RMGIC's Flashcards
what is a RMGIC
GIC with resin components
what is the difference between RMGIC and GIC
less water - replaced by HEMA
modified polyacid with side chains
- double C bond can break and polymerise
PROS (7) 3 UP, 1 ACROSS, 2 DOWN
aesthetics
fluoride release
shorter setting time
less moisture sensitivity
higher bond strength
easier to use
resistant to dessication
What is RMGIC used for?
cervical and root lesions
as a base
abfraction lesion
Issues with HEMA
known contact allergen to eyes
- use gloves and no-touch technique
What is a Compomer?
polyacid-modified resin composite resins
contain acidic and acrylate groups
basc a modified composite
how is a compomer set?
light cure = polymerisation
water uptake
acid+base reaction
= further cross linking of matrix
PROS of compomers
handling
good command set
strength
CONS of compomers
adhesion
low fluoride release
needs bonding agent
