Coordinated features in jaw and neck muscle activities induced by chewing of soft and hard gum in healthy subjects

Clinical and Experimental Dental Research, 2021
Backgrounds Jaw and neck muscles may be activated by chewing load using a hard food. However, it remains unclear how effects the gum hardness to the coordinated features in jaw and neck muscle activities during chewing performance.

Modeling and Simulation of Masticatory Muscles

Procedia Computer Science, 2015
AbstractMedical simulators play an important role in helping the development of prototype prostheses, pre-surgical planning and in a better understanding of the mechanical phenomena involved in muscular activity. This article focuses in modeling and simulating the activity of the jaw muscular system. The model involves the use of three-dimensional bone

EMG COMPARISON BETWEEN MASTICATORY MUSCLES WHEN USING NARROW DIAMETER IMPLANT ASSISTED MANDIBULAR OVERDENTUES [PDF]

Alexandria Dental Journal, 2019
INTRODUCTION: One of the primary objectives of complete dentures is to restore masticatory function in people who have lost their natural teeth. Patients wearing conventional complete denture (CD) often complain of instability of the mandibular denture ...

Muscle-Bone Crosstalk in the Masticatory System: From Biomechanical to Molecular Interactions

Frontiers in Endocrinology, 2021
The masticatory system is a complex and highly organized group of structures, including craniofacial bones (maxillae and mandible), muscles, teeth, joints, and neurovascular elements. While the musculoskeletal structures of the head and neck are known to

The Correlations Between the Mechanical Properties of Masticatory Muscles and Cranio-Cervical Posture

Reabilitacijos Mokslai: Slauga, Kineziterapija, Ergoterapija
Background and Aim. Upper crossed syndrome (UCS) is associated with prolonged static posture, muscular imbalance, and postural dysfunction. Altered activation of cervical and scapular stabilising muscles may increase tension in the masticatory muscles ...

Multiscale Coupling From Mastication to Retronasal Aroma Perception: The PG‐DTCFN Model and Multiphysics Simulation

Advanced Science, EarlyView.
Using grilled lamb skewers as a model system, this work builds a multiscale coupling framework from oral processing to retronasal aroma perception, reveals dual‐kinetic release patterns and Electroencephalogram‐characterized central encoding features, and proposes an interpretable physics‐guided deep learning model validated by multiphysics simulation,

Preservation of masseter muscle until the end stage in the SOD1G93A mouse model for ALS

Scientific Reports
Amyotrophic lateral sclerosis (ALS) progressively impairs motor neurons, leading to muscle weakness and loss of voluntary muscle control. This study compared the effects of SOD1 mutation on masticatory and limb muscles from disease onset to death in ALS ...

Lagomorph cranial biomechanics and the functional significance of the unique fenestrated rostrum of leporids

The Anatomical Record, EarlyView.
Abstract The crania of leporid lagomorphs are uniquely fenestrated, including the posterior cranial bones and the lateral portion of the maxilla. The functional significance of the highly fenestrated rostrum has received considerably little attention, despite being absent in other mammalian herbivores with a long rostrum.
