Preparing for cementation

Conditioning of the restoration and preparation depends on the cementation protocol used, as well as on the luting material. The
following paragraphs describe the basic working steps to prepare for cementation. Please refer to the Instructions for Use of the
corresponding cementation material regarding the detailed processing procedure.

Conditioning of the restoration

Conditioning of the ceramic surface in preparation for cementation is decisive for establishing a sound bond between the
cementation material and the all-ceramic restoration. The following procedure should be used in conjunction with Zenostar
restorations:

Blast the surface of Zenostar restorations with corundum at a maximum pressure of 1 bar (15 psi) before cementation.

Thoroughly clean the Zenostar restoration with water and air-dry it.

Saliva can easily be removed from the restoration by means of Ivoclean (Ivoclar Vivadent).

If you use an adhesive cementation protocol, condition the bonding surface with Monobond

®

Plus.

Conditioning of the preparation

Once the temporary restoration has been removed, thoroughly clean the preparation. Before it is conditioned, the restoration is
tried-in and the occlusion and articulation are checked. If adjustments of the restoration are required, the restoration must be
polished extraorally in these areas before final seating. Any saliva can easily be removed from the restoration by means of Ivoclean
(Ivoclar Vivadent). Conditioning of the preparation depends on the cementation method used and is carried out according to the

respective Instructions for Use.
