Attempts to simplify impression disinfection lead to the production of an aseptic alginate impression material (Blueprint asept, De Trey/Dentsply, Konstanz, Germany). This study describes the aseptic properties of this new type of impression material. The in-vitro part of the experiments showed a reduction of Staphylococcus aureus by 6 and of Pseudomonas aeruginosa by 4 log steps after 60 min, and of Candida albicans by at least 3 log steps after 15 min of exposure. Under in-vivo conditions oral bacteria residing on the impression surfaces were reduced by nearly 4 log steps. Although the aseptic properties of the material were demonstrated, the biological acceptance, dimensional stability and compatibility with gypsum have to be tested in further studies.
为简化印模消毒，人们研发出了一种无菌藻酸盐印模材料（Blueprint asept，德国康斯坦茨德特雷/登士柏公司）。本研究描述了这种新型印模材料的无菌特性。实验的体外部分显示，暴露60分钟后，金黄色葡萄球菌数量减少6个对数级，铜绿假单胞菌数量减少4个对数级，白色念珠菌暴露15分钟后数量至少减少3个对数级。在体内条件下，印模表面的口腔细菌数量减少了近4个对数级。尽管该材料的无菌特性已得到证明，但生物可接受性、尺寸稳定性以及与石膏的兼容性仍需在进一步研究中进行测试。
