7. Cement Requirements
Lack of post-operative sensitivity
Strong bond and good seal
-to the tooth and to the restorative material
Easy placement and clean-up
Esthetics compatible with the restorative
material
Minimal film thickness
Radiopaque (posterior)
8. “Total-etch”
with
Resin Cement
Powder liquid ceramic
or
Pressed ceramic restorations
9. “Tack &
Wave”
Cementation
Veneers and anterior crowns
73. Adhesion to the
restoration
Ceramist etches in lab
Clinician cleans internal surfaces
with phosphoric acid
Rinse and dry thoroughly
Apply Silane coupling agent
Apply dual-cure adhesive resin to
internal of restoration
74. Adhesion to the
restoration
Ceramist etches in lab
Clinician cleans internal surfaces
with phosphoric acid
Rinse and dry thoroughly
Apply Silane coupling agent
Apply dual-cure adhesive resin to
internal of restoration
102. Advantages of
Single Component self-adhesive” cement
Good physical properties
Some adhesive properties
Very, very easy to use
103. Disadvantages of
Single Component self-adhesive” cement
Mediocre bonds to dentin and
enamel
Questionable long term enamel
bonds
Questionable bonds to
restorative substrate

109. When do I use what?
Non-core supported ceramic:
“Total etch”
Core-supported Ceramic
Minimal retention and resistance form?
“Total-etch” with dual cure resin cement
Adequate retention and resistance?
“self-adhesive” resin cements
