Introduction:
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.
Materials And Methods:
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.
Results:
The fracture threshold mean resection height was 19.33 mm with a percentage of error of 6.72%.
Discussion:
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.
