Feeding Flashcards
feeding sequence components
ingestion - external to mouth, anterior teeth
stage 1 transport - posterior teeth, pull back, retraction of hyoid
mechanical processing - broken down, saliva, molars, squahsed on hard palate
stage 2 - bolus moved backwards
food processing muscles
mandibular muscles
suprahyoid
tongue muscles
lips and cheeks
tongue actions in chewing
control/transport bolus
gathers food, oclussal table, keeps of chewing surfaces, tongue/cheek in reciprocal manner, side to side and gathers for transport
forward movement and opening - squeze back mechanisms in tongue and hard palate
pharyngeal surface and wallowing
chewing cycle phases
opening - jaw depressor muscle active
occlusal - mandible stationary, teeth joined
closing - jaw elevator muscles active
balanced articulation
consider with prostheses
consider tongue movement
chewing performance
mehcanicl breakdown - facilitates swallowing, improve GI
poor masticatory perfomance
deteriorated can result in dietary restructuons
correlates with occlusal contact area
shortened dental arch
20 teeth, acceptable masticator function, aesthetics, maintenance of OH
occlusal stabiity, comfort, appearance
failure of shortened dental arch
occlusal isntability, occlusal collapse of bite, reduced biting ability, speech issues
maximum bite force
reduce in dentures, carried by mucosa of residual ridge = nto designed to bear masticatory loads
bite force increase by supporting dentures on teeth/implants
