Materials and Techniques: Impressions
pt 1
____________ resistance to flow
A. viscosity
B. tear energy
C. elastic recovery
D. dimensional stability
E. hydrophilic
F. hydrophpbic
G. thixotropic
H. yield strength
A (different viscosities for different uses -- tray material is thicker and has
more support, syringe material is lower viscosity and captures the details and
is more easily deformed when patient is doing functional movements)
(everything has different viscosities for different uses)
_____________ = resistance of material to tear upon setting and removal
from mouth
A. viscosity
B. tear energy
C. elastic recovery
D. dimensional stability
E. hydrophilic
F. hydrophpbic
G. thixotropic
,H. yield strength
B (some materials will tear before it deforms and others will deform before it
tears)
Alginate:
A. tears before it deforms
B. deforms before it tears
A (whereas VPS gets its form back once it's removed from the undercuts)
_____________ = the ability of a material to return to its original dimensions
without significant distortion upon removal of the mouth
A. viscosity
B. tear energy
C. elastic recovery
D. dimensional stability
E. hydrophilic
