The use of computer-aided design/computer-aided manufacturing (CAD/CAM) dentistry has triggered novel approaches to restoring teeth in ways that increase efficiency, improve esthetics, and conserve tooth structure. Endodontically treated mandibular incisors offer a challenging restorative opportunity due to the small amount of natural tooth structure and the required amount of reduction needed for restorative material. The case presented demonstrates how to leverage chairside CAD/CAM technology to restore a discolored and fractured endodontically treated mandibular incisor without the use of a post and core and completing the restoration in a single visit.
计算机辅助设计/计算机辅助制造（CAD/CAM）牙科的使用开创了以提高效率、改善美观和保存牙体结构的方式修复牙齿的新方法。由于下颌切牙的天然牙体结构较少，需要为修复材料留出足够的空间，因此经过根管治疗的下颌切牙为修复提供了极具挑战性的机会。本病例展示了如何利用椅旁 CAD/CAM 技术来修复变色和折裂的下颌经根管治疗的切牙，而无需使用桩核，并在一次就诊中完成修复。
