when the maxillary and mandibular teeth come together in a fully closed position
if occlusion is off, it can affect what three thing?
T/F occlusal disharmony can cause recession or cracks in the teeth.
true giggity giggity!
occlusal trauma of the teeth and periodontium can cause:
irreversible occlusal trauma can lead to:
for checking normal occlusion, look at the ____ _______ and if they are missing, use the ________.
normal occlusion=________ occlusion
the MB cusp of the maxillary first permanent molar occludes with the buccal groove of the mandibular first permanent molar. which classification is this?
normal (ideal) occlusion
T/F it is normal for normal occlusion to occur naturally.
false! it is rare
when would you want someone in centric occlusion (normal bite)?
to determine classification
the way you bite normally is called _________ occlusion
habitual ("i bet you'll" occlude like that everyday!)
Habitual occlusion ___________ forces of impact
does tooth loss rearrange the occlusion? what else does it do?
it most certainly does!
cause a little of that what i like to call "drifting" to occur
centric occlusion is also called _________ occlusion
how do you measure the overjet?
with a probe from the facial mandibular to the lingual of the maxillary incisor
the natural HORIZONTAL overhang of the maxillary arch over the mandibular arch:
overjet the what jet? the jet that flew over the horizon!
T/F an overjet is equally distributed in males and females
T - R - U - E what does it spell?? TRUE!
normal amount of VERTICAL overlap allows for contact between the posterior teeth during mastication
when that maxillary teeth come within the INCISAL third of the mandibular teeth:
T/F overbite is more common in females
why does overbite and overjet tend to diminish with age?
because of mandibular growth and later, attrition
incisal edges of the maxillary teeth are within the MIDDLE third of the facial surfaces of the mandibular teeth
incisal edges of the maxillary teeth are within the CERVICAL third of the facial of the mandibular teeth:
incisal edges of the mandibular teeth are in contact with the maxillary lingual gingival tissue, the overbite is considered:
what are the two types of contact areas:
teeth that meet mesially and distally. stabilize the teeth:
food impaction and gum troubles is caused from:
all the spots where the contact points hit:
what are the 3 areas of interdigitation during centric occlusion?
height of cusp contour
tip of the cusp:
height of contour
marginal ridges are ________
other cusp that occludes into the fossa
cusps that function during centric occlusion:
tooth to tooth wear:
smooth surface that is flat on the incisal,occ, or buccal
articulating paper is used to check ______ _______ after a restoration is placed:
if a restoration is too high, what are two things it can cause?
the end point of closure of the mandible
is centric relation a natural position?
for centric relation, the clinicial will ease the mandible into _______ position
where one or two teeth hit too soon
too much sliding
moving the mandible right and left until the canines on the side you are looking at are in a cusp to cusp relation
lateral occlusion (excursion)
during lateral occlusion, the side where the mandible has moved is called the ________ _______
the side of the arch opposite to the working side during lateral occlusion is called the:
in normal occlusion, the canine should be the only tooth functioning during the lateral occlusion, this is called:
if all the opposite arch posterior teeth are sharing the occlusion (if there is no canine rise) during lateral occlusion, it is called:
if teeth make contact on the opposite side during lateral occlusion, it is called:
when all eight of the centrals and laterals are end to end during anterior protrusion:
if some teeth don't touch during protrusive occlusion:
when the mandible is at rest, it is in a ________ state
when you fall asleep, your teeth should have ______ ______, the space between in relaxed rest
lack of overall ideal form in the dentition while in centric occlusion:
T/F malocclusion can be hereditary
____% of kids/teenagers show some degree of malocclusion
shadows where they are not supposed to be:
negative space (not supposed to be in a dark alley way)
