Occlusion Flashcards
occlusion of opposing teeth when mandible is in the centric relation and MAY OR MAY NOT COINCIDE WITH THE MAXIMAL INTERCUSPAL POSITION AND IS INDEPENDENT OF TOOTH CONTACT
centric relation
side toward which mandible moves in a lateral excursion
working side
side of mandible that moves toward median line in lateral excursion
nonworking side
***buccal cusps are higher than lingual cusps and if the lines are drawn and connected it creates this
curve of wilson
**from distal cusp to mesial cusp starting from 2nd molar
curve of spee
teeth to look at in relation to each other for angle’s classfication of occlusion
maxillary / mandibular first molar
mesiobuccal maxillary groove against buccal groove of mandibular first molar in this class
angle’s class 1
two types of cusps
supporting/holding, guiding
supporting cusps of teeth
maxillary lingual, mandibular buccal
guiding cusps of teeth
mandibular lingual, maxillary buccal
complete intercuspation during occlusion that DOES NOT INVOLVED CONDYLAR POSITION
maximal intercuspal position
