Flashcards in lingualized occlusion Deck (18):
1

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.

2

cusp locations in lingualized occlusion

lingual cusp of maxillary molars occlude in central fossa of mandibular teeth.

3

what tooth is dropped in a class 2 lingualized occlusion arrangement?

mandibular first PM

4

what tooth is dropped in class 3 lingualized occlusion?

maxillary first PM

5

mandibular cusps in lingualized occlusion

are shallow which allows the forces to be centered over the mandibular ridge

6

maxillary anatomic teeth have what degree of inclination?

33

7

mandibular teeth in lingualized occlusion

can be steep condylar guidance( shallow cusped), or shallow condylar guidance( non-anatomic teeth)

8

when settin the mandibular 2nd molar by what degree must it be elevated from the occlusal plane?

15

9

what should the space measure between the buccal cusps?

~1mm

10

whats the IIF rule?

if you have contacts on the inner inclines of functional cusps, they are in balance

11

what are functional cusps again?

cusps that occlude with the opposing central fossa.

12

whats important about the horizontal overlap in lingualized occlusion?

make sure it prevents biting of cheek and corner of mouth

13

all maxillary except which 2 should be on the plane of occlusion?

lateral incisor and cuspid

14

should the anterior teeth be in contact during excursions in lingualized occlusion?

yes they should be barely touching

15

what curvatures are used in lingualized occlusion to develop a balanced occlusion?

anteroposterior curvature and mediolateral curvature

16

whats the curve of monson?

its basically a sphere with its center at the glabella. the cusps and incisal edges of natural teeth touch a segment of the curve of monson

17

curve of spee

touch the tips of all mandibular teeth when the skull is viewed laterally.

18

factors that affect occlusal balance are

condylar balance, incisal guidance, angulation of occlusal plane, compensating curves, cusps on teeth or inclination of cuspless teeth,
