16
Q

Describe Angle’s postulate

A

MB cusp of max 1st molar occludes in B groove of mand 1st molar

17
Q

The line of occlusion should follow a __________ curve

18
Q

Which line of occlusion?

Curve should pass through the central fossa of posterior teeth and lie along cingulum of anterior teeth

19
Q

Which line of occlusion?

Same line runs along buccal cusps and incisal edges of anterior teeth

20
Q

What type of malocclusion?

Normal relationship of 1st molars; line of occlusion incorrect due to malposed teeth, rotations, etc

A

Class I malocclusion

21
Q

What type of malocclusion?

Mandibular 1st molar is distal to maxillary 1st molar; maxillary canines are mesial to mandibular canines; line of occlusion not specified

A

Class II malocclusion

22
Q

What type of malocclusion?

Protruding maxillary incisors; associated with underdeveloped lower jaw, protrusive upper jaw, narrow arch, flared lower incisors

A

Class II Division 1 malocclusion

23
Q

What type of malocclusion?

Retruding or bunched maxillary incisors; associated with underdeveloped lower jaw, deep bite, laterals/canines in labioversion while centrals are upright with minimal overjet

A

Class II Divison 2 malocclusion

24
Q

What type of malocclusion?

Mandibular 1st molar is mesial to maxillary 1st molar by 1/2 cusp width or more; maxillary canines are distal to mandibular canines; line of occlusion not specified

A

Class III malocclusion

25
What type of malocclusion? Overdeveloped lower jaw; underdeveloped/constricted upper jaw; upright lower incisors; flared upper incisors
Class III malocclusion
26
Pros of Angle's classification (3)
Simple, widely accepted, has stood test of time
27
Cons of Angle's classification (5)
Focuses only on dentoalveolar relationships Does not recognize skeletal differences Ignores esthetics Does not include vertical/transverse dimensions Does not recognize tooth size differences
28
Angle's classification has been extended to include _________ patterns now
skeletal
29
What modern classification? Comprised of 5 main characteristics, which leads to development of a diagnosis: Intra-arch alignment Soft tissue profile Transverse plane of space Sagittal (A-P) plane of space Vertical plane of space
Ackermann and Proffit classification
30
Evaluation of the facial profile helps anticipate the __________ and __________ relationships
skeletal; occlusal
