industry Ortho Tribune U.S. Edition | NESO & PCSO 2016 6 Ad By Reliance Staff F our years ago, Reliance re- leased a revolutionary prod- uct, Assure® Plus. On top of bonding to every artificial surface found in the mouth, one of the most attractive features of Plus, according to the com- pany, is the ability to eliminate the in- traoral use of hydrofluoric acid to etch ceramic crowns. To the naked eye, all “ceramic” sub- strates look similar intraorally. The un- fortunate fact is a “ceramic” surface can potentially be fabricated from lithium disilicate, porcelain, layered zirconia, monolithic zirconia and so on. In previ- ous years, bond strength values were very poor if porcelain conditioner was applied to a zirconia surface; thus the cli- nician had to be confident the substrate was porcelain. According to Reliance, there is news on the ever-developing situation of bonding to ceramic crowns. Extensive tests have shown that roughening or even sand- blasting are no longer needed when us- ing Reliance Porcelain Conditioner and Assure Plus. Furthermore, the task of dif- ferentiating zirconia from porcelain is unnecessary. When confronted with bonding to a crown (porcelain or zirconia), the steps are as follows: 1. Prophy, rinse and dry 2. Apply one coat of Reliance Porcelain Conditoner, wait 60 seconds and air dry 3. Apply one coat of Assure Plus, air dry and light cure 4. Apply bracket with paste and cure Far too often we take for granted the benefit of a thorough prophylaxis. If adapting the above bonding modality, a thorough prophy is absolutely impera- tive to an acceptable bond strength. The air drying of the active ingredient in Re- liance Porcelain Conditioner now allows the clinician to skip the substrate iden- tification. If the substrate is porcelain, the silane will bond to the glass filler. If the surface is zirconia, the drying and 60-second wait time allow the silane to go unutilized without interfering with Assure Plus. Artificial but not ceramic? The remain- ing substrates (gold, amalgam, stainless steel, composite, acrylic) are handled with the following protocol: 1. Prophy, rinse and dry 2. Sandblast, rinse and dry 3. Apply one coat of Assure Plus, air dry and light cure 4. Apply bracket with paste and light cure Much like Assure regular, Assure Plus built its foundation on being the only primer to bond to wet or dry, normal or atypical surfaces. According to the com- pany, atypical enamel (hypocalcified, fluorosced, aprismatic, etc.) presents a serious challenge if the clinician is not ” See SKIP, page 8 Skip the roughening and the sandblasting with Assure Plus When using Reliance Porcelain Conditioner and Assure Plus, roughening or even sandblasting might no longer be needed, according to Reliance.
