Nickel Titanium (NiTi) alloy was first applied to the root canal expansion formation field in the 1980s, about 40 years ago. NiTi files, which have contributed to the development of dental treatment, are still evolving and are being researched and improved by each company, and their viewpoint covers a wide range such as efficiency during cutting, torque, and rotational fatigue. While the required characteristics required with the times are changing, there is still nothing that can be called the final and completed form, and it will continue to evolve in the future. Needless to say, there is a lot of interest in NiTi files from users, as research and clinical reports on NiTi files are actively carried out every day.
Compared to stainless steel files, NiTi files, which have more flexible material characteristics, have higher root canal follow-up performance, less risk of inappropriate root canal formation such as ledges and zips, and more difficult cases can be handled. And improve the quality of medical care. On the other hand, due to the characteristics of the material, it is also true that signs of fracture are unlikely to appear and there is concern about sudden fracture. Our research results also revealed that this "abrupt rupture" is one of the major factors that makes it difficult for NiTi files to be adopted, while understanding excellent performance, and improvement of rupture durability is the most important issue. I thought However, in designing the file, in addition to this fracture durability, there are various factors such as cross-sectional shape, cutting efficiency, forming time, surface treatment method that must be considered, and sometimes each factor has a trade-off relationship. It is in. Taking these into consideration, the concept of "safety/safety" is the first step in the foundation of our file design, and when we are forced to decide which element to select, do not hesitate and follow the policy of leaning toward more safety and security. I continued. This is because all the wishes of "providing safety and security for the teachers and patients who are used" are included in this file.
