enlargement in thin curved canals. NiTi alloys have superior properties in ductility, fatigue, recoverable strain, biocompatibility, and corrosion resistance. However, NiTi files present a higher risk of unnoticed fracture inside canals, contrary to stainless steel files that often present visible signs of plastic deformation.

Easyinsmile Wire is a developed NiTi alloy, which ideally have excellent mechanical strength properties, and its flexibility is enough to avoid canal transportation, meanwhile its hardness is large enough to allow for good cutting efficacy.

Easyinsmile Wire offers 3 levels of flexibility for choice, which depends on their crystallographic phases present in the alloy.
