Abstract：
Prefabricated glass fiber-reinforced composite posts have been widely used because of their esthetic properties and favorable biomechanical behavior; however, because they are prefabricated, they may not adapt to the anatomy of all root canals. This case report describes a procedure for restoring teeth with a custom, 1-piece, fiber-reinforced composite post and core fabricated using computer-aided design/computer-aided manufacturing (CAD/CAM). The excellent adaptation of this custom endodontic post enables the use of a thinner, homogenous cement layer; in addition, it eliminates the need to construct a composite resin core build-up. Although more clinical and in vitro studies are needed to better define the appropriate clinical protocols and assess various materials, CAD/CAM technology allows post and core restorations to be manufactured in a predictable and simplified way.
摘要：
预制玻璃纤维增强复合材料桩因其美学性能和良好的生物力学行为而得到广泛应用；然而，因为它们是预制的，它们可能不适应所有根管的解剖结构。此病例报告描述了一种习惯修复牙齿的程序，1件,使用计算机辅助设计/计算机辅助制造（CAD/CAM）制造的纤维增强复合材料柱和芯。这个定制的牙髓柱的优秀适应使稀释剂的使用，均质水泥层；此外，它消除了构建复合树脂芯的需要。尽管需要更多的临床和体外研究来更好地定义适当的临床方案并评估各种材料，CAD/CAM技术允许以可预测和简化的方式制造桩和芯修复体。
