【摘要】 牙槽骨骨量严重不足的患者需在种植前行骨增量手术，其成功与否取决于骨增量材料的稳定性和骨再生空间的维持能力。支架材料为骨再生提供了空间结构和成骨环境，对骨增量的效果至关重要。随着计算机辅助设计和计算机辅助制造的发展，不同材料制备的3D打印个性化支架应运而生。本文针对不同材料制造的3D打印个性化支架进行综述，讨论了钛网、聚醚醚酮网以及可吸收高分子复合支架材料的特性与应用，评价应用效果和未来发展方向。更多还原

【Abstract】 Patients with severe bone mass deficiencies require bone augmentation surgery prior to implantation, and the success depends on the stability of the bone graft material and the ability to maintain the bone regeneration space. The scaffolds provide the spatial structure and osteogenic environment for bone regeneration, which are critical to the effect of bone augmentation. With the development of computer-aided design and computer-aided manufacturing, 3D printed individualized scaffolds prepared from different materials have emerged. In this paper, the characteristics and applications of titanium mesh, polyetheretherketone mesh and absorbable polymer composite scaffold materials are discussed, and the application effects and future development directions are evaluated.更多还原
