Week 1 - intro to composite restorations Flashcards
types of aesthetic restorative material (tooth colored)
ceramic inlays/onlays silicate cement acrylic resin conventional glass ionomers composite
ceramic inlays/onlays
fabricated in lab
can be done chairside with CAD/CAM
silicate cement
no longer used
used to use for anterior restorations
acrylic resin
use in areas where temperature change, abrasion, and stress are LIMITED because-
low strength, high polymerization shrinkage
conventional glass ionomers
release fluoride for anti-cariogenicity
used for root surface caries
DO NOT use in occlusal areas
why are CGI bad for use in occlusal areas?
low resistance to wear and low strength
two types of glass ionomers
resin-modified
compomer
resin modified GI
resin added to GI to increase physical properties
can be light cured
acid-base setting rxn
compomer GI
polyacid modified composite
composite with some GI components
Composite components
resin + inorganic filler for increased physical properties
what kind of bonding agent used for composites?
silane bonding agent
types of composites
macrofill microfill hybrid composites nanofill composites packable composites flowable composite
most popular type of composite used today
nanofill composite
nanofill composite
small filler particles
highly polishable
packed tight for physical properties
packable composites
most viscous
for proximal contact restorations
mimic amalgam
