Possibilities for Cementation
Possibilities for esthetic cementation are decisive for the harmonious shade effect of an all-ceramic restoration. Depending
on the indication, IPS e.max ZirPress restorations can be seated using either adhesive, self-adhesive or conventional
cementation.
– For the adhesive cementation of IPS e.max ZirPress restorations, Variolink ® II, Variolink ® Veneer or Multilink ® Automix are
the ideal composites.
– SpeedCEM is available for the self-adhesive cementation of IPS e.max ZirPress.
– We recommend using the glass ionomer cement Vivaglass ® CEM*, for the conventional cementation of IPS e.max ZirPress.
*The range of available products may vary from country to country.
Short definition of the different cementation methods
• Adhesive cementation
With adhesive cementation, the bond is also created by static friction, but primarily by the chemical and/or micro-
mechanical bond between the luting material and the restoration, as well as between the luting material and the
preparation. Given the chemical and/or micromechanical bond, retentive preparation is not required. Irrespective of the
cementation material, special adhesive systems are used on the preparation to generate the micromechanical bond with
the dentin and/or enamel.
Adhesive cementation results in enhanced ”(overall) strength” of the seated all-ceramic restoration.
• Self-Adhesive Cementation
The cementation material features self-etching properties to the tooth, which is why no additional special conditioning of
the tooth surface is necessary. Hence, the adhesion of the restoration is partially achieved by a micromechanical and/or
chemical bond. In order to achieve sufficient bonding strength values, retentive preparation is recommended. Self-
adhesive cementation does not result in enhanced ”(overall) strength” of the seated all-ceramic restoration.
• Conventional Cementation
In the conventional cementation technique, the bond is achieved nearly exclusively through mechanical friction between
the cementation material and the restoration as well as between the cementation material and the preparation. In order
to obtain the required mechanical friction, a retentive preparation showing a preparation angle of approximately 4 – 6° is
required.
