Trends in restorative composites research: what is in the future?

Abstract Clinical trials have identified secondary caries and bulk fracture as the main causes for composite restoration failure. As a measure to avoid frequent reinterventions for restoration replacement, composites with some sort of defense mechanism against biofilm formation and demineralization, as well as materials with lower susceptibility to crack propagation are necessary. Also, the restorative procedure with composites are very time-consuming and technically demanding, particularly concerning the application of the adhesive system. Therefore, together with bulk-fill composites, self-adhesive restorative composites could reduce operator error and chairside time. This literature review describes the current stage of development of remineralizing, antibacterial and self-healing composites. Also, an overview of the research on fiber-reinforced composites and self-adhesive composites, both introduced for clinical use in recent years, is presented.

临床试验已确认，继发性龋齿和体积性骨折是复合修复失败的主要原因。为了避免频繁进行修复替换的再干预，有必要采用具有一定生物膜形成和脱矿防御机制的复合材料，以及具有较低裂纹扩展倾向的材料。此外，复合材料的修复过程耗时且技术要求较高，尤其是在粘接系统的应用方面。因此，与大量填充复合材料相结合，自粘修复复合材料可以减少操作错误和椅旁时间。本文献综述描述了 remineralizing（再矿化）、antibacterial（抗菌）和 self-healing（自修复）复合材料的发展现状。同时，对近年来临床应用中引入的纤维增强复合材料和自粘复合材料的研发进行了概述。
