本研究的目的是评价计算机辅助设计/计算机辅助制造(CAD/CAM)纤维增强复合材料(FRC)义齿固位体的抗折性能。采用计算机辅助设计/计算机辅助设计(CAD/CAM)或传统的聚合方法制作带有两个套筒固位体和两个磨牙桥的远中延伸义齿，分别使用或不使用玻璃纤维。义齿在第二磨牙桥上承受垂直载荷，直至折断。在每种制造方法中，FRC的埋入都增加了平均最终断裂载荷，这表明玻璃纤维的增强作用。使用FRC的聚合义齿的平均最终断裂载荷大于使用FRC的CAD/CAM义齿。
The purpose of this study was to evaluate the fracture resistance of computer-aided design/computer-assisted manufacture (CAD/CAM)-fabricated fiber-reinforced composite (FRC) denture retainers. Distal extension dentures incorporating two telescopic retainers and two molar pontics, with or without fiberglass, were fabricated by CAD/CAM or by the conventional polymerization method. The dentures were subjected to a vertical load on the second molar pontic until fracture. Within each manufacturing method, embedment of the FRC increased the mean final fracture load, suggesting the reinforcing effect of fiberglass. The polymerized dentures with FRC showed greater mean final fracture load than the CAD/CAM dentures with FRC.
