The Effect Of The Magnıtude And Dırectıon Of The Mastıcatory Muscle Forces And Bıte Force On The Temporomandıbular Joınt Reactıon Force

Turkish Journal of Orthodontics, 1998
The abnormal loads on the temporomandibular joint (TMJ) may lead to degenerative diseases. Orthodontic and orthognathic surgery treatments change the effects of muscle and bite force moment arm on the TMJ.

Stress distribution in the cervical region of an upper central incisor in a 3D finite element model

Brazilian Oral Research, 2009
The aim of this study was to evaluate the stress distribution in the cervical region of a sound upper central incisor in two clinical situations, standard and maximum masticatory forces, by means of a 3D model with the highest possible level of fidelity ...

Measurements of masticatory forces in the horse

Pferdeheilkunde Equine Medicine, 2006
There is a need for specific data on equine mastication in several fields: (1) In nutritional science, the disruption of the forage is crucial to sufficient energy uptake in the horse (Frape 1990). (2) In mandibular/oral surgery, knowledge about the motions of the jaws and about chewing forces is necessary for the development of techniques and ...

Finite element analysis of feeding in red and gray squirrels (Sciurus vulgaris and Sciurus carolinensis)

The Anatomical Record, EarlyView.
Abstract Invasive gray squirrels (Sciurus carolinensis) have replaced the native red squirrel (Sciurus vulgaris) across much of Great Britain over the last century. Several factors have been proposed to underlie this replacement, but here we investigated the potential for dietary competition in which gray squirrels have better feeding performance than ...

Masticatory performance and bite force in children with primary dentition [PDF]

Brazilian Oral Research, 2007
The aim of this study was to evaluate the relationship between masticatory performance and maximum bite force in the primary dentition. The sample comprised 15 children of both genders, aged 3 to 5.5 years, with good systemic and oral health, presence of all primary teeth without large caries, no structural anomalies, without severe malocclusion, and ...

Tooth eruption status and bite force determine dental microwear texture gradients in albino rats (Rattus norvegicus forma domestica)

The Anatomical Record, EarlyView.
Abstract Dental microwear texture analysis (DMTA) is widely applied for inferring diet in vertebrates. Besides diet and ingesta properties, factors like wear stage and bite force may affect microwear formation, potentially leading to tooth position‐specific microwear patterns.

Quantitative assessment of masticatory muscles based on skull muscle attachment areas in Carnivora

The Anatomical Record, EarlyView.
Abstract Masticatory muscles are composed of the temporalis, masseter, and pterygoid muscles in mammals. Each muscle has a different origin on the skull and insertion on the mandible; thus, all masticatory muscles contract in different directions. Collecting in vivo data and directly measuring the masticatory muscles anatomically in various Carnivora ...
