Extra on Luting Cements Flashcards
how are composite luting agents cured
dual or light
how do composite luting agents bond to compose
via micromechanical to rough surface and also chemical via C=C bonds
how does composite luting agents bond to porcelain
with the help of a silane coupling agent which is applied to the hydrofluoric acid etched porcelain surface
how does a silane coupling agent work
via C=C bonds with the composite resin luting agent and oxide bonds to the porcelain
when would you use a light cured composite luting agent
if the restoration placed is thin
when would you use a dual cured composite luting agent
when the restoration is thick
how are metal surfaces roughened to aid bonding
etching and sandblasting
why do we still need a chemical bond after sandblasting
because sandblasting does roughen the surface but does not give the undercut surface of etching
what chemicals helps to bond to non-precious metal
MDP and 4-META
what do MDP and 4-META have to help them bond to metal
acidic end which reacts with metal oxide and renders the surface hydrophobic
what type of cured material is used to bond to metal
dual curing
some materials have MDP built into them, what material has this and what type of cure is this
panavia
anaerobic self cure
what is GIC used to cement
MCC
metal post
zirconia crown
gold
what is light cure composite resin cement and DBA used to cement
veneer
what is dual cure composite and DBA used to cement
fibre post
composite inlay
porcelain inlay
