陶瓷材料及黏结技术在口腔美容过程中的应用

背景：牙科修复材料必须经过严格的生物学检验,使其不仅具有临床使用时所需的机械、物理、化学性能,而且必须具有良好的生物相容性。目的：评价陶瓷材料在牙科修复中的应用以及黏结技术对陶瓷修复体和宿主的影响。方法：采用电子检索的方式,在万方数据库(http://www.wanfangdata.com.cn/)中检索1999-01/2010-12有关陶瓷材料和黏结技术应用于牙齿修复的文章,关键词为“牙齿损伤,修补,材料,陶瓷,黏结剂,生物相容性”。排除重复研究、普通综述或Meta分析类文章,筛选纳入20篇文献进行评价。结果与结论：陶瓷独特的美学性能、极佳的生物相容性和优良的耐腐蚀性为全瓷修复奠定了基础,目前国内口腔修复用陶瓷的研究方向主要有熔附金属修复体、铝瓷以及微晶玻璃复合材料。不同系统陶瓷材料性质的不同,应使用配套的黏固剂,并根据产品说明进行酸蚀、喷沙等相应的的黏固前处理。全瓷修复体具有良好的光学性能,以较高的透明度、良好的力学性能和生物安全性等优点,在牙科美学修复中占有越来越重要的地位。

Ceramic materials and bonding technology in oral cosmetics

BACKGROUND:Dental restoration materials must undergo a rigorous biological testing, and the materials not only require mechanical, physical and chemical properties, but also have a good biocompatibility.OBJECTIVE:To evaluate the application of ceramic materials in dental restoration and to investigate the effect of bonding technology on ceramic restorations and the host.METHODS:An electronic search of Wanfang database was performed to retrieve articles about ceramic materials and bonding technology in dental repair published from January 1999 to December 2010. The keywords were “dental defect, repair, material, ceramic, adhesive, biocompatibility”. Repetitive studies, review and Meta analysis were excluded. Totally 20 papers were included in result analysis.RESULTS AND CONCLUSION:Ceramic has unique aesthetic properties, excellent biocompatibility and excellent corrosion resistance as the basis for all-ceramic restorations. Currently, the directions of dental ceramic research in China mainly include metal restorations, porcelain and glass-aluminum composite materials. Ceramic material properties of different systems are different, and matched cements should be used. In accordance with product instructions, etching, sandblasting and other appropriate pre-treatment should be done prior to use of dental cements. All-ceramic restorations with good optical performance, high transparency, good mechanical properties and bio-security play an increasingly important role in the dental repair.
