摘　　要：目的 应用共振频率分析方法评估侧壁开窗上颌窦底提升术植入种植体一期愈合后采用渐进性负重方案修复对种植体稳定度的影响。方法 选取22例需进行侧壁开窗上颌窦底提升骨增量术进行种植治疗患者,共植入22颗种植体,在术后即刻、二期手术及最终修复时分别使用共振频率分析仪测定种植体稳定度系数(ISQ),并记录种植体留存率。结果 修复时种植体留存率100%,未出现明显手术并发症;种植体稳定度在经过一期愈合及渐进性负重后均有了显著提升(P<0.05)。结论 渐进性负重方案的采用,促进了种植体周围骨组织的改建,增加了种植体的稳定度。Objective To evaluate the stability of the implant that placed simultaneous with the maxillary si⁃nus floor augmentation through the progressive loading pattern using the resonance frequency analysis(RFA).Methods A total of 22 implants placed simultaneous with the maxillary sinus floor augmentation were inserted in 22 patients.The implant ISQ was measured suing the RFA respectively at the immediately after implant insertion,the secondary stage sur⁃gery and the final restoration time.Also the implant survival rate was recorded.Result The residual rate of the implants in the two groups was 100%,and no obvious complications occurred.The stability of the implants in the experimental group was significantly higher than that in the control group after progressive weight bearing(P<0.05).Conclusion The adoption of the progressive weight⁃bearing scheme promotes the reconstruction of the bone tissue around the implant and increases the stability of the implant compared with the conventional weight⁃bearing scheme.
