In patients with insufficient bone height and width, the successful placement of dental implants is difficult with regards to maintaining an ideal pathway and avoiding important anatomical structures. Vertical and/or horizontal ridge augmentation may be necessary using various bone substitute materials and bone graft procedures. However, effective one-wall reconstruction has been challenging due to its poor blood supply and insufficient graft stability. In this paper, the authors summarize current evidence-based literature based on the author's clinical experience. Regarding bone substitutes, it is advantageous for clinicians to select the types of bone substitutes including autogenous bone. The most important consideration is to minimize complications through principle-based ridge augmentation surgery. Ridge augmentation should be decided with complete consent of the patients due to the possible disadvantages of surgery, complications, and unpredictable prognosis.
对于骨高度和宽度不足的患者，在维持理想植入路径和避免重要解剖结构方面，成功植入牙科种植体存在困难。可能需要使用各种骨替代材料和骨移植手术进行垂直和/或水平牙槽嵴增高。然而，有效的单壁重建一直具有挑战性，因为其血供较差且移植稳定性不足。在本文中，作者根据临床经验总结了当前基于证据的文献。关于骨替代物，临床医生选择包括自体骨在内的骨替代物类型是有利的。最重要的考虑是通过基于原则的牙槽嵴增高手术将并发症降至最低。由于手术可能存在的缺点、并发症和不可预测的预后，牙槽嵴增高应在患者完全同意的情况下决定。
