Osseointegration is critical for the success of dental implants. Surface modifications of dental implants play a crucial role in enhancing osseointegration and implant stability. This in-vitro study aims to evaluate the influence of various surface modifications on dental implant stability.
Dental implants with different surface modifications were prepared and subjected to in-vitro testing. Surface modifications included sandblasting, acid etching, and plasma spraying. Implant stability was assessed using resonance frequency analysis (RFA) and pull-out tests. Statistical analysis was performed to compare the stability of implants with different surface modifications.
The results showed that implants with sandblasted and acid-etched surfaces exhibited significantly higher stability compared with those with only a machined surface. The mean RFA values for sandblasted and acid-etched implants were 75 ± 5 and 80 ± 6, respectively, whereas machined implants recorded a mean RFA value of 60 ± 4. Similarly, pull-out tests demonstrated higher maximum tensile strengths for sandblasted and acid-etched implants compared with machined implants.
Surface modifications, such as sandblasting and acid etching, significantly enhance dental implant stability . These modifications promote better osseointegration, which is crucial for the long-term success of dental implants in clinical practice.
骨结合对于牙种植体的成功至关重要。牙种植体的表面改性在增强骨结合和种植体稳定性方面起着关键作用。本体外研究旨在评估各种表面改性对牙种植体稳定性的影响。
制备具有不同表面改性的牙种植体并进行体外测试。表面改性包括喷砂、酸蚀和等离子喷涂。使用共振频率分析（RFA）和拔出试验评估种植体稳定性。进行统计分析以比较具有不同表面改性的种植体的稳定性。
结果表明，与仅经过机械加工表面的种植体相比，具有喷砂和酸蚀表面的种植体表现出明显更高的稳定性。喷砂和酸蚀种植体的平均RFA值分别为75±5和80±6，而机械加工种植体的平均RFA值为60±4。同样，拔出试验表明，与机械加工种植体相比，喷砂和酸蚀种植体具有更高的最大拉伸强度。
喷砂和酸蚀等表面改性可显著提高牙种植体稳定性。这些改性促进更好的骨结合，这对于牙种植体在临床实践中的长期成功至关重要。
