单尖法根管充填技术的研究进展

Advance of matched-taper single cone obturation technique

随着旋转镍钛器械在根管预备中的应用,单尖法根管充填也随之流行。单尖法相对于传统的冷牙胶侧压和热牙胶充填法,具有快速、与根管形态匹配良好、抗根折性能好等特点。本文就单尖法根管充填的原理、优缺点、研究进展作一综述,以期为临床提供参考。

With the widely use of rotary Ni-Ti files in the root canal preparation, taking matched-taper single cone techniques into use becomes popular. In contrast to the traditional cold lateral compaction and newly emerged warm gutta-percha techniques, single cone obturation is quick, highly efficient and well matching the root canal anatomy. This paper is to review the principles, improvements, advantages and drawbacks of single cone obturation tech- nique for clinical reference.
