13 final Flashcards
they influence the direction of the ridges and grooves on the occlusal surfaces and also the placement of the cusps
horizontal factors
means that the right condyle moves medially (same as left lateral movement)
right mediotrusion (mandible moves medially)
non-working pathways are also called
mediotrusive pathways
means that the right condyle moves laterally (same as right lateral movement)
right laterotrusion
working pathways are also called
laterotrusive pathways
the greater the distance of the tooth from the rotating condyle, the
wider the angle formed by the working and non-working pathways
same in mand and max
the greater the distance of the tooth from the midsagittal plane, the
wider the angle formed by the working and nonworking pathways
which teeth tend to have greater angles between mediotrusive and laterotrusive pathways
teeth that are more anterior in jaw like premolars
the angle formed by the working and non-working pathways increases as the amount of _____increases.
the directional of this also influences the angle
lateral translation increases
the angle formed by working and non-working pathways _____as the intercondylar distance increases
decreases
- distance from rotating condyle– greater the distance=
- distance from midsagittal plane– greater the distance=
- lateral translation movement–greater the movement=
- intercondylar distance-greater the distance=
- wider the angle (between laterotrusive and mediotrusive pathways)
- wider the angle
- wider the angle
- smaller the angle
another term for working interfering contact is
laterotrusive contacts (when mand in moving)
another term for non-working interference contacts is
mediotrusive contacts (when mand is moving)
initial stage of digestion
-rhythmic separation and closure of the teeth-control of the central pattern generator
-automatic/involuntary -can be controlled voluntary
mastication
single cycle of opening and closing.
tear shape
BEGINS AND ENDS AT MIP
chewing stroke
