17
Q

What describes a malocclusion in which a mandibular tooth or teeth have a more buccal or labial position than the antagonist maxillary tooth?

A

Crossbite (XB)

18
Q

What term describes when one or more of the mandibular incisor teeth is labial to the opposing maxillary incisor teeth when the mouth is closed?

A

Rostral crossbite (CB/R)

19
Q

Is a rostral crossbite considered to be a normal occlusion?

A

Yes, except that one or more of the incisors are malaligned

20
Q

What is the treatment for rostral crossbite?

A

Extraction

Placement of an orthodontic appliance to move the maxillary teeth labially and the mandibular teeth lingually

21
Q

What is rostral crossbite similar to in human terminology?

A

Anterior crossbite

22
Q

What describes when one or more of the mandibular cheek teeth are buccal to the opposing maxillary cheek teeth when the mouth is closed?

A

Caudal crossbite (CB/C)

23
Q

How are the maxillary and mandibular premolars aligned in a caudal crossbite?

A

The maxillary premolars are lingual to the mandibular premolars or molars

24
Q

What term is caudal crossbite similar to in human terminology?

A

Posterior crossbite

25
Q

What occurs in a class 2 occlusion (MAL2)

A

The mandible is shorter than normal

26
Q

What does a class 2 occlusion cause?

A

The adult canines and incisors to penetrate the hard palate

Irritation and ulceration of the hard palate may result

27
Q

What is mandibular prognathism?

A

When the mandible is too long

28
Q

What does mandibular prognathism cause?

A

The mandibular incisors occlude labial to the maxillary incisors, which may cause excessive wear and injury to both teeth

29
Q

What is “excess freeway space”

A

When the mandible is bowed causing excess space between the premolars

30
Q

What is Maxillary brachygnathism?

A

A shortened maxilla

31
Q

What occurs with maxillary brachygnathism?

A

The maxillary teeth are rotated as a result of crowding

32
Q

What does maxillary brachygnathism cause in the mandible?

A

The mandible may be bowed, causing excess space between the upper and lower premolars

33
Q

What was Asymmetric Skeletal Malocclusion once called?

A

Wry bite

It was nonspecific so it is no longer used

34
Q

What does class 4 malocclusion (MAL4) cause?

A

The central incisors of the mandible and maxilla do not align evenly

35
Q

What may class 4 malocclusion be caused by?

A

An uneven mandibular lengths or by the failure of the maxilla to develop evenly

36
Q

How does Class 4 malocclusion occur?

A

May be genetic

May be caused by trauma to the bones durine development of the facial structure

37
Q

How is class 4 malocclusion treated?

A

Extraction of teeth

Placement of orthodontic appliance

38
Q

A type of asymmetric skeletal malocclusion is maxillary-mandibular asymmetry. This can occur in two different directions. What are they?

A

Rostrocaudal
Side-to-side
Dorsoventral

39
Q

Which maxillary-mandibular asymmetry occurs when the mandibular mesioclusion or distoclusion is present on one side of the face while the contralateral side retains normal dental alignment?

A

Rostrocaudal (MAL4/RC)

40
Q

Which maxillary-mandibular asymmetry occurs when there is a loss of the midline alignment of the maxilla and mandible?

A

Side-to-side direction (MAL4STS)

41
Q

Which maxillary-mandibular asymmetry results in an open bite that is defined as an abnormal vertical space between opposing dental arches when the mouth is closed?

A

Dorsoventral (MAL4/DV)
