Cementation
Preparation of the Celtra restoration
> Clean the restoration with a steam cleaner, in ultrasonic bath or with alcohol.
> Apply 5 % – 9 % hydrofluoric acid etching gel (Available separately, see
manufacturer's complete Directions for Use) to the interior of the restoration
only and allow to soak for 30 seconds.
> CAUTION: Follow manufacturer's precautions. Do not allow tissue or eyes to
come into contact with the acid!
> Remove the hydrofluoric acid as per the manufacturer's instructions.
> Dry the restoration in an air stream. It is recommended
to silanize the etched surfaces immediately.
> At chairside, apply silane only to those surfaces
required for adhesive cementing.
> Allow to soak for 60 seconds. If the silane layer is no
longer liquid, add more silane. Blow-dry in a powerful
air stream. (Recommended material: Calibra
separately, see complete Directions for Use).
