Large defects of jaw caused by tumor, trauma and so on in oral and maxillofacial region lead to facial deformity, language and chewing dysfunction, which severely damage the patient's life quality. Three-dimensional printing (3DP) is also named additive manufacturing (AM), which can print materials layer by layer to create three-dimensional objects. The complex shape of jaw defects can be accurately reconstructed using 3DP scaffold combined with image data, computer-aided-design and manufacture. It has specific advantages compared with traditional way of jaw reconstruction and has attracted much attention in the field of jaw tissue engineering recently. This article presented the progress of 3DP scaffold and its application in jaw reconstruction, providing a new idea for jaw reconstruction.
口腔颌面部肿瘤、外伤等常造成大范围的颌骨缺损，导致患者面部畸形、语言和咀嚼功能障碍等，严重影响患者生活质量。三维打印（3DP），又名“增材制造”，是一类将材料逐层添加来制造三维物体的技术。利用三维打印并结合影像数据、计算机设计和个性化制造颌骨修复支架，可以对复杂形态的颌骨缺损进行精确的修复重建，相对于传统的颌骨修复方式具有独特的优势，成为近年来颌骨组织工程支架研究的热点。本文就三维打印颌骨支架在颌骨修复中的应用作一综述，为临床上颌骨缺损的修复提供新思路。.
