What factors are assessed in esthetic analysis?
- facial symmetry
- smile symmetry
- occlusion
- tooth size, shape, and color
What are factors are considered when determining facial symmetry?
- inter pupillary line
- midline axis
- commissural line
- occlusal plane
What factors are assessed with smile symmetry?
- smile line
- buccal coridor
- lip line/tooth reveal
- gingival height/position
What factors are assessed with occlusion?
- guidance
- parafunctional habits
- location of occlusal contacts
- facial symmetry
- smile symmetry
- occlusion
- tooth size, shape, & color
factors assessed in esthetic analysis
Describe some factors that are evaluated when determining facial symmetry:
- inter pupillary line
- midline axis- cupid’s bowl ad philtrum
- commissural line
- occlusal plane line
Describe what contributes to ideal facial symmetry:
inter-pupillary, commissural, and occlusal plane lines are parallel
Refers to the vertical contact interface between two maxillary centrals:
dental midline
Ideally, the dental midline should be coincident with:
facial midline axis
The dental midline is not noticeable by most people up to ____ as long as its ____
4mm; parallel to MA
T/F: Dental midlines DO NOT coincide in about 75% of cases
True
A ____ dental midline is more esthetically unpleasant and more noticeable than a ____ midline
canted; shifted
Refers to the relation of the incisal edge line to the lower lip:
smile line
List some categories of smile lines:
- convex
- straight
- reverse
Smile line influences the final configuration of:
- Incisal edge position
- crown form
- length of the maxillary anterior teeth
When referring to an acceptable smile line, the maxillary incisal edges are _____ to the line of the lower lip
parallel
When referring to an acceptable smile line, the lateral incisor are ___ to ____ above the lower lip line
0.5 mm - 1.5mm
When referring to an acceptable smile line, the centrals and cuspids will approximate the lower lip near or at:
the vermillion border (wet dry junction)
The amount of vertical tooth exposure in smiling- in other words the height of the upper lip, relative to the maxillary central incisors:
lip line
Lip line is defined as the amount of _____ tooth exposure in smiling
VERTICAL
The lip line can be described as:
- normal
- low
- high
Categorize the following lip line:
greater than or equal to 75% of central incisors with 2 mm of gingival display
Normal
Categorize the following lip line:
less than 75% of central incisor display during smiling:
Low
Categorize the following lip line:
greater than or equal to 3 mm of gingival display during smiling
High
