From Kleber K. T. Carvalho – many thanks for his largesse
One of the great advantages of the XP-endo Finisher is to achieve working length while maintaining its expansion feature while inside the root canal, even in extreme curvatures.
This video illustrates this feature.
The metal tube with extreme curvature has a diameter slightly greater than 30. The XP-endo Finisher, because its diameter 25, easily enters the tube, its flexibility allows to follow without difficulty the extreme curvature.
Inside the tube the XP-endo Finisher is trying to expand, but is limited by the “canal” walls.
When it goes beyond the length of the tube, finding free space, its property of expansion is evident.
Enjoy the video!
