摘要:

背景: Vitallium的引进是铸造可摘义齿支架材料方面的一个突破性进展。
目的:综述Vitallium的合金成分、材料性能优势、在临床医学及其他领域的应用。
方法:应用计算机检索Medline数据库(1970年1月至2012年1月),以“alloying constituent,performance superiority,interdisciplinary application”为检索词;应用计算机检索中国知网数据库(1970年1月至2012年1月)、万方数据库(1970年1月至2012年1月),以“合金成分,性能优势,跨领域应用”为检索词。
结果与结论:Vitallium由于其独有的合金成分、明显的材料性能优势获得了在口腔医学及临床医学如骨科以及肝胆外科等其他领域的广泛认可。与常用钴铬合金相比较,Vitallium具有较高的延展系数和维氏硬度,在临床应用中用其铸造的义齿支架刚性较大,变形小,不易折断,美观且舒适易调改,拓展了修复体的用途,延长了修复体的使用寿命。

Abstract:

BACKGROUND: Vitallium is the breakthrough in the materials of casting removable partial denture.
OBJECTIVE: To summarize the alloying constituent, performance superiority and clinical application of Vitallium 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: Vitallium has been widely recognized in oral medicine and clinical medicine because of its particular alloying constituent and excellent material performances. Compared with CoCr alloy, Vitallium has higher extension modulus and Vickers hardness. Therefore, the denture bracketsmade of Vitallium 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.
