The present article describes a step-by-step maximally digitalized workflow protocol with computer-aided design and computer-aided manufacturing (CAD/CAM) in partial-arch edentulous patients rehabilitated with fixed dental prostheses and removable partial dentures (FDPs and RPDs). Facial digitalization, intraoral scans, and functional mandibular movement recordings were used to create a 4D virtual patient on commercially available CAD software. The fixed components including post-and-cores, both metal-ceramic with extra-coronal attachment and monolithic zirconia crowns, and the RPDs were manufactured by computer numerical controlled direct milling. This innovative digital approach using the virtual patient and the superimposition of interim RPDs fitted in the mouth has been used to provide fixed and removable rehabilitation to the patient without clinical complications with 2 years of follow-up. Within the limitations of this report, the developed combined prosthesis fabrication technique allowed optimization of the production by decreasing the clinical steps and laboratory procedures in partial-arch edentulous rehabilitated with FDPs and RPDs.
本文描述了一种逐步实现最大化数字化的工作流程协议,该协议运用计算机辅助设计和计算机辅助制造(CAD/CAM)技术,为采用固定义齿和可摘局部义齿(FDPs和RPDs)修复的部分牙列缺失患者提供修复方案。通过面部数字化、口内扫描和功能性下颌运动记录,在商用CAD软件上创建4D虚拟患者模型。固定部件包括桩核、带有冠外附着体的金属烤瓷修复体和一体式氧化锆全冠,以及RPDs,均通过计算机数控直接铣削制造。这种利用虚拟患者以及口内试戴临时RPDs进行叠加的创新数字化方法,已用于为患者提供固定和可摘修复体,且经过2年随访无临床并发症。在本报告的局限性范围内,所开发的联合修复体制作技术通过减少采用FDPs和RPDs修复部分牙列缺失患者的临床步骤和实验室操作,实现了生产的优化。
