Abstract: Reconstruction of vertical bone defects presents a significant challenge in oral implantology，requiring surgical plans to be tailored based on the anatomical features of defect region. Based on clinical experience，this article analyzes the typical features of vertical bone defects in the maxillary anterior region，maxillary posterior region，and mandibular posterior region. It discusses the indications and key points of surgical procedures of the＂autogenous bone priority＂ strategy and 3D-printed individualized titanium mesh-supported guided bone regeneration technique. The aim is to provide clinical guidance for selecting vertical bone augmentation regimens based on anatomical region，and to promote the development of a systematic diagnosis and treatment guideline for vertical bone augmentation.

Key words: vertical bone defect, alveolar bone augmentation, guided bone regeneration, 3D-printed individualized titanium mesh

摘要： 垂直骨缺损重建是口腔种植修复领域中的重大挑战，需结合缺损部位的解剖特点对手术方案进行个体化设计。文章基于临床实践经验，分别分析上颌前牙区、上颌后牙区及下颌后牙区常见垂直骨缺损特点，探讨自体骨优先策略及3D打印个性化钛网支撑的引导骨再生等技术适应证与操作要点，旨在为不同解剖部位垂直骨增量方案的选择提供临床参考，以期推动垂直骨增量系统化诊疗指南的制定。
