Background:

Understanding the biomechanics of the masticatory system is crucial for dental and medical applications.
Previous studies often relied on simulations or limited experimental data.
Quantitative analysis of force-displacement in human skulls is essential for accurate modeling.

Purpose of the Study:

To analyze the force-displacement response of a dried human skull during simulated mastication.
To quantitatively assess load concentration and dissipation using advanced holographic techniques.
To provide data for validating finite element models of the masticatory system.

Main Methods:

Utilized Double-Exposure Photorefractive Holographic Interferometry (2E-PRHI) on a dried human skull.
Simulated isolated muscle contractions (SIC) to apply controlled loads.
Employed fringe analysis methods to derive quantitative force-displacement data.

Main Results:

Quantitatively documented the force-displacement response of the dried human skull under applied loads.
Identified patterns of load concentration and dissipation during simulated mastication.
Provided real biomechanical response data for the human skull.

Conclusions:

The study successfully quantified the biomechanical response of a dried human skull to masticatory forces.
2E-PRHI is a viable technique for analyzing complex biomechanical behaviors.
The results serve as valuable data for complementary studies, including finite element analysis.
