超声骨刀在口腔种植中应用效果的初步探讨

【摘要】 目的 本研究通过观察、比较超声骨刀和传统球钻在Onlay植骨、上颌窦提升、骨劈开等手术中的临床应用效果，探讨超声骨刀在种植手术中的优越性及操作要点。方法 2006—2012年在常州市口腔医院种植科就诊，需要进行植骨手术的78例患者，总计80个术区，分别使用超声骨刀和传统球钻在Onlay植骨、上颌窦提升、骨劈开等手术中进行切骨操作；超声骨刀组42例，传统球钻组38例。分别于术后6 h、24 h、3 d进行复查，采用 VAS记录术后疼痛水平，利用SPSS11.5统计软件将临床数据采用等级资料秩和检验进行统计学分析。结果 超声骨刀组在术后6 h VAS均值为（3.98±2.16）、24 h VAS均值（2.35±1.86），传统球钻组在术后6 h VAS均值为（4.79±1.95）、24 h VAS均值（3.21±1.76），术后6小时、术后24小时两组间疼痛反应差异有统计学意义（p＜0.05）。结论 与传统球钻相比，采用超声骨刀进行种植植骨手术可以降低植骨术后短期疼痛发生率。

Application effect of piezosurgery in implant surgery:a preliminary study

Abstract Objective Through observation and comparison of piezosurgery and round bur applied in the implant surgery, including Onlay bone grafting, sinus lift, bone splitting, this research was aimed at seeking the advantages and the key points to use piezosurgery. Methods 80 operation areas of 78 patients from Department of Implantation,Changzhou Stomatological Hospital were operated with the piezosurgery and round bur during 2006-2012, piezosurgery 42 cases and round bur 38 cases. Usethe VAS to record the postoperative pain 6 hours, 24 hours and 3 days after operation. Using the SPSS11.5, all clinical data,including ranked data were analyzed by Mann-Whitney-Wilcoxon test. Results 6 hours after the operation, the mean score of VAS in the piezosurgery group（3.98±2.16）was lower than that of the round bur group（4.79±1.95）with statistically significant difference. 24 hours after the operation, the mean score of VAS in the piezosurgery group（2.35±1.86）was lower than that of the round bur group（3.21±1.76）with statistically significant difference. Conclusion Compared with round bur, using piezosurgery can decrease the occurrence rate of postoperative pain in short term.
