直接3D打印隐形矫治器的研究进展OA

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 thermocompres-sion methodologies,including the compromising of material properties,extensive production cycles,and substantial mate-rial 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 intro-duced;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.
