11 final Flashcards
each functional cusp contacts the marginal ridges of opposing teeth or fossae of opposing teeth
cusp-marginal ridge
a one tooth to two teeth arrangement
cusp-marginal ridge
what does the majority of natural dentitions have as occlusion
-commonly used for single restorations
cusp-marginal ridge
each functional cusp occludes in a fossa of the opposing tooth
cusp-fossa
tooth to tooth arrangement
cusp-fossa
used when restoring both opposing quadrants of teeth
cusp-fossa
this occlusal relationship allows for some cusps to occlude onto marginal ridges and some others to occlude into fossae
cusp-marginal ridge
this only allows for each cusp to occlude into one fossa
cusp-fossa
anterior interocclusal contacts:
- mandibular central incisor contacts:
- mand lateral incisor contacts:
- mand canine contacts:
- mandibular central incisor contacts: max central incisor
- mand lateral incisor contacts: opposing central and lateral incisors
- mand canine contacts: opposing lateral incisors and max canine
(posterior interocclusal contacts)
