摘要
背景:冠修复体的严重磨耗会失去咬合功能甚至被磨穿,直接影响修复效果。目的:评价不同种类常用的牙齿修复材料与牙釉质之间的磨耗性能,寻求与天然牙釉质适应性较好的材料。方法:由第一作者检索1990-01/2010-02PubMed数据及万方数据库有关牙齿修补材料及不同修复材料与牙釉质磨损性能关系的相关文献,英文检索词为"dental materials;composite resins;dental enamel;abrasive wear",中文检索词为"牙釉质;修复材料;磨损;烤瓷;纳米复合体"。根据纳入标准,排除重复性研究,保留20篇文献进行分析。结果与结论:口腔是一个复杂的电解质环境,酸性饮食,茵斑堆积,细菌新陈代谢作用产生酸性物质,不论是无机酸还是有机酸,都会对金属的耐腐蚀性能产生不良影响。金属材料的化学稳定性好,耐腐蚀性强,与其表面形成的钝化膜有关,而非金属材料的耐腐蚀性则出现很大不同,参差不齐。磨耗性能牙科材料性能优良与否的主要因素,很多实验从牙科材料结构本身、牙齿磨损测量等多方面进行了深入研究,但对牙科材料的磨损机制研究还有待进一步深入。
BACKGROUND：Severe wear can lead to the loss of occlusal function or the crown restoration will be worn out,which directly affects the restoration results. OBJECTIVE：To evaluate the wear property between different types of dental restoration materials and dental enamel,and to seek a material adapting to natural enamel. METHODS：The first author retrieved PubMed database and Wanfang database from 1990 to 2010 for studies about dental repair materials and their wear relationships with dental enamel. English were ＂dental materials;composite resins;dental enamel;abrasive wear＂,and Chinese key words were ＂enamel;repair materials;wear;porcelain;nanocomposite＂. The repetitive research was excluded. Twenty papers meeting the inclusion criteria were included in further summary. RESULTS AND CONCLUSION：Oral cavity is a complex electrolyte environment,the acidic diet,plaque accumulation,and bacterial metabolism can produce acidic substances. No matter inorganic or organic acid,the corrosion resistance of the metal can adversely affect the results. Metal materials have good chemical stability and strong corrosion resistance,which are associated with the passive film formed on the surface,whereas the non-metallic materials exhibit different degrees of corrosion resistance. The wear properties are the major factor of dental materials and the existing experimental studies mainly focus on the structure of dental materials and wear measurements. However,further research is required to conclusively determine the wear mechanism underlying dental materials.
