TLDR
A subject-specific FEM of a rhesus macaque mandible was constructed, loaded and validated using in vivo data from the same animal, and the relative strain magnitudes were similar to those recorded in vivo for all strain locations.About:

Finite element analysis of individual taenioglossan radular teeth (Mollusca).
Wencke Krings,Jordi Marcé-Nogué,Jordi Marcé-Nogué,Jordi Marcé-Nogué,Hasan Karabacak,Matthias Glaubrecht,Stanislav N. Gorb +6 more
TL;DR: For the first time, a quantitative approach is used, Finite-Element-Analysis (FEA), to test hypotheses regarding the function of particular taenioglossan tooth types, and it is posited that the central and lateral teeth are best suitable for scratching substrate loosening ingesta, whereas the marginals are best suited for gathering food particles.

The use of extruded finite-element models as a novel alternative to tomography-based models: a case study using early mammal jaws.
Nuria Melisa Morales-García,Thomas D. Burgess,Jennifer J. Hill,Pamela G. Gill,Emily J. Rayfield +4 more
TL;DR: Extruded FE models constitute a viable alternative to the use of tomography-based 3D models, particularly in relatively flat bones, in Morganucodon and Kuehneotherium.

The Mechanical Effect of the Periodontal Ligament on Bone Strain Regimes in a Validated Finite Element Model of a Macaque Mandible.
TL;DR: The findings suggest that the mechanical importance of the PDL in FEMs of the mandible during chewing is dependent on the scope of the hypotheses being tested, and whether researchers are comparing strain gradients across species/taxa or if researchers are concerned with absolute strain values, sensitivity analysis is required.

Glucocorticoids cause mandibular bone fragility and suppress osteocyte perilacunar-canalicular remodeling.
A. Sean Alemi,Courtney M. Mazur,Courtney M. Mazur,Tristan W. Fowler,Jonathon J. Woo,P. Daniel Knott,Tamara Alliston,Tamara Alliston +7 more
TL;DR: Osteocyte PLR in the neural crest-derived mandible is susceptible to glucocorticoids, just as it is in the mesodermally-derived femur, highlighting the need to further study PLR as a target of drugs, and radiation in mandibular osteonecrosis.

Why ruminating ungulates chew sloppily: Biomechanics discern a phylogenetic pattern
Zupeng Zhou,Daniela E. Winkler,Josep Fortuny,Thomas M. Kaiser,Jordi Marcé-Nogué,Jordi Marcé-Nogué +5 more
TL;DR: Three-dimensional finite element analysis is used to assess the biomechanical performance of mandibles in eleven ungulate taxa with well-established but distinct dietary preferences and finds that mandibular morphologies reflect the masticatory demands of specific ingesta within the orders Artiodactyla and PerissodactylA.

Jaw muscle function and wishboning of the mandible during mastication in macaques and baboons
TL;DR: EMG data demonstrate that jaw-closing muscle recruitment patterns for macaques and baboons differ from those of humans, and it appears, based on previously published EMG data, that the human symphysis may also experience wishboning.
Journal ArticleDOI
Considerations for reporting finite element analysis studies in biomechanics.
TL;DR: The goal of this document is to identify resources and considerate reporting parameters for FEA studies in biomechanics that can establish an explicit outline of the decision-making process in simulation-based analysis for enhanced reproducibility, reusability, and sharing.

TL;DR: The objective was to develop an open-source and multi-platform framework to read, write, modify and visualize data from any motion analysis systems using standard (C3D) and proprietary file formats (used by many companies producing motion capture systems).

Elastic properties of human supraorbital and mandibular bone
TL;DR: Directional differences in both locations demonstrated that cranial bone was not elastically isotropic, and it is suggested that differences in elastic properties correspond to regional differences in function.
Journal ArticleDOI
Structural allometry of the prosimian mandibular corpus and symphysis
TL;DR: Data from the examined biomechanical scaling of corpus and symphysis dimensions was examined in prosimians and compared to anthropoids and strongly support previous predictions about structural and functional differences between the masticatory system of extant primate suborders.
