摘　　要：目的　研究微直流电对即刻种植体周围骨组织的诱导作用及对骨整合的影响。方法　通过大体观察、组织学切片、扫描电镜等方法观察分析了微直流电对兔的下颌前磨牙拔除后的即刻种植体骨性界面组织的促进作用。结果　本实验所选用的微直流电可使实验组的种植体界面骨组织的形成比对照组早。结论　微直流电通过促进骨组织的矿化和代谢 。Objective To study low amperage direct current's effect on the osseointegration of nonsubmerged titanium dental implants. Methods We immediately implanted in the extraction sockets of the bicupids in the rabbits' mandibles, and the experimental implants were prepared to provide an electrical stimulation in the form of a constant direct current in 20μA with an hour per day. Then the effect was observed histologically and ultrastructurally. Result The LADC which we adopted promoted the amount of bone deposition, and earlier osseointegration interface was gained. Conclusion LADC may guide osteoblasts, then accelerate osseous rebuilding on the implant-bone interface.
