Operative Exam #
1.How are restorative materials categorized?: direct (inside pt's mouth) &
indi- rect (from lab)
2.Direct restorative materials: fabricated inside pt's mouth
DRRAG
- direct gold
- resin based composite
- resin-modified glass ionomer cements
- amalgam
- glass ionomer cements
3.Indirect restorative materials: lab is involved; fabricated outside of
mouth
CPR
- cast metal alloys
- resin based composite
- porcelain
4.Composition of resin based composite: - matrix
- filler
- coupling agent (holds fillers in matrix)
- initiator (chemicals, photo)
5.Base which other components are added to (made from monomer): matrix
6.Small particles made from fine glass, quartz or silica are added to
improve physical, mechanical and optical properties: filler
7.Produces chemical bond between matrix and fillers: coupling agent
8.Agent responsible for chemical setting (hardening) rxn: initiator
9.Process in which relatively small molecules, called monomers,
combine chemically to produce a very large chainlike or network
molecule, called a polymer: Polymerization / cure / setting
10. is a molecule that can be reacted together with other monomer
molecules to form a larger : monomer, polymer
11.The more fillers you put in to make material stronger, this makes
the material MORE VISCOUS (not fluid!!): filler increases viscosity
12.The viscosity of composite is altered by changing the: resin / filler ratio
13.Flowable composites have less resin and fills irregularities better
because it is less viscous: filler/more resin
14.You want resins to be more for sealants: fluid
15.3M Clinpro Sealant: - unfilled light cured sealant material
- 6% filler by weight
