Electromyographic recordings of anterior and posterior temporal and masseter muscles as well as anterior digastric muscles in 30 subjects with unilateral posterior crossbite and in a control group of 30 normocclusive subjects were made at rest position, during swallowing and during mastication.
For example, during stage 1 food transport, jaw and tongue muscles are very differently coordinated than during mastication, but still well coordinated, and show variation in relative phase.
In the present study, the two groups with non-submerged implants compared between them (groups 1 vs 2 and, groups 3 vs 4), the bone height was smaller, which is likely related to the presence of micromovements generated during mastication during the initial period of osseointegration [41].
A method was developed to characterize the textural attributes of semi-solid foods during "instrumental mastication".
Its fibrocartilaginous components form the articulating surfaces, with the biconcave TMJ disc allowing for smooth movement between the condyle and fossa during normal mastication.
This is associated with the chemical bonding between Si-69-modified nano ZnO and SBR chain during the mastication process.
Actually during the mastication process, chemical bond formation occurs between Si-69 and reactive sites of rubber as represented in Scheme 2 [20].
This is due to the formation of chemical bonding (C S linkage) between Si-69-modified nano ZnO and rubber during the mastication process as represented in Scheme 2.
Joint reaction forces have been shown to exhibit consistent patterns during the mastication cycle, and represent indicators of whether the joint region is being properly modeled [32].
Further, aldehydes may be formed during the mastication process by lipoxygenase activities.
Our preliminary observations showed that the disintegration mode varied greatly among different foods and was closely related to the initial food texture and its change during oral mastication and stomach digestion.
