摘　　要：弯曲根管的预备成形是根管治疗中的一大难点。近年来,随着新型镍钛器械不断发展,器械性能不断改进,对弯曲根管预备成形能力得以提升。本文就新型镍钛器械对弯曲根管预备成形能力的影响作一综述。Curved root canals are common in the clinic,and the complexity and variety of the curvatures make it difficult to maintain the original shape and perform ideal canal preparation.Recently,with the continuous development of new thermomechanical-treated nickel-titanium instruments,the performance of the instruments has been improved to better prepare the curved canals.In this paper,the effect of new thermomechanical-treated nickel-titanium instruments on the shaping ability of curved canals is reviewed.
