Glue the directly screw-retained crown
onto the titanium base
Prior to gluing, check to make sure that the crown can be easily placed
on the titanium base. No gap should be visible between the restoration
and the attachment surface of the titanium base.
CAUTION
Observe the manufacturer’s instructions for handling the titanium
base.
The contact surfaces of the titanium base to the implant should not be
sand-blasted or otherwise processed.
The diameter of the titanium base should not be reduced (e.g. by
grinding). Shortening the titanium base is not recommended.
The surfaces of the titanium base intended for gluing to the zirconium
oxide ceramics have to be sand-blasted and cleaned.
Surfaces of the zirconium oxide ceramics and the titanium base to be
glued must be free of dust and grease.
1. Sand-blast the gluing surfaces of the zirconium oxide ceramics and
the titanium base with 50 µm aluminum oxide and up to 2.0 bar.
(The screw channel of the zirconium oxide ceramics is also an
adhesive surface and must be treated accordingly with the
sandblasting technique.)
2. Clean the adhesive surfaces with alcohol or steam. For easier
handling during the gluing process, it is recommended that the
titanium base be screwed into a lab implant or a polishing tool.
3. Cover the hex head of the abutment screw with wax.
NOTICE
Use "PANAVIA™ F 2.0" (www.kuraray-dental.de) extraoral as the
adhesive for connecting the titanium base and the zirconium oxide
ceramics.
4. Apply Alloy Primer (from Kuraray Noritake Dental Inc.) onto the
TiBase adhesive surface in accordance with the manufacturer's
instructions.
5. Mix the glue according to the manufacturer's instructions and apply
it to the titanium base.
6. Press on the customized zirconium oxide ceramics as far as it will
go. Make sure it latches into the rotation and position stops.
7. Remove excess glue immediately.
8. Apply the Airblocker ("Oxygard") to the junction where the ceramic
and titanium surfaces meet and to the screw funnel for final
hardening.
9. Remove residue with a rubber polisher after hardening.
