Two different techniques of vertical bone augmentation were compared to apply them to immunocompromised patients. One of them used autogenous bone graft; the other used xenograft. Thirty patients were involved in the study. Fifteen received autogenous ring shape grafts harvested from the mental region, and 15 received xenograft vertical tunnel augmentation. They have a total of 60 implants placed in the posterior region of the mandible (2 for each patient). Fixed full ceramic crowns were delivered. Two-year follow-up appointments after implant placement were made. Both autogenous bone grafts and xenografts showed similar long-term clinical regeneration outcome of vertical bone defects. Using autogenous bone rings simultaneously fixed by dental implants, the total treatment time and cost were shortened, but the traumatic reactions and complication rates were higher when compared to xenograft vertical tunnel augmentation. Due to the less traumatic character of the procedure, smaller complication rates and higher safety for the patients receiving chronic immunosuppression should avoid bone block augmentation and reap the benefits from vertical tunnel bone augmentation using xenograft materials.
比较了两种不同的垂直骨增量技术，以将其应用于免疫功能低下的患者。其中一种使用自体骨移植；另一种使用异种移植物。30名患者参与了该研究。15名患者接受了从颏部采集的自体环形移植物，15名患者接受了异种移植物垂直隧道增量术。他们在下颌骨后部共植入了60颗种植体（每位患者2颗）。安装了固定全瓷冠。在种植体植入后进行了两年的随访预约。自体骨移植和异种移植物在垂直骨缺损的长期临床再生结果方面显示相似。使用由牙种植体同时固定的自体骨环，总治疗时间和成本缩短，但与异种移植物垂直隧道增量术相比，创伤反应和并发症发生率更高。由于该手术创伤较小，并发症发生率较低，对于接受慢性免疫抑制的患者，更高的安全性应避免骨块增量，并从使用异种移植材料的垂直隧道骨增量术中获益。
