Abstract

This study explores the potential application of computer aided design (CAD)/computer aided manufac-turing (CAM) for one-piece glass fiber posts and cores in restoring tooth defects post-removal of a broken fiber post using a digital guide plate. This paper reports a fractured left upper incisor fiber post removed using a customized needle and digital guide plate. Following root canal retreatment, CAD/CAM integrated fiber post-core and zirconia full crown restoration were completed. The occlusion testing was conducted using the T-Scan Ⅲ system. This study offers insights for managing secondary repair after fiber post fractures.
探讨采用数字化导板去除折断纤维桩后计算机辅助设计（CAD）/计算机辅助制造（CAM）一体化纤维桩核修复牙体缺损的应用前景。本文报道1例左上侧切牙纤维桩折断后采用定制车针及数字化导板引导下拆除，完成根管再治疗后CAD/CAM一体化纤维桩核及氧化锆全冠修复，并采用T-Scan Ⅲ系统进行咬合测试，为纤维桩折断后行二次修复提供参考。.
