In the age of digital dentistry, virtual treatment planning is becoming an increasingly important element of dental practice. Thanks to new technological advances in the computer- assisted design and computer-assisted manufacturing (CAD/CAM) of dental restorations, predictable interdisciplinary treatment using the backward planning approach appears useful and feasible. Today, a virtual smile design can be used as the basis for creating an esthetic virtual setup of the desired final result. The virtual setup, in turn, is used to plan further treatment steps in an interdisciplinary team approach, and communicate the results to the patient. The smile design concept and the esthetic analyses required for it are described in this article. We include not only a step-by-step description of the virtual smile design workflow, but also describe and compare the several available smile design options and systems. Subsequently, a brief discussion of the advantages and limitations of virtual smile design is followed by a section on different ways to integrate a two-dimensional (2D) smile design into the digital three-dimensional (3D) workflow. New technological developments are also described, such as the integration of smile designs in digital face scans, and 3D diagnostic follow-up using intraoral scanners.
在数字牙科时代，虚拟治疗计划正日益成为牙科实践的重要组成部分。得益于牙科修复体计算机辅助设计和计算机辅助制造（CAD/CAM）方面的新技术进展，采用逆向规划方法进行可预测的多学科治疗显得有用且可行。如今，虚拟微笑设计可作为创建预期最终结果的美学虚拟模型的基础。反过来，虚拟模型用于以多学科团队方式规划进一步的治疗步骤，并将结果传达给患者。本文介绍了微笑设计概念及其所需的美学分析。我们不仅包括虚拟微笑设计工作流程的逐步描述，还描述并比较了几种可用的微笑设计选项和系统。随后，简要讨论了虚拟微笑设计的优点和局限性，接着是关于将二维（2D）微笑设计整合到数字三维（3D）工作流程的不同方法的部分。还介绍了新技术发展，如将微笑设计整合到数字面部扫描中，以及使用口内扫描仪进行3D诊断随访。
