@@@@BACKGROUND: Vital ium is the breakthrough in the materials of casting removable partial denture. OBJECTIVE: To summarize the alloying constituent, performance superiority and clinical application of Vital ium in medicine and other fields. METHODS: A computer search of Medline, CNKI and Wanfang databases was performed for relevant articles published from January 1970 to January 2012 using the keywords of “alloying constituent, performance superiority, interdisciplinary application” in English and Chinese, respectively. RESULTS AND CONCLUSION: Vital ium has been widely recognized in oral medicine and clinical medicine because of its particular alloying constituent and excel ent material performances. Compared with CoCr alloy, Vital ium has higher extension modulus and Vickers hardness. Therefore, the denture brackets made of Vital ium have higher rigidity and little transformation, meanwhile they are beautiful, comfortable, and easy to change but difficult to break off in the clinical practice, which expands the use and prolong the service life of the denture.
