Abstract:

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.
