Replacing anterior teeth with a treatment provisional can be a esthetic nightmare if clasps are all you have for retention. Versacryl offers lingual clasping options for those situations where a facial clasp just wont cut it. For a virtually unbreakable provisional, try the vacuum formed surgical tray material as a frame option.

1. TISSUE SOFT/RESILIENT LINING MATRIALS
CONDITIONERS
ACRYLIC SILICONE
COLD-CURED HEAT-CURED / COLD-CURED HEAT-CURED
TEMPORARY PLASTICIZED A.R PERMANENT PERMANENT
Mouth-cured PERMANENT
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)
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
2. c) Functional d) Congenital/acquired
impression defects of palate
materials e) Bruxism patients
COMPOSITION POWDER (no initiator) POWDER POWDER Same to heat-cured - Siloxane polymer
- Polyethyl - Poly (ethyl - Acrylic type - Silica
metacrylate metacrylate) copolymer / - Stannous - Peroxide initiator
(PEMA) - Peroxide initiator polyethyl octoate
LIQUID (no monomer) methacrylae (catalyst)
- Ethyl alcohol LIQUID - Benzoyl To initiate
(solvent) - Methyl metacrylate peroxide polymerization
- Aromatic ester; - Ehanol & aromatic
butyl phthalate esters LIQUID
(plasticizer) - Tertiary amine - Acrylic
activator monomer
(methyl
metacrylate)
- Plasticizer;
dibutyl
phthalate
MANIPULATION -Mixed material applied Same as tissue conditioners Similar to denture relining
to fitting surface of -old denture provided by a relief space
denture -alginate imp is obtained
-Denture seated in -packing the soft liner in space by compression technique
patient’s mouth -curing (at room temp/heat-cured)
-Inspect denture&soft Not easy to finish and polish
tissues after 2-3 days
-cast(if functional imp)
