  • Process for the fabrication of dental restorations
    Patent number: 10182895
    Abstract: Dental restorations are created by preparing a hydrocolloid mold for such dental appliances as crowns and bridges. A slurry of zirconia powder and 3-O-acryloyl-D-glucose is prepared. The slurry is gelcast in the hydrocolloid mold with polymerization of the 3-O-acryloyl-D-glucose to a green body. The green body is dried and machined to the form of the dental restoration. The polymerized 3-O-acryloyl-D-glucose is then burned from the machined green body. The remaining zirconia body in the form of the dental restoration is then sintered to form the finished device.
