CAD/CAM complete dentures have increased in popularity and a wide variety of systems are currently available. These prostheses present many advantages for clinicians, technicians and patients. Subtractive manufacturing is used by most of the available systems while a few manufacturers use an additive manufacturing technique. This article describes the currently available systems and materials available for the fabrication of CAD/CAM complete dentures and reviews the literature relative to their physical properties.
A comprehensive review of the literature was completed to enumerate the currently available techniques to fabricate CAD/CAM complete dentures and discuss their physical properties. A search of English language peer-reviewed literature was undertaken using MEDLINE and PubMed on research articles published between 2000 and 2019. A hand search of relevant dental journals was also completed.
The literature indicates the physical properties of CAD/CAM milled poly(methylmethacrylate) or PMMA as it is commonly described is superior to conventionally processed PMMA for the fabrication of complete dentures.
The incorporation of CAD/CAM technology into complete denture design and fabrication streamlines the clinical and laboratory processes and provides improved physical properties that enhance denture quality.
CAD/CAM 全口义齿的应用日益普及，目前有多种系统可供选择。这些义齿为临床医生、技师和患者带来了许多优势。大多数现有系统都采用减法制造工艺，而少数制造商则使用加法制造技术。本文介绍了目前可用于制作 CAD/CAM 全口义齿的系统和材料，并综述了与其物理性能相关的文献。
通过综合文献回顾，列举了目前可用于制作 CAD/CAM 全口义齿的技术，并讨论了它们的物理性能。使用 MEDLINE 和 PubMed 数据库，检索了 2000 年至 2019 年期间发表的关于研究文章的英文同行评议文献，并对手头相关牙科期刊进行了手工搜索。
文献表明，与传统加工的 PMMA 相比，CAD/CAM 铣削聚甲基丙烯酸甲酯（PMMA）或通常所说的 PMMA 的物理性能更优，适用于全口义齿的制作。
将 CAD/CAM 技术应用于全口义齿设计和制作中，简化了临床和实验室流程，并提供了改善的物理性能，从而提高了义齿质量。
