本文报道1例利用数字化技术辅助上前牙功能与美学再修复的病例。患者因既往烤瓷联冠修复后出现咬合不适、美学欠佳而就诊。经系统的美学与功能评估，结合数字化微笑设计（DSD）、电子面弓与口内扫描数据，通过精准分析咬合关系及牙体美学比例，制定出个性化修复方案。利用DSD美学预告优化医患沟通，明确治疗预期与风险；联合电子面弓与虚拟架技术，评估并调整临时冠切导角度，缓解下颌运动受限与咬肌疲劳症状；借助数字化扫描及计算机辅助设计与制作（CAD/CAM）技术，实现过渡性修复体精准复制，保障最终修复体在形态、色泽与功能上的协调统一。术后随访2年，患者对美学效果与咬合舒适度均感满意。本病例体现了数字化技术在复杂前牙修复中整合美学与功能、提高修复效果可预期性及长期稳定性等重要作用。

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.
