The aim of this study was to evaluate the radiographic and histomorphometric results of two different xenografts in bilateral sinus augmentation in patients with posterior maxillary atrophy.
Eight patients with less than 5 mm residual alveolar bone height were included in this study. One side was augmented with bovine bone graft-1 and the other side with bovine bone graft-2. Radiographic analyses were performed before and after augmentation, and before the implant placement. After 8 months of healing period, bone biopsies were obtained during implant placement.
No statistically significant difference was found between the groups, based on post-augmentation and pre-implantation graft heights (P > .05). Histomorphometric evaluation demonstrated 24.63% and 29.13% newly formed bone in the graft-1 and graft-2 groups, respectively. Intergroup differences were not significant for the mean percentage of new bone formation (P > .05).
Within the limitations of this study, it can be concluded that xenograft materials resulted in satisfactory bone height and trabecular new bone formation, and they could be used for the rehabilitation of atrophic maxillae.
本研究旨在评估两种不同异种骨移植材料用于上颌后牙区骨萎缩患者双侧上颌窦提升术的影像学及组织形态计量学结果。
本研究纳入8例剩余牙槽骨高度不足5mm的患者。一侧使用牛骨移植材料1进行上颌窦提升，另一侧使用牛骨移植材料2。在骨增量前后及种植体植入前进行影像学分析。在8个月的愈合期后，于种植体植入时获取骨活检样本。
基于骨增量后及种植体植入前的移植骨高度，两组间未发现统计学显著差异（P > .05）。组织形态计量学评估显示，移植材料1组和移植材料2组的新生骨分别为24.63%和29.13%。两组间新生骨形成的平均百分比差异无统计学意义（P > .05）。
在本研究的局限性范围内，可以得出结论，异种骨移植材料可带来满意的骨高度及小梁新生骨形成，可用于萎缩性上颌骨的修复。
