The purpose of this study was to validate an experimental model of weakened synthetic mandible loaded in a device simulating masticatory forces by studying the reproducibility of the fracture threshold.
Both sides of five synthetic mandibles were weakened by progressive synthetic bone resection. The synthetic mandibles were submitted, after each resection, to static chewing exercises in the simulator. The threshold fracture was recorded.
The fracture threshold mean resection height was 19.33 mm with a percentage of error of 6.72%.
The low percentage of error allowed us to validate this experimental model. A comparison with other experimental or finite element models confirmed our protocol and results. We plan to apply this protocol to fresh weakened mandibles.
本研究的目的是通过研究骨折阈值的可重复性，验证在模拟咀嚼力的装置中加载的弱化合成下颌骨的实验模型。
通过渐进性合成骨切除术削弱五个合成下颌骨的两侧。每次切除后，将合成下颌骨在模拟器中进行静态咀嚼练习。记录骨折阈值。
骨折阈值的平均切除高度为19.33毫米，误差百分比为6.72%。
低误差百分比使我们能够验证该实验模型。与其他实验或有限元模型的比较证实了我们的方案和结果。我们计划将该方案应用于新鲜的弱化下颌骨。
