Lec 3 - Occlusal Surfaces, Contacts, Alignments Flashcards
curve from joining spee and wilson together
compensating curve
occlusal table is made up of the blank of the buccal and lingual cusps
inner inclines
cusp tips of supporting cusps are closer to the blank
central groove
supporting cusps are blank than guiding
duller
supporting cusps occlude with opposing blank
occlusal table
part of outer incline of supporting cusp that can occlude during maximal intercuspation
functional outer aspect
mesial distal cervical line form
toward cusp tip
labial lingual cervical line form
toward apex
cervical line form is more curved on this aspect of tooth
mesial
cervical line form of adjacent teeth have the same blank
cervical line form curvature (distal of one tooth and mesial of adjacent)
contact height on any given maxillary tooth is more incisal on the blank side
mesial
on posterior teeth, contact point is offset to blank so the blank embrasure is larger
buccal, lingual
axial positions refer to the tilt of the blank
root
tooth with most palatal inclination
3rd molar OR maxillary central
maxillary second premolar is the most blank tooth in the mouth
perpendicular
