Q

MANDIBULAR ROTATION: T/F- After rotation is complete, mandibular translation begins

A

22
Q

MANDIBULAR ROTATION: T/F- By reflex, the neuromuscular system is conditioned to include the maximum number of teeth in maximum intercuspation

A

true

23
Q

What plays the greatest role in DISOCCLUDING the POSTERIOR teeth in LATEROPROTRUSIVE movements?

A

anterior guidance

24
Q

This was an ODD one…Permanent mandibular molars usually possess roots that are collectively WIDER in a _____ direction than a _____ direction

A

wider in an MD direction than an FL??? Really?

25
Q

In protrusive movement, the permanent mandibular canines in a Class II occlusal relationship articulate with which of the following permanent maxillary teeth?

A

canines and lateral incisors…haha so a protrusive movement from a Class II is just saying MI…WTF.

26
Q

In a patient with a left canine protection, the ML surface of the perm MAX R 1st molar contacts the DF surface of the mand R 1st molar during a LEFT lateral excursion. This contact is ______ side interference.

A

non-working side interference

27
Q

A permanent maxillary canine can be distinguished from a mandibular first premolar because of the presence of a _______.

A

triangular ridge!

28
Q

The permanent mandibular lateral incisor, from incisal view, exhibits a crown ______ slightly on its root base

A

TWISTED

29
Q

In an ideal intercuspal relation, the tip of the mesiofacial cusp of the permanent maxillary second molar opposes

A

Facial groove of the mand 2nd molar…how did I get that wrong?!

30
Q

HAHAHA LOLZ-Which Angle’s classification represents a dental relationship in which the mand 1st molar is D to the max 1st molar and a normal square-shaped maxillary arch with retruded max central incisors, F malpositioned max lateral incisors, and an excessive vertical overlap?

A

Class II Division 2 (NICE GUESS!)

31
Q

NO FRIGGEN CLUE where he got this—-Which of the following permanent teeth would more frequently have a mesial concavity on its crown?

A

Mand 1st molar

32
Q

Which of the following permanent teeth are least likely to exhibit a root bifurcation??

A

MAXILLARY CANINES! (compared to mand canines, max 1st pm, duh…and max 2nd pm’s)

33
Q

T/F- ideal MI—-long axes of the maxillary and mandibular teeth aligned in a vertical direction

A

true

34
Q

T/F- ideal MI—- Angle Class I relationship involving the Permanent First Molars and Canines multiple and dominant contacts on anterior teeth

A

true

35
Q

T/F- ideal MI—- an adequate amount of tooth overlap

A

true

36
Q

T/F- ideal MI—-simultaneous contact of each posterior tooth

A

true

37
Q

Don’t get this wrong ever again: The lingual cusp(s) on which of the following permanent posterior teeth is (are) approximately 2/3 the height of the respective facial cusp(s)?

A

Mand 1st PM

38
Q

TRUE OR FALSE: In the frontal plane, the contour of the glenoid fossa’s medial wall of the nonworking side determines cusp height and central groove width, and the working side determines cusp height

A

True

39
Q

TRUE OR FALSE: Strong anterior teeth with healthy periodontal support, and a tight temporomandibular ligament on the working side cannot override mandibular lateral translation movements and variation in laterotruslve condylar movements

A

False

40
Q

TRUE OR FALSE: In the sagittal plane, the angle of eminence and the occlusal plane are changeable, non-tooth determinants of the occlusion

A

False

41
Q

TRUE OR FALSE: The functional horizontal overlap of anterior teeth is a changeable tooth determinant of occlusion

A

True

42
Q

TRUE OR FALSE: The vertical overlap of anterior teeth is a changeable tooth determinant of occlusion

A

True

43
Q

Primary maxillary molar teeth differ from permanent maxillary molar teeth in that the primary teeth have comparatively wider crowns in a ________ dimension.

A

faciolingual

44
Q

Please don’t get these wrong…On the occlusal surface of a maxillary molar, the groove that represents the working path of the distofacial cusp of the permanent mandibular molar is the _______ groove.

A

Facial

45
Q

T/F-In maximum intercuspation, the incisal edges of permanent mandibular anterior teeth occlude with the marginal ridges of the maxillary anterior teeth.

A

True!

46
Q

T/F? The occlusal contacts on the maxillary anterior teeth should be located approximately in the middle third of the crown.

A

True!

47
Q

I had no freggin clue (& rightfully so): The enamel usually extends farther apically on the lingual than on the facial surface on the permanent ______.

A

Mand Central Incisors

48
Q

True OR False??? The posterior aspect of the condyle has a GREATER articular surface area than the anterior portion of the condyle.

A

True

49
Q

True OR False??? The articular fossa must be contoured to receive the medial pole of the condyle, to allow for rotational movement to occur.

A

True

50
Q

When compared to the permanent maxillary canine, the permanent mandibular canine crown is normally ______ in a mesiodistal dimension.

A

narrower
