![]() The use of a single file for each patient is recommended as a new standard of treatment, presenting NiTi WaveOne® reciprocating files exclusively in pre-sterilised packages and with a handle that cannot be autoclaved. ![]() No time is wasted changing NiTi instruments during canal shaping and total shaping time is reduced by up to 40% compared to the traditional continuous rotation technique, while providing high quality treatments.The alternating twist technique allows most canals to be shaped using only one file.The optimised angles also reduce the risk of screwing and file breakage.A wide angle of rotation in the cutting direction provides high efficiency, while a smaller angle in the opposite direction allows the WaveOne® file to progress safely through the canal, respecting the anatomy of the canal.WaveOne® works with reciprocating rotational motion, the alternating rotation means that it continuously changes the direction of rotation during canal shaping.Higher risk of unnoticed fracture inside canals, contrary to stainless steel files that often present visible signs of plastic deformation.Įasyinsmile 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.Įasyinsmile Wire offers 3 levels of flexibility for choice, which depends on their crystallographic phases present in the alloy. Have superior properties in ductility, fatigue, recoverable strain, biocompatibility, and corrosion resistance. Use this Small W-ONE file to either initially or fully shape the apical one-thirdĮasyinsmile wire is a special heat-treated wire which be used for producing Endodontic rotary files.Īs we know, stainless steel instruments are rigid and therefore unsuited for large apical enlargement in thin curved canals. * In very rare cases you need to select the Small W-ONE file (YELLOW) if the Primary W-ONE file (25/08, RED) will not readily advance to the desired length. If the gauging file is loose at length, generally use a Large W-ONE file (DARK GREEN) to finish the preparation. If the gauging hand file is snug at length, the preparation is finished. 2) Gauge the size of the foramen with an ISO hand file that has the same diameter as the Primary V-TAPER? ONE file carried to working length. Irrigate, recapitu-late with a #10 K File and re-irrigate. * Methods for confirming the finished shape may include: 1) Checking if the apical flutes of the file are loaded with dentine. * Repeat Steps 4 and 5, two to three times until final working length has been achieved with the Primary W-ONE file. Irrigate, re-capitulate with a #10 K File and irrigate again. * It is important to withdraw the Primary W-ONE file every 3mms to remove the debris and inspect its cutting flutes. * Since most canals are between 9 and 15 mm in length, use a gentle inward motion, with short 1- 2 mm amplitude strokes, until it does not easily progress anymore. * In the presence of an irrigant, initiate shaping procedures starting with the Primary W-ONE file (RED). * Irrigate, then expand a glide path by C C- PATH FILE #12.5, or #15, or#20. * Explore the canal by using #10, or #15 stainless steel hand files In fact, the tougher the instrumenting challenge, like shaping severely curved to the apex, the more apparent the M-Wire NiTi’s advantages become. Strength- The M-Wire Nickel-Titanium technology provides overall flexibility and resistance to cyclic fatigue, the leading cause of file separation. Simplicity - W-one also simplifies the procedure, in most cases requiring just one NiTi instrument per root canal treatment.ģ. Control - The reciprocating technology means that it will only shape the canal when pressure is applied, giving you the feeling of complete control.Ģ.
