通过Osstell (R)装置采用共振频率分析方法测量种植体的稳定性。本研究的目的是评估方向依赖的Osstell (R)传感器的作用。为此，采用了一套参数化有限元分析方法。当换能器绕垂直轴旋转时，关键的现象是系统行为的变化，这种变化发生在与肺泡嵴长轴30度至80度之间的位置。从所提供的结果看来，当近似垂直于这个长轴测量时，与理想垂直位置的偏差不得超过30度。在这种情况下，记录第一共振频率。在与牙槽嵴长轴近似平行的位置测量时，记录第二次共振频率。与理想平行位置的偏差不得超过10度。这些值与以前的值不能比较。(c) 2009年度。Elsevier Ltd.出版。版权所有。
Stability of dental implants is measured by means of the Osstell (R) device using a method of resonance frequency analysis. The aim of the study was to evaluate the role of direction-dependence of the Osstell (R) transducer. For this purpose, a set of parametrical finite element analyses has been used.When rotating the transducer around the vertical axis the crucial phenomenon is the change in behavior of the system, which occurs in positions between 30 degrees and 80 degrees to the long axis of the alveolar crest. It seems from the presented results that, when measuring approximately perpendicularly to this long axis, the deviation from the ideal perpendicular position must not exceed 30 degrees. In this case, the first resonance frequency is recorded. When measuring in the approximately parallel position to the long axis of the alveolar crest, the second resonance frequency is recorded. The deviation from the ideal parallel position must not exceed 10 degrees. These values are not comparable with the previous ones. (C) 2009 IPEM. Published by Elsevier Ltd. All rights reserved.
