摘要
目的:从细菌学角度探索种植体周围炎的发病机制,为进一步展开临床研究奠定基础。方法:在羊胫骨中部植入种植体,分别在术后4、6、9周收集经皮种植体周围炎性组织分泌物进行细菌学检测,通过涂片培养观察种植体周围炎性组织中菌群的变化,并观察种植体周围软组织的反应情况。结果:16枚种植体中5枚出现种植体周围炎,术后2个月炎症部位软组织红肿溃疡都极其明显,细菌学检测发现炎性分泌物中以G群链球菌感染为主并伴有其它菌的感染,G群链球菌的数量随炎症程度的增加而呈上升趋势。结论:经皮种植体周围炎的程度可能与G群链球菌的感染呈正相关。
Objective：To study the soft tissue inflammation of percutaneous implants using bacteria investigation method, so as to provide basic data for further clinical study of percutaneous implants. Methods： Implants were surgically placed into tibias of the goats. The inflammatory secretion from the peri-implant soft tissue was taken to perform bacteria test on 4, 6 and 9 weeks post-operation. Meanwhile, the soft tissue inflammatory reaction was also observed weekly. Results： 5 of the 16 implants were infected. The soft tissue showed tumefaction and ulceration 2 months post-surgery. As to bacteria investigation, the number of G. Streptococci increased when the inflammation was getting more severe. Conclusion： The extent of the soft tissue inflammation of percutaneous implants probably has positive correlation with the infection of G. Streptococci.
