This case report details the use of a digital workflow and ultrathin laminate veneers to restore esthetics and function to teeth with wear caused by bruxism and dental erosion. A 39-year-old man presented with wear on the occlusal surfaces of the posterior teeth, absence of anterior guidance, a noncarious cervical lesion (NCCL) in the maxillary right premolar, and esthetic concerns. A digital workflow was employed to create indirect laminate occlusal veneers (also known as tabletops), perform dental reanatomization with composite resin in the anterior region, and produce a veneer using a direct-indirect technique for the premolar with the NCCL. Evaluations revealed that there was no loss of vertical dimension or need for additional preparation. Ultrathin tabletops were manufactured from hybrid ceramic blocks using computer-aided design/computer-aided manufac¬turing technology and cemented with A2 shade flowable composite resin. A surface sealant was applied to protect the cement interface. For anterior reanatomization, a mock-up and palatal guide to composite resin layering were fabricated from the digital wax-up. The direct-indirect restoration for the NCCL was created outside the patient's mouth to ensure better precision and enable adjustment. The combination of a digital workflow and tabletop restorations for treatment of posterior tooth wear preserves natural tooth morphology in cases where no prior tooth preparation is required.
本病例报告详细介绍了使用数字化工作流程和超薄贴面修复因磨牙症和牙侵蚀导致磨损的牙齿的美学和功能。一名39岁男性患者出现后牙咬合面磨损、无前牙引导、上颌右前磨牙非龋性颈部病变（NCCL）以及美学问题。采用数字化工作流程制作间接贴面咬合面（也称为桌面），在前牙区域用复合树脂进行牙齿再解剖，并采用直接-间接技术为患有NCCL的前磨牙制作贴面。评估显示垂直距离无损失，也无需额外预备。超薄桌面由混合陶瓷块通过计算机辅助设计/计算机辅助制造技术制成，并用A2色可流动复合树脂粘结。应用表面密封剂保护粘结界面。对于前牙再解剖，根据数字化蜡型制作复合树脂分层的模型和腭侧导板。为NCCL制作的直接-间接修复体在患者口腔外制作，以确保更高的精度并便于调整。在无需预先进行牙齿预备的情况下，数字化工作流程与桌面修复相结合治疗后牙磨损可保留天然牙齿形态。
