Abstract

PURPOSE

To evaluate the micromobility of dental implants under occlusal loading in relation to stability measurements of resonance frequency analysis and insertion torque.

MATERIALS AND METHODS

The sample comprised of 24 implants inserted in 12 fresh cow ribs. Insertion torque and Osstell implant stability quotient (ISQ) measurements were recorded. An "ad hoc" acrylic premolar was made on a temporary abutment and screwed to each implant, and a force of 100 N was subsequently applied at an angle of 6 degrees. Implant micromotion was measured using a Questar microscope with a resolution of 2 μm and an image analysis program.

RESULTS

Data show a statistically significant inverse correlation between the ISQ values and implant micromotion under a load of 100 N (R = 0.86, P < 0.0001). The same relationship is found between insertion torque and implant micromotion, although the relationship is linear up to 34 N·cm and becomes exponential for higher values (R = 0.78, P < 0.0001). A direct correlation is established between insertion torque and ISQ values.

CONCLUSION

There is an inverse relationship between both ISQ and insertion torque values and implant micromotion under a load of 100 N.

摘要

目的

评估在咬合负载下牙种植体的微移动情况，并将其与共振频率分析和植入扭矩的稳定性测量结果相关联。

材料与方法

样本包括植入12根新鲜牛肋骨中的24颗种植体。记录植入扭矩和Osstell种植体稳定性商数（ISQ）测量值。在临时基台上制作一个“特制”丙烯酸前磨牙并拧到每个种植体上，随后以6度角施加100 N的力。使用分辨率为2μm的Questar显微镜和图像分析程序测量种植体的微动。

结果

数据显示，在100 N负载下，ISQ值与种植体微动之间存在统计学上显著的负相关（R = 0.86，P < 0.0001）。在植入扭矩与种植体微动之间也发现了相同的关系，尽管这种关系在扭矩达到34 N·cm之前是线性的，对于更高的值则变为指数关系（R = 0.78，P < 0.0001）。植入扭矩与ISQ值之间建立了直接相关性。
