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).

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

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.

Evaluation of masticatory performance and bite force in children with sleep bruxism

Journal of Oral Rehabilitation, 2012
Summary  The aim of this study was to evaluate the association between masticatory performance (MP) and bite force (BF) in children with sleep bruxism (SB) during the mixed dentition stage, considering also the occlusal characteristics. The sample was composed by 52 healthy children of both genders, aged 6–10 years.

Masticatory Force and Function in Patients with Hemispheric Brain Infarction and Hemiplegia

Journal of Dental Research, 1999
Recent functional animal studies have reported that the motor control of masticatory muscle function is bilaterally guided by both hemispheres, which may fundamentally differ from the cortical control of limb muscle function. In this study, we investigated whether unilateral cortical brain infarction induces different impairments in masticatory and ...

Effect of Jaw Opening on Masticatory Muscle EMG-Force Characteristics

Journal of Dental Research, 1993
This study was designed to evaluate the way in which changes in vertical jaw opening affected the relative contributions of various masticatory muscles to bite force production. EMG activity was recorded simultaneously from the masseter, and anterior, middle, and posterior temporalis muscles, during controlled isometric biting at different force ...

Relationship between myoelectric activity in masticatory muscles and bite force

European Journal of Oral Sciences, 1985
Abstract –Myoelectric activity in the anterior and posterior temporalis and in the masseter muscle was assessed in five subjects biting unilaterally on a bite fork at 50, 100 and 200 N for 60 s. The bite fork was placed between the right first premolars and the first molars. The ipsilateral muscle activity was recorded first, and the contralateral side

The validity of a method used for measuring masticatory forces

The Journal of Prosthetic Dentistry, 1960
Abstract An investigation into the validity of a proposed method for measuring the masticatory forces transmitted through a denture base has been presented. Laboratory equipment was built to represent a denture in the mouth. Known loads were applied, and measurement of the load was attempted.
