The aim of this article was to provide an overview of the literature on the currently available bulk-fill composites, and to describe the common trends as well as the wide variations. The findings may help the clinician to select the proper material with regard to its applicability in various clinical situations.
The literature up to October 2016 was reviewed based on a PubMed search (keywords: "bulk-fill OR bulkfill OR bulk fill" AND "composite OR composites").
This review revealed that bulk-fill composites differ most from conventional composites in their increased depth of cure, which could mainly be attributed to an increase in translucency. However, the literature is inconsistent regarding the determination of the depth of cure. Flowable "base" bulk-fill composites seem most suitable for narrow cavities deeper than 4 mm, in particular when a higher adaptation potential thanks to better flowability in less accessible cavity configurations is desirable. In more extensive cavities, "full-body" bulk-fill composites with a high filler load are preferable. Then, resistance against wear and fracture becomes increasingly important, while a thicker consistency might also help in obtaining a good contact point. Tests related to shrinkage stress induced by bulk-filling seem inconsistent and their clinical relevance is unclear.
More clinical studies that specifically focus on bulk-filling deep and large restorations are definitely required to fully explore the clinical benefits of bulk-fill composites.
本文旨在综述目前可用的大块充填复合材料的文献，并描述常见的趋势和广泛的差异。这些发现可能有助于临床医生根据其在各种临床情况下的适用性选择合适的材料。
根据 PubMed 检索（关键词：“bulk-fill OR bulkfill OR bulk fill”和“composite OR composites”），对截至 2016 年 10 月的文献进行了回顾。
本综述显示，大块充填复合材料在其固化深度方面与传统复合材料的差异最大，这主要归因于其透光率的提高。然而，文献中关于固化深度的测定并不一致。流动性“基底”大块充填复合材料似乎最适合于深度超过 4mm 的窄腔，特别是当在较难进入的腔结构中具有更好的流动性以获得更高的适应性潜力时。在更广泛的腔中，具有高填料负载的“全腔”大块充填复合材料是首选。然后，耐磨性和抗断裂性变得越来越重要，而更厚的稠度也有助于获得良好的接触点。与大块充填引起的收缩应力相关的测试似乎不一致，其临床相关性尚不清楚。
需要更多专门针对深部和大面积充填的临床研究，以充分探索大块充填复合材料的临床益处。
