This work aims to review the key factors affecting the polymerization efficiency of light-activated resin-based composites. The different properties and methods used to evaluate polymerization efficiency will also be critically appraised with focus on the developments in dental photopolymer technology and how recent advances have attempted to improve the shortcomings of contemporary resin composites.
Apart from the classical literature on the subject, the review focused in particular on papers published since 2009. The literature research was performed in Scopus with the terms "dental resin OR dimethacrylate". The list was screened and all papers relevant to the objectives of this work were included.
Though new monomer technologies have been developed and some of them already introduced to the dental market, dimethacrylate-based composites still currently represent the vast majority of commercially available materials for direct restoration. The photopolymerization of resin-based composites has been the subject of numerous publications, which have highlighted the major impact of the setting process on material properties and quality of the final restoration. Many factors affect the polymerization efficiency, be they intrinsic; photoinitiator type and concentration, viscosity (co-monomer composition and ratio, filler content) and optical properties, or extrinsic; light type and spectrum, irradiation parameters (radiant energy, time and irradiance), curing modes, temperature and light guide tip positioning.
: This review further highlights the apparent need for a more informative approach by manufacturers to relay appropriate information in order for dentists to optimize material properties of resin composites used in daily practice.
本工作旨在综述影响光固化树脂基复合材料聚合效率的关键因素。本文还将对不同的性能和评估聚合效率的方法进行批判性评价,重点关注牙科光聚合技术的发展以及最近的进展如何试图改善当代树脂复合材料的缺点。
除了该主题的经典文献外,本综述特别关注了自 2009 年以来发表的论文。文献研究在 Scopus 中进行,使用了“牙科树脂 OR 二甲基丙烯酸酯”这一术语。对清单进行了筛选,并纳入了所有与本工作目标相关的论文。
尽管已经开发出了新的单体技术,其中一些已经被引入牙科市场,但基于二甲基丙烯酸酯的复合材料目前仍然代表了直接修复中可获得的绝大多数商业材料。树脂基复合材料的光聚合已经成为许多出版物的主题,这些出版物强调了聚合过程对材料性能和最终修复质量的重大影响。许多因素会影响聚合效率,包括内在因素(如光引发剂类型和浓度、粘度(共聚单体组成和比例、填料含量)和光学性能)和外在因素(如光的类型和光谱、辐射参数(辐射能量、时间和辐射照度)、固化模式、温度和光导尖端定位)。
本综述进一步强调了制造商需要以更具信息量的方式进行宣传,以便牙医能够在日常实践中优化所使用的树脂复合材料的性能。
