To established a digital workflow for stabilization occlusal splint with computer-aided design and computer-aided manufacturing (CAD/CAM) methods. Two subjects were enrolled from April 2019 to May 2019 from Department of Prosthodontics, Ninth People's Hospital, Shanghai Jiao Tong University School of Medicine (one male, 25 years old; one female, 24 years old). The working models of the participants' dentition were made. Two stabilization occlusal splints were manufactured for each participant using digital workflow and conventional workflow. With the digital workflow, the three-dimensional (3D) scanning of the cast, recording of the digital personalized mandibular movements and condyle trajectory, and the design and the 3D printing for the fabrication of the final appliance using CAD/CAM technologies were performed. With conventional workflow, conventional technologies were adopted based on requirements and experiment of designing and manufacturing of stabilization splint. During try-in, a checklist was built to compare the clinical performance of the two workflows. The digital workflow of the stabilization occlusal splint was built successfully. The total score of clinical primary evaluation by the two subjects were 26 and 26 for digital workflow splints, and 25 and 23 for conventional workflow splints. Digital stabilization occlusal splint workflow is feasible.
采用计算机辅助设计和计算机辅助制造（CAD/CAM）方法建立稳定咬合板的数字化工作流程。2019年4月至2019年5月，从上海交通大学医学院附属第九人民医院口腔修复科招募了两名受试者（一名25岁男性；一名24岁女性）。制作了受试者牙列的工作模型。使用数字化工作流程和传统工作流程为每位受试者制作了两个稳定咬合板。采用数字化工作流程时，对模型进行三维（3D）扫描，记录数字化个性化下颌运动和髁突轨迹，并使用CAD/CAM技术进行最终矫治器制作的设计和3D打印。采用传统工作流程时，根据稳定咬合板设计和制作的要求及实验采用传统技术。试戴期间，建立了一份检查表以比较两种工作流程的临床性能。成功建立了稳定咬合板的数字化工作流程。两名受试者对数字化工作流程咬合板的临床初步评估总分分别为26分和26分，对传统工作流程咬合板的评估总分分别为25分和23分。数字化稳定咬合板工作流程是可行的。
