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 minutes2,3 for a thin-walled crown.
For easy shade matching, the material is available in eight different shades and two block sizes designed for crowns and three-unit bridges4 to match the VITA® classical shades. Additionally, due to its low minimum wall thickness of 0.8 mm, dentists are able to carry out less invasive preparations and preserve more tooth structure.
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. This product will be available for sale in the US on May 1, 2019.
