This document discusses mini-esthetics and micro-esthetics in dentistry. Mini-esthetics includes assessing the relationship between teeth and face, including tooth display, symmetry, and vertical relationships. Micro-esthetics examines individual tooth characteristics like size, shape, proportions and shade. Key factors discussed are smile line, buccal corridors, gingival heights and contours, connectors, embrasures, and black triangles. Tooth shade should get darker from central to lateral to canine. Together mini and micro-esthetics provide guidelines for analyzing esthetic details of the teeth, face, and smile.

ESTHETICS

2. MINI ESTHETICS
Includes assessment of the relationship of dentition to the face (tooth-lip
relationship and smile analysis)
• Incisor display
• Gingival display
• Smile analysis

3. SYMMETRY - relationship of dental midline of each arch to the skeletal midline of the
jaw

4. VERTICAL RELATIONSHIP:
 INCISAL STOMIAN:
• amount of maxillary central incisors exposure beneath the upper lip when the patients lips are at
rest.
• Incisal display at rest: 1-4 mm (ideal)
• Incisal display on smile:
100% incisal show is ideal
75% crown display (minimum for excellent esthetics)
Females- 1-2 mm of gingival display is ideal
Males- only incisal show
• Measured from the lower vermillion border of the upper to the incisal edge on rest and on
smiling.

5. SMILE ASSESSMENT
• Smile line
• Smile arc
• Buccal corridors
Smile line:
• vertical display
• Low, average or high

6. Smile arc:
• Relationship of maxillary incisal edges with the curvature of lower lip in a posed smile.
Consonant: In an ideal smile, the incisal edges of the maxillary anteriors are parallel to the
curvature of the lower lip.
Non- consonant: flat incisal curvature.

7. BUCCAL CORRIDORS
• Transverse dimensions of the smile
• Space between the buccal surface of posterior teeth (maxillary premolars) and the angle of
mouth on smiling
WIDE:
-Too much space
-Negative spaces
-Can be due to constricted arch
NARROW:
-Less space

8. MICRO-ESTHETICS
The esthetics of individual tooth including the size, shape and
shade
The teeth in relation to each other

9. TOOTH PROPORTIONS
• In relation to height and width of anterior teeth
• For 10mm height of the crown there should be 8mm width

10. MESIO-DISTAL WIDTH (GOLDEN
PROPORTION)
• Width of the maxillary anterior teeth on smile and their actual mesiodistal width
differ because of curvature of dental arch.
Apparent width of lateral incisor should be 62% of the width of central incisor
Apparent width of canine should be 62% of the width of lateral incisors
Apparent width of the 1st premolar should be 62% of the width of the canine
• This guideline helps us to determine the post-treatment size of lateral incisors in
case they’re disproportionately small of large or when canines are narrowed to
replace missing laterals

11. GINGIVAL HEIGHTS, SHAPE AND
CONTOUR
HEIGHT:
• Proportional gingival heights are needed to produce a normal and attractive dental appearance
• Establishing a correct gingival level for each tooth will help create a pleasing smile
• Generally;
I. Central incisor – highest gingival level
II. Lateral incisor – 1.5mm lower
III. Canine – at the level of central
• Important during tooth substitutions
• Differences of more than 2 mm are noticeable

12. SHAPE:
• Curvature of gingiva at the margin of the tooth
• Gingival shapes of;
I. Maxillary centrals - elliptical
II. Maxillary laterals – symmetric half-oval or half-circle
III. Maxillary canines – elliptical

13. CONNECTORS AND EMBRASSURES
CONNECTORS:
• Interdental contact area
• Areas where adjacent teeth appear to touch and may extend apically or occlusally from the actual
contact point
• The actual contact point is a small area
• The connector includes the contact points as well as areas above and below
• Normal connector height – greatest between the central incisors
EMBRASSURES:
• Triangular spaces, incisal and gingival to the contact points
• Ideally, larger in size than the connectors
• Gingival embrasures – filled with interdental papillae

14. BLACK TRIANGLES
• Occur as a result of short interdental papillae
• Leaves an open gingival embrasure above the connectors
• Actual and potential black triangles to be notes during
examination

15. TOOTH SHADE AND COLOUR
• Younger age – whiter and brighter
• Older age – darker and duller
• Brighest tooth in mouth is central  lateral  canine
• Shade of premolar matches to that of lateral incisors
