Tissue Conditioners Flashcards
What are some examples of types of tissue conditioners?
- powdered polymer (polyethyl methacrylate or isobutly methacrylate)
- liquid (an ester such as butyl phthalate or butyl gylcolate in an alcohol solvent)
KNOW THIS
What is pathognomonic?
(of a sign or symptom) specifically characteristic or indicative of a particular disease or condition
What is the purpose of tissue conditioners?
- improves retention and stability and relieves pressure
- allows the abused tissue to recover
How do you place the tissue conditioner?
- polymer and monomer are mixed to make a gel and then placed in denture
- insert for 5 minutes
- self-curing and slowly polymerizing
- trim the excess
What do tissue conditioners treat?
- chronic denture soreness
- traumatized oral mucosa
- remodeling ridges
What do tissue conditioners allow for?
- allow patient to continue wearing dentures while allowing abused tissue to heal
- sponginess of material absorbs loads and allows tissue to heal
What can happen if tissue conditioners are not renewed?
resin becomes stiff and produces the same tissue abuse that it was placed to treat
How often should tissue conditioners be renewed?
once or twice per week
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
What is a resilient liner?
A group of elastomer polymers
Used in a denture when a protective resilient surface is needed on the intaglio surface: sensitive mucosa, postradiation mucositis, poor supporting tissue, etc.
When should you use resilient liner?
Xerostomia patients
Hypersensitive mucosa
Bruxers
Knife-edge ridge / atrophy

How does tissue change do to dentures?
Stresses of daily function
Changes in general health status
Hereditary factors
Defects in dentures -→ produce changes in tissue form
How often do you need to reline complete dentures?
every 4-7 years after initial insertion
Why do we reline/rebase?
Fit of denture base to the foundation is poor.
Denture is not stable and/or is non-retentive.
Denture base is fractured, discolored, or underextended.
