Photoinitiaitor
What is a Compomer?
POLY ACID MODIFIED RESIN COMPOSITE
What features of the GIC do Compomers have?
Silica/alumni/CaF filler
What do Compomers contain?
Resin with COOH groups Hydrophilic monomer: aid transport of water and fluoride eg glycerol dimethacrylate Fillers Photo activator UBMA
T/F Compomers exhibit fluoride release?
T
T/F Compomers can be recharged with fluoride?
T
Early ones couldn’t
T/F Compomers adhere to tooth
F need a bonding agent
How do Compomers set?
Polymerisation mainly and some acid base
T/F water is needed for the set of Compomer?
T
Where is the water obtained from?
From the oral environment
What is water needed for?
To mobilise the F ions
T/F Compomers do not have setting shrinkage?
F
Since they are polymers
T/F Compomers have inferior properties to composite?
T
T/F Compomers can be used in high load bearing areas?
F
T/F Compomers can expand ?
T
Due to water sorption
