waxups 6 and 4 Flashcards
where are the proximal contacts for maxillary canines
mesial: incisal and middle third
distal: Middle third, more cervical
generally maxillary vs mandible: which are functional/non functional (lingual vs buccal cusps)
maxilla: lingual is functional, buccal is non functional
mandible: buccal cusps are functional, lingual are non functional
what is the functional and non functional canine cusp tips
maxillary are NOn functional, mandibular are FUNCTIONAL!! cusp tip and facial surface of mandibular canines is functional
where does the mandibular canine cusp tip/facial surface meet upper teeth
the lateral incisor and the maxillary canine , on their lingual surfaces toward incisal edge (regular occlusion) type i
what are left and right lateral movements of mandible
left of patient, from closed position or right of patient from closed position
during canine guidance, what does the canine come into contact with
only the opposing canine, no contact with posterior teeth.
when do you establish mesial/distal contact on a canine wax up
mesial with mesial cone
distal with distal proximal ridge
are the facial/lingual height of contours /labial and facial ridges concave or convex
facial is convex
lingual is both concave and convex (convex bottom concave top)
where are tooth 4 proximal contacts
at junction of middle and occlusal third
where is the buccal cusp cone on tooth 4
slightly mesial
which cusp ridge is shorter on tooth 4
mesial is shorter than distal
where is hte height of contour on tooth 4 buccal and lingual
BOTH buccal and lingual in cervical third
