G. Adhesive cementation of the
restoration
Preparation of the core and the remaining tooth structure:
– Remove the temporary and clean the core with a polishing
brush and pumice or with prophylactic paste (eg Proxyt).
– Ensure adequate relative isolation. Prevent contamination
with saliva. If possible, use a rubber dam.
– Etch enamel areas with 37% phosphoric acid (eg Total
Etch) for 15–30 seconds. Rinse with water spray and dry.
Depending on the dentin bonding system used, the dentin
may also be etched. Etching is optional when using Syntac
Classic, but compulsory when using Excite DSC.
– Apply Monobond S on the ceramic build-up and let it react
for 60 seconds. Distribute with blown air.
When using Syntac Classic:
– Apply Syntac Primer on the enamel and dentin, let it react
for 15 seconds and blow dry with air.
– Apply Syntac Adhesive on the enamel and dentin, let it
react for 10 seconds and blow dry with air.
– Apply Heliobond on the enamel, dentin and build-up and
disperse to a thin layer with blown air; do not light-cure.
When using Excite DSC:
– Etch with 37% phosphoric acid (eg Total Etch): enamel for
15–30 seconds, dentin for 10–15 seconds. Then, rinse and
dry.
– Apply Excite DSC on the enamel, dentin and the post
build-up, gently agitate the adhesive onto the surfaces for
15 seconds and disperse it to a thin layer using an air
syringe; do not light-cure
.
