Estimated masticatory forces in patients before orthognathic surgery

Journal of Oral and Maxillofacial Surgery, 1994
There has been relatively little study of masticatory forces in dentofacial deformity patients before orthognathic surgery. This study used a mathematical equation based on electromyographic activity (EMG) during mastication and forces obtained during isometric bites to estimate masticatory forces in 55 control subjects and 48 patients. Subjects chewed

Bite force in patients with functional disturbances of the masticatory system

Journal of Oral Rehabilitation, 1975
SummaryIn thirty patients (24 women and 6 men) treated because of dysfunction of the masticatory system at the department of Stomatognathic Physiology, University of Gothenburg, bite force was registered before, during and after treatment had been completed.

Human Masticatory Muscle Forces during Static Biting

Journal of Dental Research, 2003
Muscle forces determine joint loads, but the objectives governing the mix of muscle forces involved are unknown. This study tested the hypothesis that masticatory muscle forces exerted during static biting are consistent with objectives of minimization of joint loads (MJL) or muscle effort (MME).

Occlusal function and electromyographic activity of masticatory muscles in skeletal Class III patients with different patterns of mandibular asymmetry.

Journal of Oral Rehabilitation, 2023
BACKGROUND Although jaw asymmetry is commonly seen in skeletal Class III patients, its correlation with occlusal function and masticatory muscle activity has not been fully elucidated.

Biomechanical evaluation of the equine masticatory action: Calculation of the masticatory forces occurring on the cheek tooth battery

Journal of Biomechanics, 2009
The forces generated during equine mastication influence the teeth, as well as the periodontium, the jaw bones, the temporomandibular joints and materials used in dental therapy. Due to the limited accessibility of the cheek teeth located farther caudal in the equine oral cavity the measurement of the masticatory forces on these teeth is virtually ...

Symmetric force response of human masticatory muscles to stretch and unloading

Experimental Brain Research, 1997
During chewing, the force exerted by the jaw-closing muscles must constantly adapt to changing resistances between the teeth, as the food is broken down. In the present study, the changes in biting force resulting from small, controlled displacements imposed on isometrically contracting jaw-closing muscles were measured. We found that the force changes

Comparison of biting force and masticatory efficiency in patient with different denture base material

Al-Azhar Journal of Dental Science, 2018
Background: The potential alternative materials to PMMA are the polycarbonates and the nylon denture base resins. Of this nylon is the generic name for certain types of thermoplastic polymers belonging to the class polyamides.

Migraine and Masticatory Muscle Volume, Bite Force, and Craniofacial Morphology

Headache: The Journal of Head and Face Pain, 2001
The purpose of this investigation was to compare the masticatory muscle volume, bite force, and craniofacial morphology of migrainous subjects with age‐ and sex‐matched controls. Ten adult dentate migraineurs were matched with 10 dentate age‐ and sex‐matched controls.

Endurance tests of the masticatory system on different bite force levels

European Journal of Oral Sciences, 1988
Abstract — Endurance tests of the masticatory system were performed in three different groups of healthy volunteers in order to investigate the relation between bite force and endurance time on different force levels. The subjects clenched a bite fork until exhaustion.
