摘要/Abstract

摘要： 目的利用共振频率分析（resonance frequency analysis,RFA）仪器监测经单纯上颌窦内提升（osteotome sinus floor elevation without grafting,OSFE without grafting）植入Strauamnn种植体的早期稳定性,分析上颌窦底剩余牙槽骨高度（residual bone height,RBH）对RFA结果的影响。方法采用单纯OSFE方式,对48例牙列缺损患者各植入1颗Straumann SLA宽颈美学种植体( 4.8 mm×8 mm)。用RFA仪器分别于手术当天、术后2、4、6、8、12、16、20周测量种植体稳定性,所得参数为种植体稳定系数（implant stability quotient, ISQ）。采用SPSS 17.0软件包对数据进行统计学分析。结果 48颗种植体的存活率为97.9%。所有种植体都获得了良好的初期稳定性。手术当天ISQ值较高,于第2周至第6周逐渐下降,之后逐渐上升,最终达到较高水平。上颌窦底剩余骨高度（residual bone height,RBH）与ISQ值无显著相关性。结论单纯OSFE方式在上后牙区严重骨量不足情况下仍可获得良好的种植体稳定性。RBH对于种植体的早期稳定性无显著影响。

Abstract: PURPOSE : To monitor the stability changes of Straumann implants placed by osteotome sinus floor elevation without grafting (OSFE without grafting) using resonance frequency analysis (RFA) during healing period, and analyses the effect of residual bone height on RFA. METHODS : Forty-eight Straumann implants ( 4.8 mm×8 mm) were placed in 48 patients with single tooth lost. Implant stability quotient (ISQ) was tested by RFA on the day of surgery and consecutively at 2, 4, 6, 8 ,12, 16 and 20 weeks after surgery. The data were analyzed using SPSS 17.0 software package. RESULTS : 97.9% survival rate was achieved in 48 implants and all implants had good primary stability at early stage. The mean ISQ value on the day of surgery was high and dropped to the lowest point at 4 weeks after surgery, then increased after 6 weeks in the stability curve. There was no significant correlation between residual bone height and ISQ value. CONCLUSIONS : Implant using OSFE placed at limited bone areas seems to have good implant stability. The RBH is not the main influential factor on implant stability.
