结果：3个月后，实验组与对照组种植体周围骨小梁形成及纤维组织增生相近。

Result: After all animals were treated for 3 month , Trabeculation of bone around the implants of immediate implantion and delayed implantion was similar.

牵张结束时，血管密度由骨小梁形成区带（MCF）向纤维区带（FIZ）递减；

At the end of distraction, mierovessel density was decreased from microcolumn formation(MCF)zone to fibrous interzone(FIZ);

结果种植体植入后第14天，实验组和对照组种植体表面以及骨髓腔内均可见少量的新生小梁骨形成。
