This column addresses the bonding of zirconia restoration offering a handful of useful tips. [Cindy Chambers](https://blog.ddslab.com/author/cindy-chambers) Nov 20, 2021 --- Recent technological advancements have led to [zirconia](https://www.ddslab.com/zirconia-in-dentistry/) becoming the most requested material for fixed restorations in Dentistry. This column addresses the bonding of zirconia restoration offering a handful of useful tips. Zirconia is an incredibly strong material with a flexural strength five times greater than other ceramics. It can now be applied to a variety of clinical indications including single crowns, implants, endodontic posts, and both anterior and posterior dental restorations. The evolution of translucent or esthetic zirconia materials encourages its use without visual limitations.  Zirconia is a ceramic, but it is not an etchable ceramic, nor does it contain silica. [Zirconia](https://go.ddslab.com/zirconia-ebook) cannot be etched or silinated, so the bonding procedure is different than the one used for felspathic porcelain or lithium disilicate. One of the common errors clinicians make is treating zirconia like it is lithium disilicate when bonding zirconia. ## Zirconia Bonding Tips ### 1. Prepare the intaglio of the crown before cementation. ![Tip 1 Prepare the intaglio of the crown before cementation](https://blog.ddslab.com/hs-fs/hubfs/Images/Blog_Images/Tip%201%20Prepare%20the%20intaglio%20of%20the%20crown%20before%20cementation.jpg?width=565&name=Tip%201%20Prepare%20the%20intaglio%20of%20the%20crown%20before%20cementation.jpg)Dental zirconia bonds to phosphates. A core problem is that saliva contains a significant amount of phosphate. This means that the presence of saliva contaminates the surface of zirconia restorations and hinders the development of a strong bond due to the depletion of bonding sites. ![Ivoclean Dental Cleaning Paste ](https://blog.ddslab.com/hs-fs/hubfs/Images/Blog_Images/Ivoclean%20Dental%20Cleaning%20Paste%20.png?width=200&name=Ivoclean%20Dental%20Cleaning%20Paste%20.png)During try in the zirconia is exposed to saliva. So before performing the final bonding it is critical to decontaminate the zirconia intaglio. Simply rinsing out the saliva does not remove the phosphate groups that are bonded to the zirconia. Use an alkaline gel such as potassium hydroxide solution that can remove saliva that can contaminate the crown, thus reducing the bond failure. There are several on the market, one example is Ivoclean from Ivoclar Vivadent. ### 2. Consider zirconia primers to increase the bond strength.![Tip 2 Consider zirconia primers to increase the bond strength](https://blog.ddslab.com/hs-fs/hubfs/Images/Blog_Images/Tip%202%20Consider%20zirconia%20primers%20to%20increase%20the%20bond%20strength.jpg?width=824&name=Tip%202%20Consider%20zirconia%20primers%20to%20increase%20the%20bond%20strength.jpg) Since conventional silane coupling formulas cannot bind to metal-oxide ceramics, ceramic primers have unique adhesive monomers that allow them to bond to zirconia. This is especially recommended when preps are not meeting the recommended prep requirements for height and angle of axial walls. When your prep is short this can make the difference whether it stays bonded or not. Monobond Plus from Ivoclar Vivadent, and Z-Prime Plus from BISCO are just 2 examples. ### 3. Utilize self-adhesive dual-cure resin cement which is more effective than regular cements for zirconia crowns and bridges.![Tip 3 Utilize self-adhesive dual-cure resin cement which is more effective than regular cements for zirconia crowns and bridges](https://blog.ddslab.com/hs-fs/hubfs/Images/Blog_Images/Tip%203%20Utilize%20self-adhesive%20dual-cure%20resin%20cement%20which%20is%20more%20effective%20than%20regular%20cements%20for%20zirconia%20crowns%20and%20bridges.jpg?width=824&name=Tip%203%20Utilize%20self-adhesive%20dual-cure%20resin%20cement%20which%20is%20more%20effective%20than%20regular%20cements%20for%20zirconia%20crowns%20and%20bridges.jpg) I hope you find these tips useful.
