[摘要]随着种植外科的进展，大量垂直向和水平向骨增量技术得到发展。许多种植患者存在垂直向骨量不足的问题，需要增加垂直向骨量，但垂直向骨增量相对于水平向骨增量难度比较大，预见性较差，往往易致较多的并发症，因此，垂直向骨增量技术受到了越来越多的关注。引导骨再生技术和牵张成骨术是2类较常用的垂直向骨增量技术，在临床上已得到一定的应用，本文将对其在垂直向骨增量上作一综述。

    [Abstract]Numerous surgical procedures concerning vertical and horizontal bone augmentation emerge with the rapid development of dental implant surgery. Many patients have the problem of vertical bone deficiency, however, compared to horizontal bone augmentation, vertical bone augmentation is more complex and unpredictable and in-duces more complications. Therefore, vertical bone augmentation gains increased attention in both clinical and ba-sic research field. Distraction osteogenesis and guided membrane regeneration are two commonly conducted vertical bone augmentation surgical procedures under intensive investigation. In this review, we evaluated these two proce-dures in a clinical perspective and evaluated them according to their augmentation efficiency, bone resorption and implantation success. ......
