Although various techniques for the treatment of an atrophic alveolar ridge have been described in the literature, these procedures have increased the morbidity and discomfort for the patient. The purpose of this study was to evaluate histological and clinical results in 9 patients who underwent a subperiosteal tunneling procedure with a Bio-Oss block onlay graft in an atrophic area of the mandible.
Nine months after grafting, at the time of dental implantation, biopsy samples were taken from the grafted areas of 9 patients and were analyzed histologically.
New bone formation through the bovine bone block was observed consistently in the 9 cases. There was direct deposition of bone on the surface of the graft material.
The results of this study indicated that ridge augmentation using a subperiosteal tunneling procedure with Bio-Oss bone blocks might be useful for implant placement in the atrophic alveolar ridges.
尽管文献中已经描述了各种治疗萎缩牙槽嵴的技术，但这些方法增加了患者的发病率和不适感。本研究的目的是评估 9 例患者在颏下骨隧道下使用 Bio-Oss 块状骨移植的组织学和临床结果。
在移植后 9 个月，即种植牙时，从 9 例患者的移植部位取出活检样本进行组织学分析。
9 例患者的牛骨块均出现新骨形成。移植物表面有直接的骨沉积。
本研究结果表明，在萎缩的牙槽嵴中使用颏下骨隧道下 Bio-Oss 骨块进行牙槽嵴增高术可能有助于种植体的植入。
