Components of Complete Dentures Flashcards
what are the components of a complete denture
denture base
flange
border
teeth
what are the different denture surfaces
fitting surface
polished surface
occlusal surface
what are the two objectives of complete dentures
comfort and preservation of supporting structures
provide adequate masticatory function
what are three factors affecting the success of a complete denture
retention
stability
support
what is retention
the resistance to displacement of the denture base away from the ridge
what are the four factors that affect retention
physical
anatomical
physiological
mechanical
what is adhesion
the forces of attraction between dissimilar bodies in close contact
what is cohesion
forces of attraction between similar bodies in close contact
what anatomical features affect denture success
shape of edentulous area
undercuts
anatomy of border tissue
what are physiological factors
neuromuscular control
viscosity and volume of saliva
what are mechanical factors
balanced occlusion
contour of polished surface
position of the occlusal plane
position of teeth in respect to ridge
where should lower posterior teeth be positioned on a denture
directly above the lower residual alveolar ridge
what does the extra oral relationship record
tooth show
lip support
smile line
incisal relationship
what is the reference plane for the occlusal plane
ala-tragus line
