目的研究临床两例重度弯曲根管的预备方法。方法使用小号不锈钢K锉探查通畅根管,并充分预备根管;换用Protaper旋转镍钛器械完成根管预备。结果重度弯曲根管预备完成,根管治疗完善。结论对于重度弯曲根管,仔细、恰当并充分使用小号不锈钢器械,结合旋转镍钛器械成形,可以达到良好的根管预备效果。
Objective To study the clinical preparation of two cases of severe curved root canal preparation. Methods The small stainless steel K-file was used to explore the open root canal, and the root canal was fully prepared. The root canal preparation was performed with the Protaper rotating nickel-titanium instrument. Results Severe curved root canal preparation is completed, and root canal treatment is complete. Conclusion For severe bending of the root canal, carefully, properly and fully using small stainless steel instruments, combined with rotary nickel-titanium equipment forming, can achieve good root canal preparation.
