摘要 目的:评测口腔修复体用激光立体成形钛锆合金的细胞毒性。方法:采用激光立体成形的方法制备出钛锆合金的试件,根据国家标准制备试件的浸提液;通过体外细胞培养,四唑盐(MTT)比色方法评价材料的细胞毒性。结果:激光立体成形钛锆合金的细胞毒性为0~1级,阴性对照组、浸提液各浓度组细胞增殖曲线几乎重叠,并呈线性增加趋势。结论:激光立体成形的牙科钛锆合金材料具有较好的生物相容性。 Objective:To evaluate the cytotoxicity of dental Ti-Zr alloy made from laser solid forming. Method: Components of Ti-Zr alloy for test are made by loser solid forming and the deferent concentration water extracted from the components was obtained according to national standard. The extracts were measured by cell cultivation in vitro , MTT colorimetric to evaluate their cytotoxity. Result: The cytotoxicity of Ti-Zr alloy made from laser solid forming is 0 to 1 grade. The cell multiplication curve of negative control group and different concentration extracts are nearly overlapping and in the linearity increasing trend . Conclusion:Ti-Zr alloy made from laser solid forming has good biocompatity.
