MODERN ENDODONTICS IS BASED ON PRINCIPLES OF MINIMAL INTERVENTION.

One of the final objectives of the endodontic treatment is to preserve the biggest quantity of residual healthy dental structure because the latter plays a significant role on resistant to fracture of the treated tooth. Preservation of root dentine nowadays can be obtained by using very performing instruments, which will be very flexible and will respect the anatomy of the root canals. Recently, the instruments producing companies have concentrated their efforts not only on the modification of the design of the NiTi instruments, but also on the improvement of the characteristics of the NiTi alloy. The NiTi alloy has got three different microstructural phases, depending on the temperature: austenitic, martensitic and R-phase. The austenitic NiTi is hard and resistant, while the martensitic and R-phase NiTi are soft and ductile and can be easily deformed.

Consequently, the mechanical characteristic of the NiTi are influenced by the composition of the three phases. The conventional NiTi alloy is mostly in the austenitic phase at room temperature, but thermo mechanic treatments can keep the alloy in the martensitic phase, in R-phase or in a mixed form, altering the transformation temperature, and therefore changing the characteristics of the alloy.

• +70% Flexibility
• Pre-curved : It can be pre-curved and has an extreme efficiency in the most curved canals.
• +40% Resistance
• High Resistance : CM wire alloy with special heat treatment give a very high resistance and flexural fatigue.
