Several lubricant materials can be used to model resin-based composites (RBCs) during restorative procedures. Clinically, instruments or brushes are wet with bonding agents (BAs) or modeling liquids (MLs) for sculpturing purposes. However, a knowledge gap exists on their effects on the mechanical properties of RBCs, requiring greater insight. Five databases were searched, including 295 in vitro studies on the use of lubricant materials for modeling RBCs during restorative procedures. Only articles in the English language were included, with no limits on the publication date. The last piece of research was dated 24 March 2022. In total, 16 studies were included in the review process, together with a paper retrieved after screening references. A total of 17 BAs and 7 MLs were investigated. Tensile ( = 5), flexural strength ( = 2), water sorption ( = 2), color stability ( = 8) and translucency ( = 3), micro-hardness ( = 4), roughness ( = 3), degree of conversion ( = 3), and monomer elution ( = 2) tests were carried out. In general, a maximum of 24 h of artificial storage was performed ( = 13), while four papers tested the specimens immediately. The present review identifies the possibilities and limitations of modeling lubricants used during restorative procedures on the mechanical, surface, and optical properties of RBCs. Clinicians should be aware that sculpturing RBCs with modeling resins might influence the composite surface properties in a way that is material-dependent.
在修复过程中，可以使用几种润滑材料来模拟树脂基复合材料（RBCs）。临床上，器械或刷子会用粘结剂（BAs）或造型液体（MLs）浸湿以进行塑形。然而，关于它们对RBCs力学性能的影响存在知识空白，需要更深入的了解。检索了五个数据库，包括295项关于在修复过程中使用润滑材料模拟RBCs的体外研究。仅纳入英文文章，对出版日期无限制。最后一项研究的日期为2022年3月24日。总共有16项研究纳入了综述过程，还有一篇在筛选参考文献后检索到的论文。总共研究了17种BAs和7种MLs。进行了拉伸（=5）、弯曲强度（=2）、吸水率（=2）、颜色稳定性（=8）和半透明性（=3）、显微硬度（=4）、粗糙度（=3）、转化率（=3）以及单体洗脱（=2）测试。一般来说，最多进行24小时的人工储存（=13），而有四篇论文对标本进行了即时测试。本综述确定了修复过程中使用的造型润滑剂对RBCs的力学、表面和光学性能的可能性和局限性。临床医生应该意识到，用造型树脂塑造RBCs可能会以一种依赖材料的方式影响复合材料的表面性能。
