摘要

导言:种植体周围炎是牙科种植中的一种严重并发症,如果不及时治疗,可能会导致种植体脱落和全身性疾病。种植体周围炎导致的骨缺损的有效再生对保持种植牙的功能至关重要。研究目的:本研究旨在比较细颗粒牙本质和 Bio-Oss 在重建种植体周围炎引起的骨缺损方面的效果。材料和方法:研究包括对骨密度随时间变化的综合放射学评估。骨密度的评估采用 Hounsfield 单位(HUs)作为骨衰减的衡量标准,在愈合过程中每隔 8 周和 12 周进行一次放射学评估。这项研究的参与者年龄从 30 岁到 65 岁不等。57 名患者被分为三组:22 名接受小颗粒牙本质治疗,15 名接受 Bio-Oss 治疗,20 名接受无骨替代材料治疗。结果显示细颗粒牙本质组在 8 周后骨密度增加了 20%(P < 0.05),而 Bio-Oss 组在 12 周后增加了 15%(P < 0.05)。对照组的骨密度变化极小(12 周后为 5%),无统计学意义。临床评估显示,细牙本质组的成功整合率为 95%,Bio-Oss 组为 85%,对照组为 70%。精细牙本质组在 8 周后骨密度增加了 20%(P < 0.05),而 Bio-Oss 组在 12 周后增加了 15%(P < 0.05)。对照组的骨密度变化极小(12 周后为 5%),无统计学意义。临床评估显示,精细牙本质组的成功整合率为 95%,Bio-Oss 组为 85%,对照组为 70%。结论:与对照组相比,细颗粒牙本质和 Bio-Oss 都能明显改善骨密度。细颗粒牙本质的初期再生速度快,适合立即进行骨再生,而 Bio-Oss 能提供长期支持,是在较长时间内保持种植体稳定性的理想选择。研究结果凸显了根据临床情况选择合适的骨替代材料对改善患者种植牙后的治疗效果的重要性。

Evaluation of Peri-Implantitis Bone Defect Healing: Comparing the Efficacy of Small-Particle Dentin and Bio-Oss in Bone Density Attenuation
Introduction: Peri-implantitis is a serious complication in dental implantology that, if left untreated, may lead to implant loss and systemic diseases. Effective regeneration of bone defects resulting from peri-implantitis is crucial to maintaining the functionality of dental implants. Purpose of the Study: The study aimed to compare the effectiveness of fine-particle dentin and Bio-Oss in the reconstruction of bone defects caused by peri-implantitis. Materials and Methods: The study included a comprehensive radiological assessment of changes in bone density over time. Bone density was assessed using Hounsfield Units (HUs) as a measure of bone attenuation, with radiological assessments performed at 8- and 12-week intervals during the healing process. The study included participants ranging in age from 30 to 65 years. Fifty-seven patients were divided into three groups: 22 patients received small-particle dentin, 15 received Bio-Oss, and 20 controls without bone substitute material. Results: The fine-dentin group showed a 20% increase in bone density after 8 weeks (p < 0.05), while the Bio-Oss group showed a 15% increase after 12 weeks (p < 0.05). The control group showed minimal changes in bone density (5% after 12 weeks), which was not statistically significant. Clinical evaluations showed 95% successful integration in the fine dentin group, 85% in the Bio-Oss group, and 70% in the control group. The fine-dentin group showed a 20% increase in bone density after 8 weeks (p < 0.05), while the Bio-Oss group showed a 15% increase after 12 weeks (p < 0.05). The control group showed minimal changes in bone density (5% after 12 weeks), which was not statistically significant. Clinical evaluations showed 95% successful integration in the fine-dentin group, 85% in the Bio-Oss group, and 70% in the control group. Conclusions: Both fine-particle dentin and Bio-Oss significantly improved bone density compared to the control group. Fine-particle dentin is suitable for immediate bone regeneration due to its rapid initial regeneration, while Bio-Oss provides long-term support, ideal for maintaining implant stability over a longer period of time. The results highlight the importance of selecting appropriate bone replacement materials depending on the clinical scenario to improve patient outcomes after dental implant placement.
