AESTHETICS-Definition:It is the art and science of reality imitation which Refers to
natural harmony between teeth, supporting bones of jaw & soft tissues of face.
AESTHETIC CRITERIA
Alignment
Proportions
Shape & Form
Gingiva
Lips
Face
Color
aesthetic formula
A-Facial component
B-Periodontal component
C-Dental component
A-FACIAL COMPONENT
proportions• Facial composition is ideally divided into 3 equal parts with ideally sized & located.
• Symmetry and balance•Static (mirror image)•Dynamic (very similar but not identical)•Balance :tooth on either side are balanced out
MUSCULATURE (LIPS)• Lower lip design
There is a correlation between lower lip thickness & width of upper teeth length & inclination
• Upper lip design (smile line)
Determines the exposed area of anterior teeth. In addition it determines gingival exposure
Types:
• High
• Medium
• low
B-PERIODONTAL COMPONENT
Periodontal health should be optimally established :
• Before restorative treatment
• Maintained during the procedure
• In the final restoration
GINGIVAL TISSUE
Factors affecting gingival health:• Inflammation
• Systemic disease
• Iatrogenic factors
C-DENTAL COMPONENTIn order to achieve optimal dental esthetics a basic
knowledge of natural tooth anatomy is fundamental
• Shape and form• Semmetry• Position• Srface texture• Color• Translucency
• A smile is considered to be esthetically pleasing if each tooth in that smile (starting from the midline) is approximately 60% of the size of the tooth immediately mesial to it
?
Golden Rule
SHADE MATCHING
• It is the process of color replication of natural tooth
in a restoration
• 1- Shade is taken prior to tooth preparation.
• 2- Taken at the beginning of the visit and quickly .
• 3- Taken under different light sources .
• 4- Teeth should be clean and wet .
• 5- ꞌShade tabꞌ should be placed next to the tooth
to insure same background .
GENERAL GUIDELINES:
Munsell color systemHueQuality by which we distinguish one colorfamily from another .
ChromaQuality of color by which we distinguish astrong color from a weak one .
ValueQuality by which we distinguish a light color fron a dark color .
