The aim of this study was to compare the effectiveness of two bone substitute materials for socket preservation after tooth extraction. Extraction sockets in 10 patients were filled with either inorganic bovine bone material (Bio-Oss) or with synthetic material consisting of hydroxyapatite and silicon dioxide (NanoBone). Extraction sockets without filling served as the control. The results demonstrate the effectiveness of the presented protocol for socket preservation and that the choice of a suitable bone substitute material is crucial. The dimensions of the alveolar ridge were significantly better preserved with Bio-Oss than with NanoBone or without treatment. Bio-Oss treatment resulted in better bone quality and quantity for successful implant placement.
本研究的目的是比较两种骨替代材料在拔牙后牙槽窝保存中的有效性。10名患者的拔牙窝分别填充无机牛骨材料(Bio-Oss)或由羟基磷灰石和二氧化硅组成的合成材料(NanoBone)。未填充的拔牙窝作为对照。结果表明了所提出的牙槽窝保存方案的有效性,并且选择合适的骨替代材料至关重要。与NanoBone或未治疗相比,Bio-Oss能显著更好地保存牙槽嵴的尺寸。Bio-Oss治疗为成功植入种植体带来了更好的骨质量和骨量。
