Abstract: Alveolar ridge defects are often caused by periodontitis，trauma，and tumor，etc. Adequate alveolar bone is a prerequisite for good clinical outcomes and long-term prognosis after implantation.Therefore，effective repair and regeneration of alveolar bone has great significance for reconstruction of oral function. The commonly used bone augmentation techniques include guided bone regeneration，Onlay bone grafting，alveolar bone grafting， maxillary sinus floor elevation and so on. The development of digital technology enables alveolar bone augmentation to achieve precise and minimally invasive effect. This paper mainly reviews the research progress of application of digital technology in alveolar bone augmentation.

Key words: alveolar augmentation, digital technology, computer aided design and computer aided manufacturing, 3D printing
