What are some examples of a class I neutroclusion?

Rostra (anterior) or caudal (posterior) cross-bite

Base narrow canines

19
Q

What type of malocclusion is a parrot mouth/ overshot?

A

Class 2 Mandibular distocclusion

— mandibular brachygnathism

20
Q

What class of malocclusion is an undershot jaw?

A

Class 3

— mandibular prognathism

21
Q

What type of malocclusion is a “wry” bite?

A

Class 4- asymmetrical skeletal malocclusion

22
Q

What is a lance tooth?

A

Rostral displaced adult canine tooth with a deciduous tooth in normal position

23
Q

Lance tooth is considered genetic in what breeds?

A

Sheltie

Schnauzer
Italian greyhound
Fox terrier

24
Q

What are possible treatments for lance tooth?

A

Non
Crown reduction + endodontic
Extraction
Orthodontics

25
Q

One or mor of the maxillary incisors are displaced toward the palate.
What is this?

A

Rostral (anterior) cross bite

Class I malocclusion

26
Q

One or more the the maxillary premolars are lingual to the mandibular premolars or molars

What do you call this?

A

Caudal (posterior) cross bite

Class I malocclusion

27
Q

What is “level bite”?

A

When the crowns of the incisors meet

Class III malocclusion —> prognathism

Leads to abnormal wear on incisors (attrition) commonly repaired by tertiary dentin

28
Q

What are causes of wry mouth?

A

Trauma

Inherited

29
Q

What are possible treatments for malocclusions?

A

Interceptive orthrodontics

Crown reductions

Orthodontic applicants
- eg “ball therapy” for base narrow canines

Exodontis

30
Q

What type of procedure is the removal of primary teeth to avoid or correct a problem?

A

Interceptive orthodontics

31
Q

What are possible causes of impacted teeth?

A

Lack of space in dental arch or mal-alignment of the tooth bud

Can result due to trauma, including traumatic extraction of retained primary teeth

32
Q

How are impacted teeth diagnosed?

A

Radiographs

33
Q

T/F: impacted or malformed teeth should be extracted in most cases?

A

True

  • can result in abscess or cyst formation
34
Q

T/F: a vial impacted tooth can potentially erupt into its normal position if the overlying gingiva and alveolar bone is removed

A

True

35
Q

What is a fluid filled cyst surrounding the crown of an unerupted tooth resulting form persistence of the enamel forming epithelium

A

Dentigerous cyst

36
Q
