复合树脂充填材料修复牙体缺损的应用价值及临床评价

Clinical value and evaluation of composite resin filling materials in dental defect repair

背景:各种复合树脂充填材料已成为牙体缺损修复治疗必不可少的重要材料,与合金修复材料并驾齐驱,但目前复合树脂的耐磨性能尚不够理想。目的:就近年来研究应用的各种复合树脂充填材料的特点进行总结及对比,为牙体缺损的生物材料和组织工程修补手段提供理论基础。方法:由第一作者于2010-12应用计算机检索PubMed数据库、万方数据库和维普数据库有关口腔复合树脂材料修复牙体缺损的文献。英文资料的检索时间为1999-01/2010-12,中文资料的检索时间为2000/2010-10;英文检索词为"composite resin,visible-light cured dental,detal adhesive materials,compatibility",中文检索词为"复合树脂,口腔充填材料,固化性能,生物相容性,口腔修复,纳米材料"。排除较陈旧文献及重复研究。阅读标题和摘要进行筛选,共纳入28篇进行分析。结果与结论:复合树脂是有机树脂基质经过表面处理的无机填料以及引发体系组合而成的牙体修复材料,作为牙色充填材料,具有可接受的物理机械性能,美观以及操作方便、易于修补等优点,在口腔修复领域使用越来越广泛。但复合树脂也存在聚合收缩、不耐磨、变色等缺点,尤其是其耐磨性能的不足,可导致修复物表面体积减小,以及修复体和边缘的破坏。随着纳米技术在生物医学领域的发展,复合树脂的纳米技术极大地丰富了口腔材料科学的研究领域,有望在牙齿修补领域带来更好的应用前景。

BACKGROUND： A variety of composite resin filling materials has become indispensable for dental defect repair, which is abreast of alloy materials. However, the wear resistance of composite resin is not ideal. OBJECTIVE： To summarize and compare different composite resin filling materials used in recent year for dental defect repair. METHODS： PubMed, Wanfang and VIP databases were searched for articles about the application of composite resin in dental defect repair with keywords of ＂composite resin, visible-light cured dental, dental adhesive materials, compatibility＂ in English （1999-01/2010-12） and ＂composite resin, oral filling materials, curing properties, biocompatibility, oral repair, nanomaterials＂ in Chinese （2000/2010-10）. Old and repetitive articles were excluded, and totally 28 articles were included in result analysis. RESULTS AND CONCLUSION： Composite resins are most commonly composed of organic resin matrix, inorganic filler, and photoinitiator. As a kind of dental filling materials, composite resins have acceptable mechanical properties and good appearance, and they are easy to operate and repair, which are used widely in dental repair. But there are also some shortcomings, such as shrinkage, poor wear resistance, and discoloration. The poor wear resistance can lead to a decrease in surface area and edge destroy of restorations. With the development of nanotechnology, composite resins are expected to have a better prospect in dental repair.
