摘　　要：目的通过创建三维虚拟牙科患者,探索一套可行的数字化诊疗流程,辅助美学修复患者进行多学科的诊断和治疗。方法对需要进行美学修复的患者,将口外面部扫描、口内牙列扫描以及锥形束计算机断层扫描(CBCT)的数据进行处理和整合,创建三维虚拟牙科患者,并与现有的计算机辅助设计和计算机辅助制造(CAD/CAM)设备对接,实现美学修复中以面部轮廓和CBCT引导的,从数字化设计、预测到修复体加工的一整套数字化诊疗流程。结果成功建立了多学科合作解决前牙美学修复的数字化诊疗流程,通过创建三维虚拟牙科患者进行美学修复是可行的。结论创建三维虚拟牙科患者进行修复体设计和制作的全数字化诊疗流程,为解决复杂病例提供了一条新的临床路径,对于美学修复、种植手术、正颌手术和正畸治疗有重要的指导意义,能简化患者的治疗流程和就诊次数,从而提高治疗效果及患者满意度。Objective To explore a feasible digital workflow to enhance the multi-disciplinary diagnosis and treatment(MDT)by establishing three-dimensional(3D)virtual dental patients in esthetic restoration.Methods Patients in need of esthetic restoration in their anterior teeth were included in the study.Extra-oral facial scan,intra-oral scan,and cone beam computed tomography were integrated to establish 3D virtual dental patients,and were then connected with existing computer aided design and computer aided manufacturing equipment.Esthetic restoration was finished with a complete digital workflow to allow the digital design,outcome prediction,and fabrication of definitive restoration from a facial perspective.Results The complete digital workflow of esthetic restorations in MDT mode was successfully established.Esthetic restoration was made feasible through the establishment of 3D virtual dental patients.Conclusion The complete digital workflow undoubtedly provides a new clinical pathway for complicated cases.It is greatly significant for planning esthetic restoration,implant surgery,orthognathic surgery,and orthodontic treatment.The method is useful in reducing appointments and clinical procedures and in improving the therapeutic effect and patient satisfaction.
