Q

Gingival exposure

A

How high the upper lip goes when smiling effects the amount of gingiva exposed

High smile line- gums show, medium smile line- ideal, and low smile line- lip hangs lower

17
Q

Anterior max contacts

A

Central:
Mesial-incisal Distal- incisal/middle junction

Lateral:
Mesial- incisal/middle junction. Distal- middle third

Canine:
Mesial- incisal/middle junction. Distal- middle third

18
Q

DH=FH

A

Max central incisal edge should be perpendicular to the facial midline

BUT it is more important that the max centrals are parallel to it

19
Q

Axial inclination

A

As you move distally, the crowns appear to have a more distal tilt in order to frame the smile

20
Q

Facial esthetics

A

Incisors should be parallel to the midline

21
Q

Ideal smile shape

A

Convex

The max incisal edges are below the canines, u shape
Natural appearance
