This study reviews the outcome of implant placement in 61 patients after augmentation of severely atrophic alveolar bone with a bovine bone mineral, Bio-Oss. Bone augmentation was performed at 4 different sites: alveolar crest width, alveolar crest height, antral cavity, or nasal cavity. After a mean healing time of 11.9 months, 231 implants were placed in Bio-Oss bone. The time of loading of the implants varied between 12 and 113 months. Calculated from the time of implant placement and irrespective of loading time, a survival rate of 80.5% for the individual implants was estimated. In most patients (73%), Bio-Oss was mixed with autogenous bone from the chin. However, the results indicated that autogenous bone may be excluded from the Bio-Oss graft.
本研究回顾了61例患者在使用牛骨矿物质Bio-Oss对严重萎缩性牙槽骨进行增量后种植体植入的结果。骨增量在4个不同部位进行:牙槽嵴宽度、牙槽嵴高度、上颌窦腔或鼻腔。平均愈合时间为11.9个月后,在Bio-Oss骨中植入了231颗种植体。种植体的加载时间在12至113个月之间。从种植体植入时间计算,且不考虑加载时间,单个种植体的存活率估计为80.5%。在大多数患者(73%)中,Bio-Oss与来自下巴的自体骨混合使用。然而,结果表明自体骨可能无需混入Bio-Oss移植物中。
