Final; Basic Principles of Esthetics and Anterior Tooth Contacts Flashcards
DeVan in 1952 determined what
the goal of prosthodontic treatment is to preserve what remains; support remaining teeth and provide a substitute for missing ones
What are the three major elements of prosthetic rehabilitation
occlusion
esthetics
phonetics
What three esthetic compositions are related
dental composition
dentofacial composition
facial composition
Esthetic harmony depends on what
equilibrium between distractive elements
What four locations are used for vertical reference lines
bridge of the nose
philtrum
face midline
dental midline
What is the golden proportion
pythagros; 1.618
plato; 1.733
This is regularity in the arrangement of teeth; it must be introduced in the dentofacial composition to create a positive psychological response
symmetry
What four things must be symmetrical
dental midline
maxillary central incisors
maxillary lateral incisors
maxillary canines
What four things affect perspective and illusion
widening and narrowing
shortening and lengthening
contract
shading
This component of a smile can be either high, moderate, or low
lip line
This component of a smile is a hypothetical curved line drawn along the edges of maxillary anterior teeth that has to coincide or run parallel to the curvature of the lower lip; more pronounced in women
smile line
What are the nine components of a smile
lip line smile line upper lip curvature buccal corridor axial alignment and gradation dominance embrasures dental morphology gingival morphology
What are the three characteristics of an embrasure
form
symmetry
progression
What are the three characteristics of dental morphology
contact areas
embrasures
texture
What are the three characteristics of gingival morphology
gingival tissue and racial factor
gingival health and contour
gingival zenith (highest point)
