摘要：

目的：总结光固化复合树脂在牙体大面积缺损修复中的临床效果。
方法：应用计算机检索维普数据库(网址http://www.cqvip.com/)、中国期刊全文数据库(http://www.cnki.net/)。以“牙体大面积缺损，树脂，光固化复合树脂，修复”为关键词，检索牙体大面积缺损后修复，光固化复合树脂修复牙体大面积缺损等临床研究及进展相关文献。
结果：光固化复合树脂是超微填料型的复合树脂，其流动性黏稠度适中，不粘器械，操作简便，操作时间充裕，易准确塑形，色域广，临床选择范围大，抛光后色泽亮丽自然，机械性能好，耐磨性高，对患牙而言可少磨牙或不磨牙，脱落后可重新修复，对患者而言治疗时间短且可一次完成，因此光固化复合树脂目前广泛应用于牙体大面积缺损的修复。但常用的树脂仍存在一些问题和缺陷，主要表现为弹性模量和耐磨性差与银汞合金相比，采用更高硬度的填料或增强填料与树脂基体的结合力，可以改善这方面的性质。
结论：Durfill光固化复合树脂在临床修复牙体大面积缺损中，操作简单易行，提高患者的美观性需求，是修复牙体大面积缺损的一种较好的修复方法，值得临床广范应用。

Abstract:

OBJECTIVE: To summarize clinical effect of light-cured composite resin in the restoration of large-scale tooth defects.
METHODS: A computer search was performed in VIP database (http://www.cqvip.com/) and China Academic Journal Full-text Database (http://www.cnki.net/) using “large-scale tooth defects, resin, light cured composite resin, restoration” in Chinese as the key words, for articles related with the clinical study and advanced progress regarding light-cured composite resin restoration of large-area tooth defects.
RESULTS: The light-cured composite resin is type of ultramicro composite resin filler, with moderate fluid viscosity, it cannot stick to the device and easily operated, operation time is ample, the shaping is accurate, color gamut is wide, clinical selection range is great, the polished luster is beautiful nature, mechanical properties are good, wear resistance is high, the affected teeth avoid grinding, the exfoliated can be restored, the treatment can be completed in a short time, therefore light-cured composite resins have been widely used in the current restoration of large-area tooth defects. Common resins still have some shortcomings, mainly poor elastic modulus and wear resistance compared with silver amalgam alloy, hardening filler or enhancing the binding strength of filler and resin matrix can improve the characteristics.
CONCLUSION: Durfill light-cured composite resin is a simple, convenient method for the restoration of large-area tooth defects, it raises the aesthetics needs of the patients, thus worthy of wide application in clinical practice.
