摘要：

三维（3D）打印是一种高效的增材制造技术，已用于直接打印口腔正畸隐形矫治器。这一技术能够克服传统热压法带来的材料特性改变、工艺周期长、耗材量大等弊端，实现隐形矫治器的高精度和高效制造，提供温和持效的矫治力。本文介绍隐形正畸领域常见的直接3D打印技术以及用于3D打印隐形矫治器的打印材料，并从制造精度、力学性能、物化性能和生物相容性方面对3D打印隐形矫治器的性能进行分析。随着技术的不断发展，直接3D打印隐形矫治器有望为正畸人群提供更高效的正畸治疗方案。

Abstract:

Three-dimensional (3D) printing, an efficient and advanced additive manufacturing technology, enables the direct fabrication of clear aligners. This approach successfully addresses the limitations of conventional thermocompression methodologies, including the compromising of material properties, extensive production cycles, and substantial material wastage. Direct 3D printing clear aligners can achieve high-precision, rapid manufacturing while delivering gentle and sustained orthodontic forces. In this review, common 3D printing technologies in the field of oral healthcare are introduced; resin materials used for direct 3D printing of clear aligners are examined; and research progresses in terms of ma-nufacturing precision, mechanical performance, physical and chemical properties, and biocompatibility are explored. With the development and innovation of high-performance resins and 3D printing processing technology, 3D printing is expec-ted to provide simplified, efficient, and personalized treatment services to orthodontic patients, thereby introducing new opportunities and advancements to the field of oral medical engineering.

Key words: three-dimensional printing, clear aligners, orthodontic, printing process, mechanical property, biocompatibility
