7 - 4/3: Tissue Conditioners Flashcards
What is pathognomonic?
(of a sign or symptom) specifically characteristic or indicative of a particular disease or condition.
“body image disturbance is pathognomonic of anorexia nervosa”
What are examples of powdered polymers?
Polyethyl methacrylate or isobutyl methacrylate
What is a liquid tissue conditioner?
An ester (butyl phthalate or butyl glycolate) in an alcohol solvent
What does lining the intaglio surface of a denture with a tissue conditioner improve?
Retention and stability and relieves pressures
- this allows abused tissue to recover
How are polymers and monomers used as tissue conditioners?
Polymer and monomer are mixed to make a gel, then placed in denture -> insert for 5 minutes
What are characteristics of tissue conditioners?
Self-curing and slowly polymerizing
Versatile and easy to use
What are tissue conditioners used to treat?
Chronic denture soreness
Traumatized oral mucosa
Remodeling ridges
What do tissue conditioners allow the patient to do?
Continue wearing dentures while allowing abused tissues to heal
What is the benefits of the spongy material of tissue conditioners?
Material absorbs loads to the underlying residual ridge and allows the tissues to heal during function
When is there a loss of resiliency?
As the plasticizer leaches out - resin becomes stiff
When should tissue conditioner material be renewed?
Once or twice per week (if treating irritated tissue)
What happens to tissue conditioners if not renewed?
The resin becomes stiff and produces the same tissue abuse that it was placed to treat
What are the uses of tissue conditioners?
- Prevent or treat chronic denture soreness
- Stabilize temporary record bases
- Stabilize immediate dentures during healing
- Final impression material for functional impressions
