STEP BY STEP Bonding procedure DIGITAL WORKFLOW OF THE INTRAORAL BONDING PROCEDURE Elos has performed a study on the cementation process looking at a variety of parameters and how they affect the retention strength. The findings of the study are used in this guide. This procedure describe the workflow for intra oral bonding to achieve a passive fit with Elos Accurate ® Hybrid Base™ Non-Engaging. We have used Panavia V5 from Kuraray Noritake in this guide which is approved for Elos Accurate Hybrid Bases for both the EU and US market. Another approved bonding agent for intra oral cementation is RelyX™ from 3M. Key takeaways from study: Do not use steam to clean either restoration or Hybrid base. Do not blast the Hybrid Base. 1. Blast the internal geometry of the milled re- storation connecting to the hybrid bases with 50 µm aluminum oxide (AI2O3) and with a pressure of 2 bar. Sandblasting of the Hybrid Base is not allowed as it might reduce retention of the bonding. Gently remove residue with oil free compres- sed air. 2. Either clean with IPA or Katana Cleaning: IsoPropyl Alcohol (IPA). Clean the surface of the Hybrid Base and the restoration thoroughly with IPA 99% alcohol. Do not use steam to clean the Hybrid Bases or restoration as it will reduce the retention of the bonding. Handle with gloves from this point. 3. Cleaning: KATANA™ Cleaner. Rub surfaces on Hybrid Base and restoration for 10 sec. rinse with clean water or dry gently with oil free compressed air. Do not use steam to clean the Hybrid Bases or restoration as it will reduce the retention of the bonding. Handle with gloves from this point. 4. Position the Hybrid Base in the restoration so that the Guide Grip™ and the U-shape align with the screw channel for correct access for the Elos Accurate ® Hexalobular™ screw. The Guide Grip™ stabilizes the Hybrid Base in the restoration and avoids falling off. The offset is preset in the Elos Accurate Library to achieve an average gap of 40µm. 5. I nstall the monolithic zirconia bridge with the Elos Accurate Hybrid Base Non-Enga - ging on the abutments, torque about 10Ncm (hand-torque). 6. Apply the CLEARFIL™ CERAMIC PRIMER PLUS in the zirconia bridge restoration. Let it air dry or gently dry with oil free compres - sed air.
