This case report described the functional and aesthetic rehabilitation of anterior teeth using digital techniques. The patient complained of aesthetic dissatisfaction and occlusal discomfort following previous porcelain-fused-to-metal union crowns. Comprehensive functional and aesthetic evaluations were conducted utilizing digital smile design (DSD), electronic facebow, and intraoral scanning, so as to analyze occlusal relationships and tooth aesthetic proportions, allowing for the development of an individualized treatment plan. DSD was used for aesthetic preview and effective patient communication, clarifying expectations and potential risks. The electronic facebow and virtual articulator facilitated the adjustment of the incisal guidance of the provisional crown, alleviating mandibular movement limitations and masseter fatigue. CAD/CAM and intraoral scanning enabled precise replication of provisional restorations and ensured optimal harmony in contour, shade, and function for the final prostheses. After two years of follow-up, the patient reported satisfaction with both esthetic outcome and occlusal comfort. This case highlighted the critical role of digital techniques in integrating aesthetics and function, enhancing predictability and ensuring long-term stability in complex anterior restorations.
