Abstract: The in vitro biocompatibility (i.e. the cell proliferation and apoptosis of L929 cells) of 4 cast dental alloys (CoCrMo+1%Cu, CoCrMo+2%Cu, CoCrMo+3%Cu and CoCrMo) were evaluated by CCK-8 and Annexing-V/PI double marking methods to provide a biology reference in the clinical application of prosthodontics. Results show that the in vitro biocompatibility of 4 alloys decreases according to following sequence: CoCrMo+1%Cu, CoCrMo+2%Cu, CoCrMo and CoCrMo+3%Cu. However, the cytotoxicity grades of the 4 alloys are all ranked in level one, implying they are good enough in vitro biocompatibility.
