摘要
目的:应用共振频率分析评估牙种植体初期稳定性和预测牙种植体骨结合,为上颌窦提升植骨同期植入种植体和种植体早期暴露的临床应用提供客观依据。方法:36个病人共植入87颗牙种植体,分为3组,A组种植体早期暴露组;B组上颌窦提升植骨同期种植组;C组常规种植组即对照组。在种植体植入即刻、二期暴露或修复负重前测定种植体稳定性,每一颗种植体前后测定2次。测定使用的仪器是共振频率分析仪Osstell,其数值单位是ISQ。结果:三组种植体初期稳定性数值范围是54.92-80.20ISQ。A组初期稳定性值最高,和其他两组之间的差异存在显著性。B组和C组之间差异没有统计学意义。骨结合形成后稳定性范围在57.94-79.38ISQ。三组种植体的后期稳定性之间差异没有统计学意义。A组和B组初期稳定性和骨结合形成后的稳定性数值前后没有差异,C组前后稳定性差异有统计学意义。结论:共振频率分析牙种植体初期稳定性和预测骨结合是一种可靠而有效的方法,同时也提示种植体早期暴露和上颌窦提升植骨同期种植术对具有适应症的病例是可行的。
To determine and evaluate the changes of implant stability in implant with sinus lift, the early exposure implants and standard placed implant in human using resonance trequency analysis（RFA）. Methods：： 87 implants in 36 patients were classified into 3 groups according to different clinical procedures, group A conrained implants experienced the early exposure （EE）, group B needed sinus lift with bone graft （SL） and the control group C （SE） had a traditional healing time advocated by Branemark. At the implant placement every implant was measured by RFA and the second measurement was done at second - stage or prosthodontical treatment. Results： The nomlal range of implant primary stability is 54.92- 80.20 ISQ. Group A had the highest stability, and the difference was significant, the other two groups had no significant difference between each other. The secondary stability range of RFA before prosthondics seems to be 57.94 - 79.38ISQ. There was no difference among the three groups. As for the sinus lift and early exposure, no statistical difference occurred, but there was some change of stability in the control group in their two measurements. Conclusion： Resonance Frequency Analysis of the implant primary stability and osseointegration is a reliable and effective assistant. The technique of sinus graft with simultaneous implant and early implant exposure in indicated cases should be predictable.
