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.

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.

TL;DR: The authors found that the facial skeleton of the Australopithecus type species, A. africanus, is well suited to withstand premolar loads and that the mastication of either small objects or large volumes of food is unlikely to fully explain the evolution of facial form in this species.

Skeletal adaptations to mechanical usage: results from tibial loading studies in rats
TL;DR: It is hypothesize that strain rate determines the vigor of osteoblastic activity and the regularity of loading bouts determines osteoblast recruitment in a "quantum" fashion.

TL;DR: The achievements and advancements in dental technology brought about by computer-aided design and the all powerful finite element method (FEM) of analysis are reviewed.

In vivo bone strain patterns in the zygomatic arch of macaques and the significance of these patterns for functional interpretations of craniofacial form.
TL;DR: Data indicate that levels of functional strains during chewing and biting are highly variable from one region of the face to the next, and therefore it is unlikely that all facial bones are especially designed so as to minimize bone tissue and maximize strength for countering masticatory loads.

Symphyseal fusion and jaw-adductor muscle force: an EMG study.
TL;DR: Both the analysis of the W/B EMG ratios and the muscle firing pattern data support the hypothesis that symphyseal fusion and transversely-directed muscle force in anthropoids are functionally linked, which supports the hypotheses that the evolution of symphySEal fusion in anthropoid is an adaptation to strengthen the symphysis so as to counter increased wishboning stress during forceful unilateral mastication.
