In dental esthetic rehabilitation, patients pay great attention to the rehabilitative esthetic effect before teeth preparation, and this is also an important content of doctor-patient communication. Along with the development and combined application of intraoral scan, three-dimensional (3D) face scan, digital design, numerical control machining and 3D printing technology, digital technology is gradually applied to the virtual simulated design before irreversible operation in dental esthetic rehabilitation. Digital technology can be used in dentistry to simulate the esthetic outcome in advance, to assist communication among the dentists, patients and dental technicians, and to realize satisfactory outcome in the final restorations precisely, which, as a result, increases the clinical satisfaction. This review focuses on the application of digital virtual simulated design technology in dental esthetic rehabilitation, analyzes the current research development, deficiency and future prospects, so as to provide guidance for clinical diagnosis and treatment.
口腔美学修复中，修复后的美学效果是患者术前关注的重点，也是医患沟通的重要内容。随着口内扫描、面部扫描、数字化设计、数控切削和三维打印等技术的发展和联合应用，数字化技术逐步应用于口腔美学修复前的虚拟仿真设计，模拟修复后的美学修复效果，并用于医患、医技沟通，最后将患者满意的设计效果转移至最终修复体上，以提高患者对美学修复的满意度。本文对数字化虚拟仿真设计在口腔美学修复中的应用展开综述，分析其研究现状、不足以及发展方向，以期为临床诊疗提供参考。.
