Prefabricated glass fiber posts are widely used; however, their shape cannot be changed and they can be unsuitable for severely damaged teeth with wide root canals. This clinical report describes a procedure for restoring a severely damaged anterior tooth with a customized 1-piece glass fiber post and core, fabricated using a CAD/CAM system. This 1-piece glass fiber post and core adapts better to the root canal than a prefabricated glass fiber post, and reduces the cement layer thickness. Furthermore, it does not require the use of a composite resin foundation.
预制玻璃纤维桩被广泛应用,但它们的形状无法改变,对于根管较宽的严重受损牙齿可能不适用。本临床报告描述了一种使用 CAD/CAM 系统制作定制 1 件式玻璃纤维桩核来修复严重受损前牙的方法。与预制玻璃纤维桩相比,这种 1 件式玻璃纤维桩核更能适应根管,且可减少粘结层厚度。此外,它还不需要使用复合树脂基底层。
