Abstract: The implantation in the aesthetic zone is often accompanied by bone augmentation surgery to acquire enough peri-implant bone volume. Meanwhile, bone augmentation may achieve greater contour morphology and lay a solid foundation for soft tissue aesthetic effects. The guided bone regeneration (GBR) is the most common bone augmentation surgery performed in the aesthetic zone and has a satisfactory clinical outcome. Considerable literatures have discussed the factors influencing the postoperative effects of GBR, including factors associated with patients and surgery. This review focuses on the patient-related local factors, summarizing the evidence about the anatomical characteristics of the alveolar bone. We discuss the relationship between the anatomical characteristics of the alveolar bone and postoperative outcome of GBR, including the morphology of alveolar bone defect, the initial bone volume, the blood supply of alveolar bone at the implant sites, and the characteristics of the extraction socket in immediate implant placement, to provide a reference for the treatment planning for patients with bone defects in the aesthetic area and for the long-term prognosis of GBR.

Key words: Guided bone regeneration, Aesthetic zone, Alveolar bone defect, Immediate implant placement
