Zarc4endo – Comportamiento de las limas de NiTi en el sistema de conductos: Blue Shaper, la sexta generación de instrumentos

The use of rotary NiTi systems is today the best option to make a predictable, fast and effective root canal preparation. In this workshop we will focus on the behavior of NiTi instruments inside the canal. We will try to explain scientifically and with numerous studies how some changes in the design, alloy and mechanical movement can improve the behavior of our NiTi rotary instruments. We will try to identify the stresses (torsional and flexional) that our instruments face to try to prevent future fractures. We will also assess the deformations suffered by the instruments after modeling the canals, associating them with the areas of greatest torsional and flexural stress. We will introduce the new BlueShaper mechanical instrumentation system (ZARC4ENDO – Spain), comparing it with the rest, analyzing its advantages, design and behavior.
