Defects in the facial region can be treated with maxillofacial prostheses; however, fabrication of the prosthesis is a time-consuming process. The short lifetime of silicone material due to inherent deterioration has stimulated a search for more practical methods. This case report involves a semidigital workflow for replacement of an ear prosthesis. The existing contralateral intact ear and retentive bar of the existing prosthesis were scanned using an intraoral scanner. Resin models of the bar and the mirror image of the ear were fabricated using a 3D printer, and wax replicas were obtained using silicone impression material. This method was successful, time-saving, and comfortable for the clinician and patient.
面部区域的缺损可用颌面修复体进行治疗；然而，修复体的制作是一个耗时的过程。由于固有老化导致硅酮材料使用寿命短，促使人们寻找更实用的方法。本病例报告涉及一种用于更换耳部修复体的半数字化工作流程。使用口内扫描仪对现有的对侧完整耳朵和现有修复体的固位杆进行扫描。使用3D打印机制作固位杆的树脂模型和耳朵的镜像模型，并使用硅酮印模材料获得蜡复制品。这种方法是成功的，节省时间，并且对临床医生和患者来说都很舒适。
