不同口腔修复材料生物相容性及3种材料充填恒磨牙邻面龋的临床验证

Clinical verification of biocompatibility of different dental materials and three filling materials on the interproximal caries of permanent molars

背景:高强度、良好的适合性、可以接受的美学效果等都是牙科固定修复体所必须的。在材料的具体选择上应根据牙齿缺损的部位、范围以及有无龋坏组织等具体情况去选择。那么,哪一种材料更具有良好的性能及生物相容性呢?目的:从材料学及临床应用方面总结不同口腔修复材料的生物相容性,并评价了玻璃离子水门汀、银汞合金、光固化复合树脂充填恒磨牙邻面龋的临床疗效。方法:以"口腔修复;材料;陶瓷;合金;相容性"为中文关键词;以"interproximal caries;permanent molar;filling"为英文关键词,采用计算机检索2000-01/2010-10相关文章。纳入与不同材料在口腔修复中的应用及相容性分析相关的文章;排除重复研究或Meta分析类文章。以25篇文献为主重点分析对象讨论了口腔不同修复材料性能的重要性。结果与结论:传统的合金类修复材料普遍存在硬度高、耐磨损等缺点,但因依靠机械固位,且修复洞缘微漏现象明显,必须严格制备洞型;而陶瓷类或粉剂类有黏着性,但硬度低,边缘密台性差。而随着纳米材料与技术的兴起和迅速发展,将口腔材料与纳米材料技术相结合,在引进改性和创新中,形成一种全新的理念、新的材料技术模式,必将在口腔医学领域中取得突破性进展。

BACKGROUND：High strength,good aptness,and acceptable aesthetic effect are all necessary for fixed partial denture（FPD）.The specific choice of materials should be based on the site of tooth defects,scope and have or not carious organizations.Therefore,which kind of materials has good performance and biocompatibility？ OBJECTIVE：To summarize the biocompatibility of different dental materials from the aspect of hylology and clinical application,and to evaluate the clinical effect of radiopaque glass Ionomer luting cement,silver amalgam,light-cured composite filling materials on the interproximal caries of permanent molars.METHODS：The articles from January 2000 to October 2010 was retrieved,with the key words of ＂dental rehabilitation,materials,ceramics,alloy,compatibility＂ in Chinese,and ＂interproximal caries,permanent molar,filling＂ in English.The articles related to the application and compatibility of different materials on mouth rehabilitation were included,duplicate and Meta-analysis documents were excluded.It is better to cite mainly the 25 literatures and to discuss the importance of the properties of different dental materials.RESULTS AND CONCLUSION：The traditional alloy restorative material commonly has the disadvantages of high hardness,wear resistance,but which relies on mechanical retention,and has obvious repair hole edge micro-leakage,must be strictly prepare cavity.However,ceramic and pulvis has adhesion,low hardness,and poor marginal microleakage.With the emergence and rapid development of nano-materials and technology,dental materials combined with nano-materials technology,a new idea and material technology model were formed in the introduction of modification and innovation,it will achieved breakthrough in the field of stomatology.
