|
Zinc phosphate (4)
|
(Fleck's cement)
-rarely used anymore -very acidic, causes post-op sensitivity/necrosis -very thin, so some like it for gold -or for endo posts |
|
|
ZOE (4)
|
-IRM, Tempbond
-to thick for perm restoration luting -usually used for temps -soothing |
|
|
zinc polycarboxylate (4)
|
-Durelon, ultratemp
-some adhesion to tooth -mainly used as temp -sealer for RCTed toth that won't be crowned |
|
|
Calcium hydroxide salycilate (5)
|
-Dycal, Life
-pulp capping, endo med -temp crowns -high pH and solubility -low strength |
|
|
contemporary permanent luting cements (2)
|
-GI's
-comp resins |
|
|
unmodified GIs (5)
|
-stable tooth bond
-slow set -not as strong (compressive, tensile) as composites -more soluble than comp -good handling, thickness |
|
|
modified GIs (2)
|
-3M (Rely-X), GC America (Fuji Cem/Plus)
-same traits as unmodified, but set much quicker |
|
|
GI tooth bonding
|
-stick to tooth by ionic bonding to tooth minerals
|
|
|
etching before GI (3)
|
-debated
-improves performance -might increase sensitivity |
|
|
Resin luting cements:
uses (6) |
-recommended for all ceramic restorations
-PFM -Gold -endo posts -indirect restoration -Maryland bridges |
|
|
problem w/ dual cure (2)
|
-less color stable
-don't use w/ veneers |
|
|
resin luting cements:
mech of adhesion exception |
-hybrid layer through demin of tooth surface and infiltration of resin in its place
-Rely X UniCem |
|
|
Rely X UniCem:
type bonding |
-self etching resin cement
-unique: acidic side chains form ionic bonds w/ tooth (like GIs) |
|
|
rubber dam?
|
-yes for total etch resin cements
|
|
|
easier to clean?
|
-GIs
|
|

-dual cure, self cure resin -self cure resin, GI |
|
|
prob w/:
