lingualized occlusion Flashcards
advantages of lingualized occlusion
esthetics, better penetration of food bolus,decreased vertical and lateral forces, simpler technique, can be used in a wide vairety of patients, can be used with class 2 and 3.
cusp locations in lingualized occlusion
lingual cusp of maxillary molars occlude in central fossa of mandibular teeth.
what tooth is dropped in a class 2 lingualized occlusion arrangement?
mandibular first PM
what tooth is dropped in class 3 lingualized occlusion?
maxillary first PM
mandibular cusps in lingualized occlusion
are shallow which allows the forces to be centered over the mandibular ridge
maxillary anatomic teeth have what degree of inclination?
33
mandibular teeth in lingualized occlusion
can be steep condylar guidance( shallow cusped), or shallow condylar guidance( non-anatomic teeth)
when settin the mandibular 2nd molar by what degree must it be elevated from the occlusal plane?
15
what should the space measure between the buccal cusps?
~1mm
whats the IIF rule?
if you have contacts on the inner inclines of functional cusps, they are in balance
what are functional cusps again?
cusps that occlude with the opposing central fossa.
whats important about the horizontal overlap in lingualized occlusion?
make sure it prevents biting of cheek and corner of mouth
all maxillary except which 2 should be on the plane of occlusion?
lateral incisor and cuspid
should the anterior teeth be in contact during excursions in lingualized occlusion?
yes they should be barely touching
what curvatures are used in lingualized occlusion to develop a balanced occlusion?
anteroposterior curvature and mediolateral curvature
