摘要: 目的:研究种植体稳定系数(implant stability quotient, ISQ)评估种植体骨结合状况的有效性和可靠性,评价超声共振频率分析(resonance frequency analysis,RFA)技术作为种植体负载时机评价指标的可行性。方法:经腭入路行犬上颌窦提升术同期植入种植体,模拟骨量不足状态下的上颌后牙区种植动物模型,并于术后即刻、4、 8、12周对种植体稳定性进行测量。采用影像学检查、组织形态学分析和临床指标分析,进一步验证ISQ值与种植体骨结合状态的相关性,从而对RFA技术临床应用的有效性和可靠性进行评价。采用SAS 9.4 软件包进行Pearson相关性分析。结果:全部种植体骨结合成功。种植体植入即刻ISQ值达65左右,术后4、 8、12周,逐渐升高至67以上。在整个测量过程中,未发现任何种植体松动现象。各种植体稳定性在整个实验过程中的变化趋势基本一致,骨结合率无明显差异。ISQ值与剩余骨高度(residual bone height,RBH)间无显著相关性。结论:ISQ值与RBH之间无明显相关性,ISQ值不是评估种植体骨结合状态的有效手段,RFA技术作为种植体负载时机选择的依据缺乏足够的证据支持。

Abstract: PURPOSE: The aim of this study was to evaluate the validity and reliability of implant stability quotient(ISQ)used for assessing of the condition of bone-to-implant interface and to evaluate the influence of residual bone height on ISQ values in canine models. METHODS: Six Labrador dogs with bilateral sinus lift procedure and simultaneous implant placement were served as animal models. ISQ measurement was applied at 0, 4, 8, 12 weeks postoperatively. Radiographic assessment,histomorphology and clinical analysis were used to evaluate the correlation between ISQ value and bone-to-implant contact,and the validity and reliability of RFA technique in atrophic posterior maxillae. Statistical analysis was carried out using SAS 9.4 for Pearson's correlation analysis. RESULTS: All implants were successfully osseointergrated. The mean ISQ value measured immediately after implant placement was 65. At 4, 8, 12 weeks after operation,the mean ISQ value reached a higher level of 67. During the whole study period, there was no implant failure. The change of implants stability pattern was similar among different groups, no significant difference in bone-to-implant contact was observed. There was no significant correlation between ISQ value and residual bone height(RBH) value. CONCLUSIONS: Within the limitation of the study, it may be implied that ISQ values are not suitable for assessing the condition of bone-to-implant interface and the role of single RFA measurement in determining loading protocol is questionable.
