摘　　要：近年来新型树脂陶瓷复合材料已用于临床牙体修复和种植上部修复,主要包括高温聚合的树脂基质混合高比例分散的陶瓷填料(RBC)和聚合物渗透陶瓷网络(PICN)两大类,本文对树脂陶瓷复合材料的力学性能、美学效果及临床应用情况展开综述。结果显示,树脂陶瓷复合材料力学性能介于复合树脂与陶瓷之间,略高于复合树脂但显著低于增强型玻璃陶瓷和氧化锆陶瓷。此类材料的优势在于弹性模量与牙本质接近,同时相比陶瓷材料具有更佳的抗疲劳性。但在机械强度和断裂韧性方面仍有待进一步优化。树脂陶瓷复合材料的半透性不及增强型玻璃陶瓷,颜色稳定性介于复合树脂与陶瓷之间。临床疗效方面,目前主要用于嵌体、高嵌体和部分冠修复,并在短期的临床随访中表现出与陶瓷材料相似的存留率。PICN可能更适合用于种植体支持全冠修复。此类材料的长期临床效果仍有待更多的证据支持。In recent years,a new type of resin matrix ceramic composite material has already been applied to restore tooth defection as well as to manufacture crowns on implants.It mainly includes two categories:Resin-based ceramic(RBC)and polymer-infiltrated ceramic network(PICN).This paper provided a review of the mechanical properties,aesthetic characteristics,and clinical applications of resin matrix ceramic composite materials.The results indicated that the mechanical properties of resin matrix ceramic composite materials were between resin composite and ceramics,which were slightly higher than that of resin but significantly lower than that of reinforced glass-ceramics and zirconia.The advantages of such materials included their elastic modulus being close to that of enamel,and better fatigue resistance compared to ceramics.However,further optimization is needed in terms of mechanical strength and fracture toughness.The transparency of resin matrix ceramic composite materials was not as good as that of reinforced glass-ceramics,and their color stability was between resin composite and ceramics.In terms of clinical performance,resin matrix ceramic composite materials have been mainly used for inlays,onlays,and partial crowns currently,exhibiting similar survival rates to ceramics in the short-term clinical follow-ups.PICN may be more suitable for implant-supported full crowns.More evidence is needed to support the long-term clinical performance of these materials.
