Mandibular morphological variation : implications for fracture repair
Achieving a predictable clinical outcome during mandibular fracture repair necessitates thorough knowledge of variations of the neurovascular bundle, the location of tooth roots and bone quantity in
A morphometric analysis of prognathism and evaluation of the gnathic index in modern humans.
Changes in the mandibular angle during adulthood in South Africans
The purpose of this study was to measure the mandibular angle as a reflection of the biomechanical forces acting on the mandible and relate it to aging and loss of teeth.

A parallel test of the proposed Oyen, Walker, and Rice model on a cross-sectional sample of Australian Aboriginal juvenile crania showed no relation between tooth eruption and the supraorbital surface morphology thought to be indicative of active bone deposition.

The results suggest that in order to create an accurate and valid finite element model of the behavior of the primate skull at a particular instant during feeding, it is important to include estimates of the relative recruitment levels of the masticatory muscles.
A modified method for assigning material properties to FE models of bones.
Biomechanics of torsion in the human mandible.
Comparative investigations of mandibular function among primates have relied upon elementary structural models to estimate states of masticatory stress and strain, but these models are probably not consistently reliable for predicting the distribution of strains in the corpus.
Tendon-associated bone features of the masticatory system in Neandertals
The form and frequency of bone features known to be associated with internal tendons (structure) of the masticatory musculature in four species of macaques, three geographically distinct samples of modern humans, and Neandertals are examined to imply the presence of moderately stronger masticatories muscles in Ne andertals than in modern humans.
