摘要: 与传统不锈钢器械相比,机用镍钛器械因其优异的机械性能而在临床得到广泛应用。镍钛器械在根管治疗过程中发挥着清理成形根管、控制感染的关键作用,已成为根管预备的主流器械。然而,深知其具备高效切削力的同时,如何防止并发症的发生也成为我们关注的重点,因此镍钛器械的抗折性能一直是临床研究的热点。文章就影响镍钛器械抗折性能的因素及预防措施做一介绍。

Abstract: Compared with conventional stainless-steel instruments,engine-driven nickel-titanium instruments have been widely used in clinical practice because of their excellent mechanical properties. Nickel-titanium instruments play a key role in cleaning and shaping the root canal and controlling infection in the procedure of root canal therapy,and have become the mainstream instruments for root canal preparation. However,while having high efficient cutting efficiency,how to prevent the occurrence of complications has become the focus of our attention. Thus,the fracture resistance of nickel-titanium instruments has always been a key point of clinical discussion. In this article,influencing factors of fracture resistance and preventive measures were introduced.
Key words: nickel-titanium instruments, root canal therapy, fracture resistance, fatigue
