A evolução das limas endodônticas atuais da PathFile à ProGlider e da WaveOne à era new golden

The Wave One Gold is a reciprocating file manufactured with a new alloy “the gold nickel titanium” characterized by excellent properties of resistance to both torsional and bending stresses. In comparison with the first generation of Wave One, the WaveOne Gold are more resistant to cyclic fatige (17,5%), much more resistant to torsional stress (53%), much more flexible (87%) and have less memory control, with less transport force in the canal. Due to their poligonal cross section, the WaveOne Gold can have one or two cutting edges, depending on location along the file Those alternating cutting points enable to minimize the screwing effect. Furthermore its semi-active tip facilitates its progression within the root canal and its lower taper minimizes the risk of apical extrusion of contaminated debris. The WaveOne Gold are available in 4 sizes: 20.06, 25.07, 35.06 and 40.05 thus giving to the clinicians more options to select the correct size and taper for the "single file" preparation. To optimize the use of wave one is is mandatory to negotiate first the root canal with a K-File #10, and create an expanded glide-path using a new file, the “Wave One Gold Glider” that is a single reciprocating file manufactured with the same gold alloy used for Wave1Gold
