Basic Principles of Esthetics and Anterior Tooth Contours Flashcards
What is Esthetics
Beauty basically
What did DeVan say the goal of Prosthodontic treat is
To preserve what remains (i..e. Support remaining teeth and prove a substitute for missing teeth)
Elements of Prosthetic Rehab
Occlusion
Esthetics
Phonetics
Macro Esthetics
Facial Composition
Mini Esthetics
Dentofacial Composition
Micro Esthetics
Dental Composition
What does Esthetics comtain
Dental, dentofacial, and Facial composition
Why would teeth be white and chalky
Not enough Ca
why are teeth clear/yellowish
Because they are clear and you can see the dentin
Who focuses and the Dental Composition
The dentist
Who focuses on the Dentofacial composition
The Specialist
Who focuses on the Facial Composition
The surgeon
What is all part of Esthetic Harmoney
Frame and Reference
Proportion and Idealism
Symmetry
Perspective and Illusion
What is used as the frame and Reference for Dental esthetics
Veritcle Reference Lines
- Bridge of the nose
- Philtrum
- Face midline
- Dental Midline
The 1/3 thing for Proption and Idealism
The face is 1/3 between eyebrowns and Hair line
1/3 between eyebrows and Philtrum
1/3 between philtrum and chin
Must all proportions be the same
No, can break rules, but must at least understand way
Pythagorus Golden Proportion
1.618:1
Plato’s Golden Proportion
1.733:1
where is the golden proportion found in the face
In the teeth due to the curve of the teeth
The REgularity in the Arrangement of teeth
Symmetry
Why must symmetry be introduced in the dentofacial composition
to create a positive psychological response
Must things be perfectly symmetical to be esthetic
No, should have a small amount of asymmetry
What all is important for Symmetry
Dental Midline
MAxillary Central incisors
Maxillary lateral incisors
Maxillary canines
What is all included in perspective and Illusion
Widening and narrowing
Shortening and lengthening
Contrast
Shading
Types of Lip lines
High- shows lots of gingiva
Moderate- shows a tiny bit of singiva
Low- shows no gingiva
The smile line
A hypothetical curved line drawn along the edges of maxillary anterior teeth that has the coincide or run parallel to the curvature of the lower lip
who has a more pronounced smile line
Women
Components of a smile
Lip line Smile line Upper lip curvature Buccal Corodor Axial Alighnment and Gradation Dominance Embrasures Dental Morphology Gingival Morphology
What causes the upper lip to curve
Due to muscles
The dark triangles on the side of the teeth
Buccal corridor
What is considered esthetic in the Buccal Corridor
Large Buccal Corridors
What is it called to have a small buccal corridor
Mouth full of teeth
how does the axial surfaces of the teeth alighn
All teeth should be in line with similar angulation
The dominant teeth in the smile
2 central incisors
How should the Cnetral incisors look for good estehtics in dominance
White and flat
Forms of Esthetic Embrasures
Form
Symmetry
Progression
What should the Embrasure size be
larger as more distal
Parts of dnetal morphology
Contact area and embrasures- teeth should connect
Texture- should have bumpish texture on the surface but really isnt obvious
How to get the correct texture on teeth
Use Carbide Finishing bur and then glaze
Parts of Gingival Morphology
Gingival tissue and racial factor
Gingival health and contour
Gingival Zenith
What are some gingival defects
Gingival cleft: a divet High frenum m insertion Blunted papilla- doesn't go all the way between deeth Gingival asymmetry Ridge defect Gingival recession
