The development of the chin, a feature unique to humans, suggests a close functional linkage between jaw biomechanics and symphyseal architecture. The present study tests the hypothesis that the presence of a chin changes strain patterns in the loaded mandible. Using an anatomically correct 3-D model of a dentate mandible derived from a CT scan image, we analyzed strain patterns during incisal and molar biting. We then constructed a second mandible, without a chin, by ‘defeaturing’ the first…

Effect of mandibular advancement on symphyseal form

This study provides no evidence to suggest that increasing mandibular length results in changes in wishboning resistance in adult humans, and indicates that the symphysis was not responding to increased wishBoning, which would predict an increase in absolute cortical thickness and no change in relative wishboned resistance.

Why do humans have chins? Testing the mechanical significance of modern human symphyseal morphology with finite element analysis.

The results of this study corroborate prior hypotheses about the mechanical effects of the human chin and vertical symphysis orientation and support the idea that the relative importance of wishboning and vertical bending in the coronal plane might have played a role in the evolution of modern human symphyseal morphology.

Symphyseal surface strain during in vitro human mandibular wishboning.

Human symphyseal form, with its distinctive chin, is unlikely to be adapted for countering wishboning loads, which runs counter to the optimality criterion typically invoked in assessing trait performance for signs of adaptation.

When anthropological considerations influence our attitude about the chin and orthognathic surgery

Recent research based on the analysis of stress using the finite element method (FEM) seems to establish that the presence of the chin is a biomechanical consequence of skeletal and muscular equilibrium peculiar to the human face.

The ontogeny of the chin: an analysis of allometric and biomechanical scaling

It is indicated that ontogenetic increases in chin projection do not provide greater bending resistance to the mandibular symphysis, and a complex interaction between symphyseal ontogeny and bending resistance is suggested.

Numerical and Experimental Models of the Mandible

This study proved that FE models of the mandible can reproduce experimental strains within an overall agreement of 10% and can be used for the design of a novel TMJ implant considering other load configurations and bone mechanical properties.

The correlation of chin prominence and esthetics

Perceived attractiveness of the profile is sensitive to millimeter changes in chin prominence, and there is only weak correlation between chin soft tissue thickness and skeletal measurements.

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.

Comparative Functional Morphology of Maximum Mandibular Opening (Gape) in Primates

There is wide variation among primates in the size and shape of teeth, the size and position of masticatory muscles, and the morphology of the craniofacial skeleton. The functional significance of

Three-dimensional finite element stress analysis of the dentate human mandible.

The results suggested that although the mandible behaved in a beam-like manner, its corpus acted more like a combination of open and closed cross sections due to the presence of tooth sockets, at least for the task modelled.

Biomechanical scaling of the hominoid mandibular symphysis

Experimental investigation of mandibular bone strain in cercopithecine primates has established that the mandible is bent in the transverse plane during the power stroke of mastication. Additional

It is concluded that the applied procedure of generating the FE model is a valid and accurate, non-invasive method to predict different parameters of the complex biomechanical behaviour of human mandibles.

The data suggest that during the power stroke of mastication, the macaque symphysis is predominately sheared dorsoventrally and/or twisted about a transverse axis and bent by lateral transverse bending of the mandibular corpora.

Cross-sectional geometry and morphology of the mandibular symphysis in Middle and Late Pleistocene Homo.

The decoupling of bending resistance and mentum osseum form in the Late Pleistocene suggests that the evolutionary emergence of the modern human "chin" was at least partly independent of the biomechanical demands placed on the symphysis.
