The accurate reproduction of the form and surface details of missing body structures is an essential part of any successful prosthetic rehabilitation. It helps mask the prosthesis and gives confidence to the patient. This clinical report details the integration of multiple in-house digital technologies of laser scanning, rapid prototyping, and digital color scanning and formulating to improve the shape, texture, orientation, and color of auricular prostheses for 3 patients with missing unilateral ears. A structured light laser scanner was used to digitize the patient's nondefect ear. The digitized data were then manipulated in specialist software and mirrored to reflect the opposing side. A rapid prototyping machine was used to manufacture a 3-dimensional (3D) model of the soft tissue required. This 3D mirrored ear model allowed the accurate reproduction of missing soft tissue. A color spectrometer was used to accurately reproduce the skin tones digitally and physically.
精确再现缺失身体结构的形态和表面细节是任何成功的假体康复的重要组成部分。它有助于掩盖假体并增强患者的信心。本临床报告详细介绍了多种内部数字技术的整合，包括激光扫描、快速成型、数字颜色扫描和配方制定，以改善3例单侧耳缺失患者的耳廓假体的形状、质地、方向和颜色。使用结构光激光扫描仪对患者的非缺损耳进行数字化处理。然后在专业软件中对数字化数据进行处理并镜像以反映对侧。使用快速成型机制造所需软组织的三维（3D）模型。这个3D镜像耳模型能够精确再现缺失的软组织。使用分光计在数字和物理上精确再现肤色。
