As the most advanced aerogel material, silica aerogel has had transformative industrial impacts. However, the use of silica aerogel is currently limited to the field of thermal insulation materials, so it is urgent to expand its application into other fields. In this work, silica aerogel/resin composites were successfully prepared by combining silica aerogel with a resin matrix for dental restoration. The applications of this material in the field of dental restoration, as well as its performance, are discussed in depth. It was demonstrated that, when the ratio of the resin matrix Bis-GMA to TEGDMA was 1:1, and the content of silica aerogel with 50 μm particle size was 12.5%, the composite achieved excellent mechanical properties. The flexural strength of the silica aerogel/resin composite reached 62.9546 MPa, which was more than five times that of the pure resin. Due to the presence of the silica aerogel, the composite also demonstrated outstanding antibacterial capabilities, meeting the demand for antimicrobial properties in dental materials. This work successfully investigated the prospect of using commercially available silica aerogels in dental restorative materials; we provide an easy method for using silica aerogels as dental restorative materials, as well as a reference for their application in the field of biomedical materials.
作为最先进的气凝胶材料，硅气凝胶在工业领域产生了变革性的影响。然而，硅气凝胶的应用目前仅限于隔热材料领域，因此迫切需要将其应用扩展到其他领域。在这项工作中，通过将硅气凝胶与树脂基体结合，成功制备了硅气凝胶/树脂复合材料，用于牙科修复。深入探讨了该材料在牙科修复领域的应用及其性能。结果表明，当树脂基体 Bis-GMA 与 TEGDMA 的比例为 1:1，粒径为 50μm 的硅气凝胶含量为 12.5%时，复合材料具有优异的力学性能。硅气凝胶/树脂复合材料的弯曲强度达到 62.9546 MPa，是纯树脂的五倍多。由于硅气凝胶的存在，复合材料还表现出出色的抗菌能力，满足了牙科材料对抗菌性能的需求。这项工作成功地研究了将市售硅气凝胶应用于牙科修复材料的前景；为将硅气凝胶用作牙科修复材料提供了一种简单的方法，并为其在生物医学材料领域的应用提供了参考。
