1
Q
What are examples of temporary materials?
A
- PMMA = Jet
- PEMA = Trim II / Snap
- Bis-acryl Composite = Protemp4 / Quicktemp
- UDMA = Provipont DC
2
Q
What are the positives of using PMMA as a temporary material?
A
- self curing
- good marginal fit
- good transverse strength
3
Q
What are the negatives of using PMMA as a temporary material?
A
- poor abrasion resistance
- high shrinkage
- high thermal release
- free monomer may be toxic
4
Q
how do PMMA and Bis-acryl(ate) composite differ?
A
PMMA = monofunctional monomer (one C=C bond)
Bis-acryl(ate) Composite = bifunctional monomer ( two C=C bonds)
