This article reports the utilization of mandibular tori as an alternative source of autogenous bone for ridge augmentation and maxillary sinus lifting to facilitate ideal implant placement. A patient presenting bilateral mandibular tori required replacement of a missing maxillary molar and a mandibular premolar. Both areas showed ridge deficiency that required bone augmentation before implant placement. Mandibular tori were used for horizontal augmentation of the mandibular alveolar ridge and vertical augmentation of the maxillary ridge by elevation of the maxillary sinus. Adequate new bone formation was noted in both areas 6 months after grafting. Bone formed in the grafted areas showed comparable clinical features to those of native bone. Implants were successfully placed and loaded, restoring esthetics and function. Within the limitations of this observation, mandibular tori can be successfully used for ridge augmentation and sinus lifting. However, further controlled studies are needed to determine the overall benefit of this source of autogenous bone.
本文报道了利用下颌隆突作为自体骨的替代来源，用于牙槽嵴增高和上颌窦提升，以促进理想的种植体植入。一名双侧下颌隆突患者需要替换一颗缺失的上颌磨牙和一颗下颌前磨牙。这两个区域均显示牙槽嵴不足，在种植体植入前需要进行骨增量。通过上颌窦提升，下颌隆突被用于下颌牙槽嵴的水平增量和上颌嵴的垂直增量。移植后6个月，两个区域均观察到足够的新骨形成。移植区域形成的骨在临床特征上与天然骨相似。种植体成功植入并加载，恢复了美观和功能。在本观察的局限性范围内，下颌隆突可成功用于牙槽嵴增高和上颌窦提升。然而，需要进一步的对照研究来确定这种自体骨来源的总体益处。
