摘　　要：目的:研究拔牙后创口愈合时间对种植体骨结合的影响,探讨拔牙后最佳种植体植入时间。方法:在拔除家犬的下颌双侧第二三前磨牙后不同时间植入种植体,3个月后处死动物观察种植体与拔牙窝之间新骨生成情况及密度并测量骨接触率。结果:0周组与3周组、6周组、9周组比较,差异有统计学意义(P<0.05),0周组的骨接触率明显低于3周组、6周组和9周组。3周组与9周组、6周组与9周组之间亦有非常显著性差异(P<0.05)。6周组的骨接触率略高于3周组,但统计学分析无显著性差异(P>0.05)。结论:在种植手术3个月时,即刻种植的骨接触率最低,拔牙3周、6周时种植的骨接触率无明显差异,拔牙后3周种植即能在短期内达理想骨结合。Objective：To investigate the effect of dental implants in different times on osseointegration after teeth extraction and evaluate the most proper implanting times.Methods：After extracting dog＇s teeth,we implant at different time interval（0,3,6,9weeks）,Three months later,the dogs were killed and the mandibles were separated.The bone-implant interface were histomorphometrically assessed using light microscope.Results：In Group 4,the new bone tissues were much more than that of the other three groups..There was no obvious difference between the Group2 and Group3.The differences among the other groups were significant.Conclusion：At 3 months after operation,the osseointegration of immediate implant is not perfect,the author think that implants implanted at 3 weeks after extraction is most for osseointegration suitable.
