Application of digital technology in the repair of functional and aesthetic defects in patients with acid erosion and severe attrition:a case report
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 de-fects can compromise aesthetics,phonetics,and mastica-tory 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 ve-neers,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 visual-ization and comprehensive quality control throughout the process.
