Abstract：
Noncarious lesions, a multifactorial condition encompassing tooth attrition, abrasion, and erosion, have a surge in prevalence and required increased attention in clinical practice. These nonbacterial-associated tooth defects can compromise aesthetics, phonetics, and masticatory functions. When providing full-arch fixed occlusal rehabilitation for such cases, the treatment strategy should extend beyond by restoring dentition morphology and aesthetics. This report details a complex case of erosive dental wear addressed through a fully digital, full-arch fixed occlusal rehabilitation. A 4D virtual patient was created using multiple digital data sources, including intraoral scanning, 3D facial scanning, digital facebow registration, and mandibular movement tracing. With a comprehensive understanding of the masticatory system, various types of microinvasive prostheses were customized for each tooth, including labial veneers, buccal-occlusal veneers, occlusal veneers, overlays, inlays, and full crowns, were customized for each tooth. The reported digital workflow offered a predictable diagnostic and treatment strategy, which was facilitated by virtual visualization and comprehensive quality control throughout the process.
牙磨耗、磨损、酸蚀症等多因素导致的非龋性牙体缺损在口腔临床中的发病率呈上升趋势，通常伴随着不同程度的口腔美学缺陷及功能障碍。对其进行全牙列固定修复咬合重建时，不仅要恢复牙列的形态和美观，更要实现咬合关系与整体口颌系统的协调。本文报道1例酸蚀症伴重度磨耗的病例，利用多模态数字化数据（口内扫描、面部扫描、电子面弓、下颌运动轨迹描记等）构建4D虚拟患者，制定全面的修复方案，进行不同牙齿的个性化微创修复，采用唇贴面、颊牙合贴面、牙合贴面、高嵌体、嵌体、全冠等多种修复体，完成数字化全牙列咬合重建治疗，为该疾病的诊治提供可视化、可全程质控的全局观诊疗策略。.
