Masticatory

Rosin ester resins are used as modifiers in the formulation of chewing gum. The rosin derivative modifies the physical properties of the polymer used, providing the desired masticatory properties. The glycerol ester of hydrogenated rosin is the predominant choice, because stabilized materials have improved aging resistance, which extends the shelf life of the gum. 

Resilient Diners. Resilient liners reduce the impact of the hard denture bases on soft oral tissues. They are designed to absorb some of the energy produced by masticatory forces that would otherwise be transmitted through the denture to the soft basal tissue. The liners should adhere to but not impair the denture base. Other critical properties include total recovery from deformation, retention of mechanical properties, good wettability, minimal absorption of...

In severe cases, or those refractory to treatment, truncal and limb weakness may be accompanied by involvement of masticatory, bulbar, and respiratory muscles. However the most life-threatening clinical manifestations are those affecting the gastrointestinal tract, since stomach ulceration can occur and death from perforation and peritonitis are not unknown. Medication with steroidal antiinflammatory agents is necessary but weakens the childrens resistance to infection, so that systemic spread of usually self-limiting disorders, such as candidiasis, may occasionally occur.

Patients who have received neuroleptics for long periods of time may develop a hyperkinetic disorder of the extrapyramidal system characterized by involuntary, purposeless movements affecting many parts of the body. This is known as tardive dyskinesia. Most commonly, these are manifested in a syndrome involving abnormal movements of the tongue, mouth and masticatory muscles. There are also choreoathetoid movements of the extremities. The mechanism by which these symptoms develop remains unknown.

Masticatory substances are of (11 vegetable origin, or (2) the products I organic synthesis. In the ease of anhydrous lanolin, the suurce is fat from the wool of sheep. 

During the last several decades, naturally derived masticatory substances have been displaced to a considerable degree by synthetic materials — for reasons of availability, economics, and. frequently, better control over purity. These developments essentially paralleled the development of Ihe synthetic rubbers for industrial uses. Some of the synthetic substances now used and listed in the "Food Chemicals Codex, published by the National Academy of Sciences (Washington. DC) include- butadiene-styrene 75/25 rubber butadiene-styrene 50/50 rubber glycerol ester of partially dimerized rosin glycerol ester of partially hydrogenated wood... 

The plunger is the mastication device and two motors regulating the vertical and circular movements control its masticatory movements.

The watery component of saliva moistens and lubricates the masticatory process. Salivary mucus helps to bind the food bolus ready for swallowing. The surface coating of mucus also serves to protect the epithelium from potentially harmful substances. Enzymes present in the saliva initiate the digestive process.
