PROPERTIES     -soft polymers               1) RESILIENCE
               -low Tg                      - sufficiently soft on insertion; adequate cushioning effect
               -app to fitting surface of   - HEAT cure acrylic materials not as soft as the COLD cure INITIALLY. But they retain softness for longer.
               denture                      Later become hard (gradual leaching of plasticizer ino mouth)
               -temporary cushion           -SILICONE MATERIALS remain permanently soft
               -physical process
               -not irritant (not contain   2) WATER SORPTION
               monomer)                     -problems with SILICONES
               -not permanent               -water sorption followed by bacterial growth in the soft lining
               -replaced every 3 days
               (alcohol                     3) BOND STRENGTH TO DENTURE BASE
               evaporates&plasticizer       -adequate for ACRYLIC materials and HEAT cured SILICONE products
               leached out and hardens)     -tendency to peel away from the base in COLD cured SILICONE materials

                                            4) EFFECT OF DENTURE CLEANSERS
                                            -some adversely affected by denture cleansers
                                            -oxygenating cleansers cause surface piting in ACRYLIC linings
                                            -brushing accelerates SILICONE soft linings ti become detached
                                            -soaking in very dilute solution hypochlorite is acceptable way of achieving denture hygiene without
                                            damaging soft lining

                                            Biocompability is of interest     Last longer than mouth cured
                                            (leach out significant amounts
                                            of alcohol&phthalate esters)

But they retain softness for longer. denture Later become hard (gradual leaching of plasticizer ino mouth) -temporary cushion -SILICONE MATERIALS remain permanently soft -physical process -not irritant (not contain 2) WATER SORPTION monomer) -problems with SILICONES -not permanent -water sorption followed by bacterial growth in the soft lining -replaced every 3 days (alcohol 3) BOND STRENGTH TO DENTURE BASE evaporates&plasticizer -adequate for ACRYLIC materials and HEAT cured SILICONE products leached out and hardens) -tendency to peel away from the base in COLD cured SILICONE materials 4) EFFECT OF DENTURE CLEANSERS -some adversely affected by denture cleansers -oxygenating cleansers cause surface piting in ACRYLIC linings -brushing accelerates SILICONE soft linings ti become detached -soaking in very dilute solution hypochlorite is acceptable way of achieving denture hygiene without damaging soft lining Biocompability is of interest Last longer than mouth cured (leach out significant amounts of alcohol&phthalate esters) APPLICATIONS a) Treatment of a) Whre oral mucosa Same as mouth-cured irritated mucosa covering denture- b) Dentures of bearing area is thin patients after b) Where oral mucosa is surgery very sensitive c) Severe undercuts
