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.
Journal ArticleDOI
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.

Functional Correlates of Fiber Architecture of the Lateral Caudal Musculature in Prehensile and Nonprehensile Tails of the Platyrrhini (Primates) and Procyonidae (Carnivora)
TL;DR: The findings suggest that relatively greater ITC PCSAs can be functionally linked to the need for prehensile‐tailed taxa to suspend and support their body weight during arboreal behaviors, and maximizing ITC force production may not come at the expense of muscle excursion/contraction velocity.

Cranial ontogeny, diet, and ecogeographic variation in African lorises.
TL;DR: A basis for intrageneric taxonomic variation in Perodicticus is supported by such nonclinal size variation, as well as divergences in the ontogeny of masticatory proportions corresponding to interspecific variation in dietary proclivities.

Dynamic Modelling of Tooth Deformation Using Occlusal Kinematics and Finite Element Analysis.
TL;DR: Kinematics information recorded in a virtual environment derived from occlusal contact detection between high resolution models of an upper and lower human first molar pair is used to run a non-linear dynamic FE crash colliding test, demonstrating that knowledge about chewing kinematics in conjunction with a morphologically detailed FE model is crucial for understanding tooth form and function under physiological conditions.
Journal ArticleDOI
The relationships among jaw‐muscle fiber architecture, jaw morphology, and feeding behavior in extant apes and modern humans
TL;DR: Novel data is presented on masseter and temporalis internal muscle architecture for small- and large-bodied hominoids and models of fossil hominin and hominoid bite forces will be improved by incorporating architectural data in estimating jaw-muscle forces.

Modulation dynamics in the orofacial sensorimotor cortex during motor skill acquisition.
Fritzie I. Arce-McShane,Nicholas G. Hatsopoulos,Jye-Chang Lee,Callum F. Ross,Barry J. Sessle +4 more
TL;DR: The results suggest that the neuroplasticity in MIo and SIo occurring in parallel serves as a substrate for linking sensation and movement during sensorimotor learning, whereas the differing dynamic organizations reflect specific ways to control movement parameters as learning progresses.
