The Measurement of Maximal Bite Force in Human Beings
Background: Registering a true maximum bite force on the most commonly-used force transducers is problematic. It is often believed that this is related mainly to discomfort and the fear of breaking teeth. Objectives: The aim of the project was to compare the suitability of different bite force …

Seasonal Patterns of Plasma Testosterone Levels, Bite Force, and Locomotor Performance in Non-Territorial Male Lizards, Aspidoscelis Sexlineata
… of circulating testosterone, morphology, bite force, and locomotor performance in a non-territorial lizard species to address this hypothesis. Male Aspidoscelis sexlineata (n=133) were collected throughout the active season, and testosterone levels and performance capacities were measured. …

Determinants Of Bite Force In Four Species Of Sharks From The Gulf Of Mexico With An Emphasis On The Atlantic Sharpnose Shark, Rhizoprionodon Terraenovae
Bite force can provide valuable information regarding the physiological ecology of an organism. However, there have been few studies wherein bite force in sharks has been considered. Herein I report on a study of the bite force of four species of sharks with particular emphasis on that of the …

Effects of Testosterone and Training on Performance in the Non-Territorial Lizard (Aspidoscelis Sexlineata)
… mediator of seasonal increases in endurance and bite force, which are important for maintaining territories and winning male-male competitions. Aspidoscelis sexlineata, a non-territorial lizard, has elevated bite force and endurance during the breeding season when T levels are elevated (Gowan …

The relationship between masticatory stress and prognathism : a finite element and morphometric study
Mechanical forces, such as mastication, influence morphological characteristics of the cranium. With varying degrees of prognathism found within and between populations, the ability to accommodate masticatory stress may vary, and this will have profound effects on final craniofacial form. The …

Bat Skull Evolution: the Impact of Echolocation
… emission type) and functional measures (i.e., bite force, masticatory muscles and echolocation characteristics), using phylogenetic comparative methods. I found that skull diversification among bat families is mainly driven by sound emission type (i.e., nasal and oral) and broad diatary …

Mechanical Monitoring of Inhibitory Jaw Reflexes in Health and Simulated Dysfunction
… of this reflex in the form of changes in biting forces, and to investigate whether the mechanical manifestation of the inhibitory jaw reflex evoked by stimulation of the human upper lip, can be modulated by experimentally-controlled conditions that mimic symptoms of a myogenous temporomandibular …

A finite element study of the human cranium : the impact of morphological variation on biting performance
… found that muscle CSA, an estimator of muscle force, has low predictability. The fourth chapter assessed FE model sensitivity to variations in applied muscle forces. Results showed that a cranial FE model behaved reasonably robustly under variations in the muscle loading regimen.Chapter 5 uses …

Cranial form evolution and functional adaptations to diet among papionins : a comparative study combining quantitative genetics, geometric morphometrics, and finite element analysis
… deformations, and between diet and cranial form. Bite force and deformations show a less clear association with diet.

Diagnosing Bone Fracture to Assess Early Hominin Behaviour, Meat-Eating, and Socioecology at FLK-Zinjanthropus, Olduvai Gorge, Tanzania
… responses to loading extremes, b) impact-forces are significantly greater than the maximum carnivore bite-force, c) cones, incipient flakes, radiating cracks, and lateral stress features are characteristic of impact fracture, and e) Oldowan hominins at FLK-Zinj were responsible for …

Kinetics and Energetics of Feeding Behaviors in Daubentonia madagascariensis
… unmeasured behavioral modifications of bite forces using the post-cranial musculature. To do this I carried out two experiments measuring the kinetics of wood gnawing and the energetics of feeding behaviors. The main results of these experiments were: 1) Daubentonia does not generate …

Biomechanical Modeling of the Masticatory Region
… of the masticatory cycle, the joint forces during opening and closing of the jaw and distraction osteogenesis. In this thesis we present projects that aim to increase the understanding of the masticatory system as well as to increase the availability of computational jaw models. We …

The social environment and the evolution of morphology in the burying beetle, <em>Nicrophorus vespilloides</em>
… that beetles with larger heads exert a greater bite force. I then link this to the burying beetle’s natural history and show that head size predicts the outcome of contests over carrion, in both males and females. Finally, in Chapter 5, I investigate how head morphology functions in the …

Messung der dentalen und parodontalen Kräfte in zentrischer Okklusion
Die Erfassung der tatsächlichen Kräfte auf Zähne und Parodontium unter Bedingungen wie sie normalerweise im Mund auftreten ist bisher nicht schlüssig gelungen. Die Verwendung von dünnen Sensorfolien ermöglicht lediglich die Messung der auftretenden okklusalen Kräfte. In der vorliegenden Arbeit …

In-vivo-Bisskraft : Vergleich zwischen konventionellem und implantatgestütztem Zahnersatz
Die Aufgabe dieser Studie bestand darin, zunächst die individuell entwickelten unilateralen Bisskräfte an weiblichen und männlichen Probanden sowie an Patienten mit konventionellem und Implantat-gestütztem Zahnersatz zu messen. Zum Messvorgang wurde ein miniaturisierter piezokeramischer Sensor …
