Course Review- L2 Flashcards
What factors are assessed in esthetic analysis?
- Facial symmetry
- Smile symmetry
- Occlusion
- Tooth size, shape and colo
What factors are considered when determining facial symmetry:
- interpupillary line
- midline access
- commissural line
- occlusal plane
What factors are assessed when determining smile symmetry:
- smile line
- buccal corridor
- 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 and tooth size/shape/color:
Factors assessed in esthetic analysis
Describe some factors that are evaluated when determining facial symmetry:
- interpupillary line
- midline axis- cupids bow and philtrum
- commisural line
- occlusal plane line
Describe what contributes to ideal facial symmetry:
Inter-pupillary, commisural 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 ____
4 mm; parallel to midline axis
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 configuraiton 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 incisors are ____ to ____ above the lower lip line
0.5 mm to 1.5 mm
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
- heigh
Categorize the following lip line:
> /= 75% if central incisors - 2mm of gingival display
normal
Categorize the following lip line:
<75% of central incisor display during smiling
low
Categorize the following lip line:
> /= to 3mm of gingival display during smiling
high
