elastomeric

means having elastic or rubberlike qualities

extremely accurate impression

elastomeric impression materials are used when an [?] is essential

elastic, rubber like

elastomeric means having [?] or [?] qualities

base and catalyst

as a catalyst, elastomeric impression packages as?

catalyst

also known as accelerator

accelerator

catalyst is also known as?

light bodied

regular and heavy bodied

forms of elastomeric impression

syringe type/wash type

light bodied elastomeric impression is also known as?

tray type

regular and heavy bodied elastomeric impression material is also known as?

regular and heavy bodied

form of elastomeric impression that is THICKER

light bodied

this material is used because of its ability to FLOW in and about the DETAILS of the prepared tooth

special syringe/extruder

used to place the light bodied material on and IMMEDIATELY AROUND the prepared teeth

regular and heavy bodied elastomeric impression material

Their stiffness help to FORCE the light bodies material into CLOSE CONTACT with the prepared teeth and surrounding tissues

stiffness, close contact, prepared teeth and surrounding tissues

the [?] of regular and heavy bodied elastomeric impression material help to FORCE the light bodies material into [?] with the [?]

flow, details

light bodied material is used because of its ability to [?] in and about the [?] of the prepared tooth

initial and final set

curing stages of elastomeric materials

initial set

this curing stage results in stiffening of the paste

initial set

this curing stage is the only time when the material can be manipulated

elastic properties

in the initial set stage, there is no appearance of?

stiffening

initial set stage results in [?] of the paste

final set

this curing stage begins with the appearance of elasticity

appearance of elasticity

the final set stage begins with the?

solid rubberlike mass

in the final set, there is a gradual change to a

final set

in this stage there is a a GRADUAL CHANGE to a SOLID RUBBERLIKE MASS

1, 24

the final set stage occurs from [?] to [?] hours
