compomers

Question 1

what are compomers

Answer 1

composite plus glass ionomer
polyacid modified composite resin
similar chemistry to composite resins
also has dimethacrylate monomer and an ion leachable glass filler

Question 2

Setting reaction compomers

Answer 2

free radical polymerization
no chemical bond to tooth structure
low levels of fluoride release
delayed acid base reaction using water from tubules and absorption

Question 3

advantages of compomers

Answer 3

easy to place and polish
some f release
more esthetic than glass ionomer
better mechanical properties than glass ionomer

Question 4

disadvantages of compomers

Answer 4

inferior properties to composites (decreased fx toughness
less f release than glass ionomer
less color stability than composites due to water absorption

Question 5

What are giomers

Answer 5

resin based restoratives with pre reacted glass ionomer particles

Question 6

how do goiters cure

Answer 6

free radical

no chemical bond to tooth structure

Question 7

indications for giomers

Answer 7

clinical trials showed no difference in class V lesions to microfilms but not in class 1 and 2
