中文摘要:
      CAD/CAM技术因方便快捷的特点,逐渐成为当今牙体修复的重要方式。近年来,聚合物浸渍陶瓷材料因具有良好切削性能受到了口腔从业者越来越多的青睐。这种新型材料内部呈现树脂与陶瓷互穿形态,兼具陶瓷和复合树脂性能特点,同时又具有自身独特的优势。与传统口腔修复材料(复合树脂和陶瓷)相比,聚合物浸渍陶瓷材料的弯曲强度为145MPa~336MPa,优于复合树脂和长石质可切削全瓷材料,低于二硅酸锂可切削全瓷材料。在模拟人类正常咬合时,聚合物浸渍陶瓷材料展现出极佳的耐疲劳性能,明显优于传统的二硅酸锂基、白榴石基和长石基可切削全瓷材料。此外,聚合物浸渍陶瓷材料弹性模量在25GPa~88GPa之间,维氏硬度在1.7GPa~4.8GPa之间,与天然牙体组织接近,预示着它有可能成为未来的牙科材料新星。改变内部组分含量可以调节聚合物浸渍陶瓷材料的机械性能,这个特点其他全瓷材料很少具有。目前,聚合物浸渍陶瓷材料的临床使用多集中在单冠修复,其长期使用效果(≥5年)的研究报道并不多见。新型牙科材料往往需要10年以上的时间才可能被更多牙科从业者了解和接受,因此,关于聚合物浸渍陶瓷材料的使用还处于探索阶段。本文在分析聚合物浸渍陶瓷材料组成结构的基础上,再结合其机械性能及目前使用情况,对聚合物浸渍陶瓷材料的未来使用提出建议,以期对聚合物浸渍陶瓷材料的研发和临床应用起到一定的指导作用。

英文摘要:
      CAD/CAM technology has become more and more popular in dental clinic. In recent years, polymer infiltrated ceramic network (PICN) material have attracted the attention of many dental practitioners owe to its good machinability. The new material shows the interpenetrating morphology of resin and ceramic, and its properties are similar to those of ceramic and composite resin, at the same time, it has its own unique advantage. Compared with the all- ceramic materials (composite resin and all- ceramic materials), the flexural strength of PICN materials ranged from 145 MPa to 336 MPa, which is better than that of composite resin and Feldspar- based machined ceramic materials, but is lower than that of lithium disilicate glass ceramics. In the study of simulating the normal occlusal condition of human beings, PICN materials show excellent fatigue resistance, which is obviously better than the traditional all- ceramic materials including Lithium, Leucite- based and Feldspar- based machined ceramic materials. In addition, Elastic modulus of PICN materials ranged from 25GPa to 88GPa and Vickers hardness value is between 1.7GPa and 4.8GPa, which is close to that of natural dental tissue, indicating that it maybe become a future star of dental materials. It can adjust the mechanical properties by changing the content of components, which is rare in dental all-ceramic materials. At present, PICN is mostly used as single crown restoration in dental clinic, but its long-term effect (≥ 5 years) is rarely seen. A new dental material often takes more than 10 years to be understood and accepted by more dental practitioners. Therefore, the application of PICN is still in the exploratory stage. Based on the analysis of the microstructure, properties and application of PICN, some suggestions are proposed for future research and dental application of PICN materials.
