摘要： 目的对硅灰石(CaSiO3)涂层的生物学性能进行评价,为临床选择种植体表面改性方法提供实验依据。方法在纯钛棒表面采用等离子喷涂的方法分别加涂CaSiO3涂层和羟基磷灰石(HA)涂层,切割成直径3mm、高12mm的圆柱状植入体各12枚,植入实验狗的下颌骨内,检测种植体-骨界面的结合强度,并用扫描电镜进行形态观测。结果植入3个月后,CaSiO3涂层种植体-骨界面的剪切结合强度高于HA涂层种植体-骨界面的剪切结合强度,二者之间有显著差异(P<0.05)。结论CaSiO3涂层具有良好的生物活性,是一种较有应用前途的种植体涂层材料。

Abstract: Objective To evaluate the bioactivity and biocompatibility of the wollastonite coating(CaSiO3) and to provide the experimental basis for the clinical choice on the transformation methods of implant surfaces.Methods Six dogs were randomly divided into two groups.And 24 implants(12 sprayed with the hydroxyapatite coating,12 sprayed with the wollastonite coating) were randomly implanted into the mandibula of the dogs.The shearing bond stress of interface between implant and bone was measured with push-test.The...
