Currently, composite resins have become the material of choice for the restoration of posterior teeth. Although bulk-fill resins represent a tempting alternative due to their lower complexity and faster use, some dentists are reluctant to use this material. The objective is to compare the performance of bulk-fill resins and conventional resins in direct restorations of posterior teeth based on the literature. The databases that were used to carry out the research were PubMed/MEDLINE, Embase, the Cochrane Library and the WOS. This umbrella literature review complies with PRISMA standards and assesses the quality of studies using the AMSTAR 2 tool. With the application of the criteria of the AMSTAR 2 tool, the reviews were considered low to moderate. The overall meta-analysis, although without statistical significance, favours mostly the use of conventional resin, as it is about five times more likely to obtain a favourable result than bulk-fill resin. Bulk-fill resins result in a simplification of the clinical process of posterior direct restorations, which is an advantage. The performance in terms of several properties of bulk-fill resins and conventional resins showed that they present similar behaviour.
目前，复合树脂已成为后牙修复的首选材料。尽管大块充填树脂因其操作复杂性较低且使用速度较快而成为一种诱人的替代品，但一些牙医仍不愿使用这种材料。目的是根据文献比较大块充填树脂和传统树脂在后牙直接修复中的性能。用于开展该研究的数据库有PubMed/MEDLINE、Embase、Cochrane图书馆和WOS。这篇综合性文献综述符合PRISMA标准，并使用AMSTAR 2工具评估研究质量。根据AMSTAR 2工具的标准应用，这些综述被认为质量较低至中等。总体荟萃分析虽然没有统计学意义，但大多支持使用传统树脂，因为获得良好结果的可能性约是大块充填树脂的五倍。大块充填树脂简化了后牙直接修复的临床过程，这是一个优点。大块充填树脂和传统树脂在几种性能方面的表现表明它们具有相似的性能。
