Abstract

Zirconia and resin are the most commonly utilized materials in dental restorations. However, zirconia presents significant wear on opposing teeth, whereas resin materials have low wear resistance and mechanical performances. A zirconia-resin interpenetrating phase composite (IPC) dental restoration was designed and fabricated using 3D printing and vacuum infiltration processes, incorporating zirconia scaffolds with triply periodic minimal surfaces (TPMS) structures. The mechanical and tribological performances of the IPCs were investigated through compressive and tribological experiments and finite element analysis, elucidating the influence of zirconia volumetric fraction. Results showed that IPCs exhibit excellent mechanical and tribological compatibilities, which can reduce the damage and wear of the antagonistic teeth. This designing and manufacturing strategy enables the IPC restorations with promising applications in dentistry.

具有 TPMS 结构的仿生互穿相氧化锆-树脂复合牙科修复体的设计与增材制造。

氧化锆和树脂是最常用的牙科修复材料。然而，氧化锆对对齿磨损严重，而树脂材料的耐磨性和机械性能较低。利用三维打印和真空渗透工艺设计并制造了一种氧化锆-树脂互穿相复合材料（IPC）牙科修复体，其中包含具有三周期最小表面（TPMS）结构的氧化锆支架。通过压缩和摩擦学实验以及有限元分析，研究了 IPC 的机械和摩擦学性能，阐明了氧化锆体积分数的影响。结果表明，IPCs 表现出优异的机械和摩擦相容性，可减少拮抗齿的损坏和磨损。这种设计和制造策略使 IPC 修复体在牙科领域的应用前景广阔。

期刊介绍： The Journal of the Mechanical Behavior of Biomedical Materials is concerned with the mechanical deformation, damage and failure under applied forces, of biological material (at the tissue, cellular and molecular levels) and of biomaterials, i.e. those materials which are designed to mimic or replace biological materials. The primary focus of the journal is the synthesis of materials science, biology, and medical and dental science. Reports of fundamental scientific investigations are welcome, as are articles concerned with the practical application of materials in medical devices. Both experimental and theoretical work is of interest; theoretical papers will normally include comparison of predictions with experimental data, though we recognize that this may not always be appropriate. The journal also publishes technical notes concerned with emerging experimental or theoretical techniques, letters to the editor and, by invitation, review articles and papers describing existing techniques for the benefit of an interdisciplinary readership.
