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.

Key words: 3D printing, Alveolar bone augmentation, Individualized scaffolds
