Area of Science:

Biomechanical Engineering
Dental Materials Science
Surgical Simulation

Background:

Mandibular fractures pose significant clinical challenges.
Accurate biomechanical models are crucial for understanding fracture mechanics.
Existing models may lack precision in simulating masticatory forces.

Purpose of the Study:

To validate a novel experimental model for assessing synthetic mandible fracture thresholds.
To evaluate the reproducibility of a simulated masticatory force device.
To establish a reliable protocol for future research on mandibular biomechanics.

Main Methods:

Five synthetic mandibles underwent progressive bone resection on both sides.
Simulated static chewing exercises were performed after each resection.
The fracture threshold was recorded to assess model reproducibility.

Main Results:

The mean resection height at the fracture threshold was 19.33 mm.
The experimental model exhibited a low percentage of error (6.72%).
Results demonstrated high consistency and reliability of the model.

Conclusions:

The validated experimental model offers a reproducible method for studying mandible biomechanics.
The low error rate supports the model's efficacy in simulating fracture thresholds.
Future applications include testing fresh mandibles and comparing with finite element models.
