Lec 4 Flashcards
after orthodontic treatment, tooth in neutral position indicates that
physiologic neutral as well so tooth doesnt move
memorize class diagrams
ok
only two teeth in the mouth that contact only one other tooth
max 3rd, mand central
memorize where each part of every tooth occludes with the other in class 1
ok
distance between incisal edges in maximal intercuspation vertically
vertical overlap
distance between incisal edges in maximal intercuspation due to projection of teeth beyond antagonist
horizontal overlap
influence of the contacting surfaces of anterior teeth on tooth limiting mandibular movements
anterior guidance
if horizontal overlap increases, anterior guidance blank
increases
distance between two points (middle of chin to nose) when occluding members are in contact
occlusal vertical dimension
distance between the two points when mandible is in physiologic rest position
rest vertical dimension
mandibular position assumed when head is upright and the elevators and depressors are in equilibrium in tonic contraction, condyles are neutral and unstrained
physiologic rest position
difference between the vertical dimension of rest and the vertical dimension while in occlusion
interocclusal rest space
IRS formula
VDR - VDO
side toward which the mandible moves in a lateral excursion
working side
side of mandible that moves toward midline during lateral excursion
nonworking side
