ormocers

Question 1

What is an ormocer?

Answer 1

modified ceramic technology
monomer free matrix
3 crossed linked co polymers
inorganic silanated filler particles provide polymerisation opportunities

Question 2

What are the 3 components of an ormecer?

Answer 2

silicones
organic polymers
ceramic glasses

Question 3

What provides polymerisation opportunites?

Answer 3

inorganic silanated filler particles

Question 4

who does silicone component allow?

Answer 4

elasticity
surface energy
gas permeabiltiy

Question 5

What do organic polymers provide?

Answer 5

toughness
flexibility
processabiltiy

Question 6

What do ceramic glasses provide?

Answer 6

hardness
chemical/thermal stability
transparency

Question 7

how are ormocers manufactured?

Answer 7

commence with build up of inorganice network
hydrolysis of modified si alkenoates
condensation

Question 8

how are organic matrix formed?

Answer 8

heat or Uv initiated reaction to produce inorganic co polymer

Question 9

What is the result of the ormecer?

Answer 9

less shrinkage

no residual monomers- no chair side repair
