中文摘要
根管治疗是牙髓及根尖周疾病的主要治疗手段，为了增进根管清理和成形的效果，不同材质和设计的根管预备器械不断涌现，其中机用镍钛预备器械极大提高了根管预备效率。然而，随着根管系统解剖复杂性、根管治疗目的和预后的认识的深入，临床实践对机用镍钛预备器械提出了新需求，这些基于临床导向的需求为器械改革创新提供了动力。目前镍钛预备系统不断推陈出新，新型机用镍钛预备系统的改良及优势何在，其如何提高根管预备效率，本文拟对这类问题进行系统阐述。
英文摘要
Root canal therapy is the primary treatment method for pulpal and periapical diseases. Various advanced endodontic instruments for mechanical preparation have been marketed. The emergence of nickel-titanium rotary instruments has greatly improved the efficiency of root canal preparation. New demands have been put forward for nickel-titanium rotary instruments as a result of the deepening of clinicians’ awareness of root canal anatomy system as well as the purpose and prognosis of root canal treatment. These clinical-oriented demands accelerate instrument reform and innovation. This work presents new marketed nickel-titanium systems and discusses the advantages and limitations of these systems and how they perform in terms of the efficiency and outcome of root canal preparation.
