All ceramic crown cementation. Successful application of all ceramic materials depends on the practitioner s ability to select both the appropriate material and cementation protocol that satisfy the patient s needs and expectations. All ceramic restorations can be crowns bridges inlays onlays and veneers. In relation to final cementation of all porcelain restorations it is important to note that the materials used for this should exhibit shear thinning a reduction in viscosity with applied pressure to minimize fracture of the restoration upon seating. 11 12 critical usage factors and idiosyncrasies make the use of resin cements for routine procedures more difficult and these cements are not a guarantee against postoperative.

Trial fit the restoration and clean thoroughly. Today s modern cement is designed to provide excellent marginal integrity which helps to compensate for any tiny discrepancies between the tooth preparation and the restorative material. They are essential for cementation of many all ceramic crowns to prevent crown fracture 10 but are also useful in low retention conventional crown or post situations. All temporary cement residue.

These restorations are typically cemented adhesively using glass ionomer cements and bonded adhesive composite resin cements. Bonding conventional all ceramic crowns. A primer is applied for one minute enabling the resin based cement to bond to the all ceramic crown. The new self curing multilink hybrid abutment was especially developed for the cementation of lithium disilicate glass ceramic onto titanium bases ips e max hybrid abutments and ips e max hybrid abutment crowns.

Glass ceramic crown cementation step 1 etch with hydrofluoric acid after try in. When bonding the surface of the restoration is etched with 5 hydrofluoric acid for 20 seconds before being thoroughly rinsed. Pre fabricated and cast posts and pins. Sometimes it is necessary to precondition the tooth but this is dependant.

Step 6 remove provisional restoration. Speedcem plus the self adhesive dual curing luting composite is even easier to use than a conventional cement. All ceramic is a catch all category but it really describes restorations fabricated without cast metal. Mechanically clean prepared tooth e g.

2 indicated for final cementation of. Metal and porcelain fused to metal crowns bridges inlays and onlays. Additionally the cement available for different types of all ceramic crowns require specific surface treatments to be used which optimizes bonding. Cementation of ceramic veneers will be discussed in further in chapter 12.
