DENTSPLY Crypton Cobalt[11] (2013)Cobalt Chrome (non-precious metal)4 sizes, for bridges up to four units
[1]150-160 MPa if polished or glazed and bonded. Survival rates of 97% for crowns after 5 years, 95.5% after 9 years and 84.4% after 18 years for inlays.
[2]Requires a separate sintering furnace. Single crowns or copings can now use the 10-minute Super Speed sintering cycle.
[3]Suprinity requires a separate ceramic furnace. Suprinity FC is ready without the need of a furnace.
[4]Leucite crystals add additional reflective properties to the porcelain for enhanced aesthetics.
[5]Requires a separate ceramic furnace for crystallization.
[6]Journal of Am. Dent.Assoc, March 2012: 87.3% survival rate after 10 years with 16mm connectors on unsupported posterior bridges (no substructure).
[7]210 if polished after milling; 370 if glazed and crystallized in a ceramic oven after milling.
[8]Supported implant systems: Nobel Biocare: Replace (NP, RP, WP, 6.0), Nobel Active (NP, RP), Branemark; Straumann: SynOcta (NN, RN, WN), Bone Level (NC, RC); Astra Tech: OsseoSpeed; Friadent: Frialit / Xive; BioMet 3i: external hex, Certain; Zimmer: Tapered Screw-Vent; Medntika: M-Implant.
[9]Requires a Galileos CBVT scan as part of the process. Supported guide systems: Straumann, Camlog, Nobel Biocare: Branemark, NobelReplace Straight or Tapered, Nobel Active, Astra Tech Facilitate, and Biomet 3i Navigator. Each company has a required drill key set the doctor needs to purchase (sets range from $350 - $2500).
[10]The digital file is usually sent the lab to be mill there in this block and then invested as part of the lost-wax technique.
[11]Requires a separate sintering furnace (4.5 hour sintering cycle). To mill copings, frameworks, bars, telescopes, and attachments.
