摘要
目的应用共振频率分析法使用共振频率分析仪Osstell ISQ对比大颗粒喷砂酸蚀(SLA)和亲水性大颗粒喷砂酸蚀(SLActive)2种表面种植体的种植体稳定系数(ISQ)变化趋势,评价SLActive种植体临床预期性。方法 2011年1—9月就诊于广东省佛山市第二人民医院口腔修复中心的上下颌后牙区部分牙缺失患者55例,后牙区被植入33颗SLA种植体(SLA组)和34颗SLActive种植体(SLActive组),对比测量术后即刻、2周、4周、6周、12周种植体稳定性。结果 2组对比ISQ在术后2、4、6及12周的变化差异均有统计学意义(均P<0.05),而术后即刻差异无统计学意义(P>0.05)。结论 SLActive能促进骨结合,缩短愈合时间,增加临床预期性。
Objective The difference of implant stability quotient（ISQ）was compared between SLA and SLActive implants in the posterior mandible and maxilla by resonance frequency analysis（RFA）in order to evaluate the clinical predictability of Straumann SLActive implants.MethodsTotally 33 SLA and 34 SLActive implants were placed in the posterior mandible and maxilla of 55 patients. Each implant was tested by Osstell ISQ for RFA after being inserted for 0,2,4,6,and 12 weeks.Results Significant differences of ISQ were observed in the two groups（SLA and SLActive）after being implanted for 2,4,6,and 12 weeks. However,there was no significant difference after 0 week.Conclusion SLActive exhibits the advantages of improving osseo integration,shortening the healing time,and increasing the clinical predictability.
