Cleaning, Cementation and Removal of Restoration Cleaning the Restoration After Try-in The Zenostar® restoration must be cleaned after intraoral try-in and before cementation. Ivoclean™ is a universal cleaning paste that effectively cleans the bonding surfaces of all types of indirect restorations after intraoral try-in. While phosphoric acid may be used to clean the surface of glass ceramic restorations, its surface-deactivating effect on zirconium-oxide ceramics and base metal alloys inhibits bonding. Cementation of Restoration Zenostar restorations can be cemented both conventionally and by means of an adhesive cement such as Multilink Automix®. Multilink Automix is a truly multi-purpose adhesive cement, indicated for cementation of indirect restorations (inlays, onlays, crowns, bridges, and posts) made of all types of restorative materials including zirconia, due to its self-curing with light-curing option. Multilink Automix features patented, hydrolytically stable acidic monomers generating high immediate bond strengths and durable adhesion for long-term security. Removal of Restoration Zirconia restorations and zirconia crowns can be removed in a few simple steps. Preparing the Restoration for Removal If the crown has been veneered using the one-layer technique, then the crown is first made accessible by removing the one-layer ceramic on the occlusal surface with a water cooled diamond bur. In the next step the underlying zirconia crown is carefully perforated, keeping a distance of 0.5 mm from the ceramic veneer. This is important in order to prevent chipping or cracking in the ceramic veneer as a result of overheating. In order to seal the access cavity once the endodontic treatment is complete, we recommend filling the trepanation hole with a composite adhesive. Removing a Zenostar® Zirconia Crown There are two different ways of removing zirconia crown from the tooth stump. We recommend the following method: Use a diamond bur to slit open the axial wall of the zirconia crown in a lingual-labial direction (using plenty of cooling water). Then use a crown remover to lift the crown off without damaging the supporting prepared tooth.
