2种方法治疗种植体植骨术后早期感染的临床比较

目的 探讨种植体植骨术后早期感染的临床治疗方案.方法 种植体植骨术后早期感染患者16例,共计28枚种植体.共采取2种治疗方法,方法1:彻底清创同期植骨,共处理患者9例,种植体16枚;方法2:取出种植体,重新种植,共处理患者7例,种植体12枚.通过评价种植体的存留率,比较2种处理方法的临床效果.结果 2例2枚种植体按照方法1处理后未取得预期效果,最终种植体失败取出,其余种植体均成功.2种方法处理的种植体10年累计存留率分别为87.5％ (14/16)、100.0％ (12/12),差异无统计学意义(x2=9.393,P=0.263).结论 彻底清创同期植骨和取出种植体重新种植均能有效解决种植体植骨术后的早期感染问题.

Comparison of two clinical approaches for early infection after bone augmentation of dental implant

Objective To investigate the treatment of early infected implants after bone augmentation.Methods A total of 28 failure implants from 16 cases were treated with thoroughly debriding and immediate bone grafting(16 implants,9 cases),or implants extracting and re-implanting(12 implants,7 cases),respectively.Then the clinical outcomes of the two methods were compared.Results Two implants failed in debridement group and others were all successful.The cumulated survival rates were 87.5% and 100.0% in the two groups,and there was no statistic difference(χ2=9.393,P=0.263).Conclusion Complications of dental implants after bone augmentation can be cured by either immediate or late re-implanting with debridement and bone grafting.
