3M Raises the Bar in Same-Day Dentistry

New chairside zirconia optimizes strength, esthetics, process speed 

for crowns and bridges

 

ST. PAUL‚ Minn. – (Feb. 4, 2019)– Chairside CAD/CAM dentistry has promised convenience since its inception, including the advent of the single-visit crown; however, with convenience can come compromise. While software and equipment technology has advanced continuously, materials have struggled to keep pace. A strong material might appear lifeless in the mouth, while a more esthetic material may crack or fracture. Recognizing the need for a well-balanced alternative that maximizes new high-speed sintering technology, 3M is introducing 3M™ Chairside Zirconia – a new CAD/CAM zirconia block optimized for the fast-sintering CEREC® SpeedFire Furnace1.  The new block offers an optimal blend of high strength and esthetics to go along with a fast sintering time of approximately 20 minutes2,3for a thin-walled crown.  

            “The esthetics and better sintering time of 3M™ Chairside Zirconia have made this my go-to zirconia material,” said Daniel Butterman, DDS. “It polishes very easily and has a good level of translucency. I see no need to glaze this material.”

            For easy shade matching, the material is available in eight different shades and two block sizes designed for crowns and three-unit bridges4to match the VITA® classical shades. Additionally, dueto its low minimum wall thickness of 0.8 mm, dentists are able to carry out less invasive preparations and preserve more tooth structure.

            “The overall promise of chairside dentistry has always been efficiency in a single-visit appointment,” said Karen Burquest, Global Business Leader, 3M Oral Care. 

“Our new zirconia is designed for high-speed sintering to deliver even more efficiency without compromises in strength or esthetics.” ​

            3M Chairside Zirconia offers a high flexural strength option of over 800 MPa, and has a fracture toughness that meets stringent ISO standards. This gives it ideal strength for single-unit crowns and three-unit bridges. 

             The cementation process is simplified, as well, with the option to use either 3M™ RelyX™ Luting Plus Resin Modified Glass Ionomer Cement or 3M™ RelyX™ Unicem 2 Self-Adhesive Resin Cement. These easy to use, reliable cement options offer trusted solutions for your chairside zirconia needs.

            3M Chairside Zirconia will be featured and available for pre-ordering at the Chicago Midwinter meeting February 21-24, 2019. 3M Chairside Zirconia will officially launch at IDS in March. Product will be available for sale in the US on May 1, 2019.

This is an awesome addition to the chairside block line...it HAS a definite place in our office!

Does this have the same kind of thickness caveat as Katana? How does the translucency compare with Katana or something like e.max LT? 


Other than the bridge block, I don’t see any benefit over Katana.

Katana will be faster for crowns that have no walls over 3mm thick, if the crown is thicker than that, 3M will be faster.

Unless I am reading it wrong, which is VERY possible, it looks like they are saying you can get 800mpa with traditional cementation. If it looks the same as katana then the advantage is you are not going "off-label" cementing it in. Manufacturer for katana only recommends bonding at this time to acheive similar mpa.

A little higher MPA, 10 minutes less of sintering ( I have yet to use the 18 minute sintering for 6 Katana restorations since the update) and you do not have to bond it like Katana, just simply lute it with RMGI assuming proper retention. 


Any post-op photos...?


Grady, I’m doing a lecture for 3M this weekend so was holding back on posting some images until I did the event here. I’ll get a few pre and post op images prob tomorrow.


Looking forward to that


Here are 2 before and after cases with the 3M zirc.  I was up at 3M's wonewok conference center with lots of dentists and researchers from around the country and it was awesome.  Had to present to those dentists about the new chairside zirconia and it is always nerve wracking to speak in front of that kind of crowd.  They seems to like what we showed so I was happy about that.  In the first case the pt had an open contact between 14 and 15.  I took the old gold crown out an put in a bleach shade zirc.  I used the meisinger twist polishers to pre polish and then just the fine and extra fine to post polish.  This first case is immediate cement so sorry for a bit of the rough buccal tissue

 

the second case the pt had a crack on 18 D and we decided to crown it and protect it from possible fracture.  This was a c1 shade with the cita easy shade.  Not an easy shade to match.  I was happy about how it looked against the shade tab.  

 

it seems pre polishing seems to make it look less opal.  in the second to last pic, that is prepolished out of the oven.  I then went over it with the fine and extra fine to get a better gloss.  I still use a ton of emax but I have to say I'm enjoying using chairside zirconia more and more.
