OBJECTIVES
The aims of this in vitro study were to evaluate reliability of the Osstell and Periotest devices in the assessment of implant stability and to perform a method comparison.
MATERIAL AND METHODS
Commercial dental implants were inserted into bovine rib segments of different anatomical origins and densities. Repeated measurements were performed, varying (a) the torque-in force of the devices' attachment screw (the Osstell transducer and the ball attachment, insert for the Periotest device), (b) the insertion site bone quality, and (c) the thread exposure in simulated peri-implant bone defects.
RESULTS
Both methods were comparably reliable and showed a strong association to each other in the classification of implant stability. As opposed to torque-forced screw attachment, the variations in bone composition, differences in inter-implant stability of adjacent implants, and peri-implant bone reduction were statistically significant for both methods.
CONCLUSIONS
Both non-invasive diagnostic devices seem to be useful in the long-term follow-up of implant integration.
目的
本体外研究旨在评估Osstell和Periotest设备在评估种植体稳定性方面的可靠性，并进行方法比较。
材料与方法
将商用牙科种植体植入不同解剖来源和密度的牛肋骨段。进行重复测量，改变（a）设备附着螺钉（Osstell传感器和球附着，Periotest设备的插入件）的扭矩力，（b）植入部位的骨质量，以及（c）模拟种植体周围骨缺损中的螺纹暴露情况。
结果
两种方法具有相当的可靠性，并且在种植体稳定性分类中彼此显示出很强的相关性。与扭矩强制螺钉附着相反，两种方法在骨成分变化、相邻种植体之间种植体稳定性差异以及种植体周围骨减少方面均具有统计学意义。
结论
两种非侵入性诊断设备似乎都有助于种植体整合的长期随访。
