美学区牙列对于咀嚼、发音和美观等功能至关重要，传统的美学修复技术基于诊断蜡型制作诊断饰面或临时修复体来呈现治疗效果，需要医师、技师和患者三方配合，花费时间较多。随着数字化技术的发展，"虚拟患者"技术应运而生。借助静态虚拟患者技术，避免了传统技术中印模制取时可能带来的不适、诊断蜡型在运输过程中可能的损坏、患者对设计不满意时的反复修改和复诊等问题，有效提高了患者的满意度。在静态虚拟患者的基础上加入下颌运动轨迹数据和面部动态数据，可以获得更适合患者的前牙舌面、切端及唇面的形态和位置，减少临床调操作时间和难度，降低干扰、创伤、崩瓷和修复体脱落等风险，提高修复的美学和咬合功能效果。目前，虚拟患者技术所需设备数量多，成本高，精度、文件格式不统一，操作技术敏感性高，配准流程复杂等，使其使用受到一定限制。未来如能开发出一站式完成虚拟患者所需数据的采集技术，并基于人工智能技术自动完成多源数据的配准，将进一步推动虚拟患者技术的普及。

The dentition in the aesthetic area is crucial for functions such as chewing, pronunciation, and aesthetics. Traditional aesthetic restoration techniques are based on diagnostic wax-up to create diagnostic mock-ups or temporary restorations to present therapeutic outcomes, which requires the cooperation of dentists, technicians, and patients, and takes a considerable amount of time. With the development of digital technology, the "virtual patient" technology has emerged. With the aid of the static virtual patient technique, possible problems, such as discomfort during impression in traditional techniques, damage to diagnostic wax-up during transportation, and repeated modifications and visits when patients are dissatisfied with the design, have been avoided, and patient satisfaction is effectively improved. By attaching mandibular movement trajectory data and facial dynamic data, the morphology and position of the incisor edge and lingual and labial surfaces of the anterior teeth are more suitable for the patients. This reduces the time and difficulty of occlusal adjustment in the clinic, lowers the risks of occlusal interference, occlusal trauma, porcelain breaking, or restoration detachment, and improves the aesthetic and occlusal function of the restorations. Nowadays, the virtual patient technology requires a large number of devices with high costs, inconsistent accuracy, and file formats, high technical sensitivity, and sophisticated registration processes, etc. Its application is still subject to certain limitations. If the collection of data required for virtual patients can be completed on a single device, and the function of automatically registering multi-source data can be accomplished with artificial intelligence technology in the future, it will greatly popularize the technology for virtual patients.
