Tissue Conditioners Flashcards
powdered polymer
polyethyl methacrylate or isobutyl methacrylate
liquid
an ester (butyl phthalate or butyl glycolate) in an alcohol solvent
tissue conditioners
lining the intaglio surface of a. denture with a conditioners improves retention and stability and relieves pressures. this allows the abused tissue to recover
Polymer and monomer are mixed to make a
gel, then placed in denture -→ insert for
5
minutes.
conditioners (2)
Self-curing & slowly polymerizing
Versatile and easy to use
used to treat (3)
Chronic denture soreness
Traumatized oral mucosa
Remodeling ridges
allow pt to continue
wearing dentures while allowing abused tissue to heal
the sponginess of the material absorbs loads to the underlying residual ridge and allows the tissues to heal during
function
loss of resilliency occurs as the
plasticizer leaches out -resin becomes stuff
material should be renewed
once or twice per week if treating irritated tissue
If not renewed, the resin becomes
stiff and
produces the same tissue abuse that it was
placed to treat
tissue conditioner uses (4)
Prevent or treat chronic denture soreness
Stabilize temporary record bases
Stabilize immediate dentures during healing
Final impression material for functional
impressions
resilient liners
A group of elastomer polymers
Used in a denture when a protective
resilient
surface is needed on the intaglio surface:
sensitive mucosa,
postradiation mucositis,
poorsupporting tissue, etc
resilient liners (4)
Xerostomia patients
Hypersensitive mucosa
Bruxers
Knife-edge ridge / atrophy
Are heat-processed to the denture base as a
“–” procedure
