  • Restoring a tooth (CAD-CAM Ceramic) - Part 1 

    Wood, D. (Duncan); Stokes, C. (Christopher) (University of Sheffield, 2013-08)
    This video shows first stage of the production of a ceramic crown to restore a damaged tooth. In this video, the model of the tooth is scanned into the Computer-Aided-Design system (Cerec InLab) and prepared for milling. ...

  • Restoring a tooth (CAD-CAM Ceramic) - Part 2 

    Wood, D. (Duncan); Stokes, C. (Christopher) (University of Sheffield, 2013-08)
    This video shows next stage of the production of a ceramic crown to restore a damaged tooth. In this video, the core of the tooth restoration (made from alumina) is milled using a CAD-CAM process. The porous structure is ...

  • Restoring a tooth (CAD-CAM Ceramic) - Part 3 

    Wood, D. (Duncan); Stokes, C. (Christopher) (University of Sheffield, 2013-08)
    This video shows the ceramic 'build-up' stage of the production of a ceramic crown to restore a damaged tooth. In this video, ceramic powders are applied by brush to the substructure (see Videos 7 and 8). The ceramic powders ...

  • Restoring a tooth (CAD-CAM Ceramic) - Part 4 

    Wood, D. (Duncan); Stokes, C. (Christopher) (University of Sheffield, 2013-08)
    This video shows the final stage of the production of a ceramic crown to restore a damaged tooth. In this video, stain powders are applied into a glaze layer to replicate the appearance of a natural tooth. From set of ...

  • Restoring a tooth (Gold Crown) - Part 1 

    Wood, D. (Duncan); Stokes, C. (Christopher) (University of Sheffield, 2013-08)
    This video shows the first stage of the production of a cast gold crown for a damaged tooth. The crown is made on the model (See Videos 2 and 3) using wax, which will be replaced by molten gold in the lost wax casting ...

  • Restoring a tooth (Gold Crown) - Part 2 

    Wood, D. (Duncan); Stokes, C. (Christopher) (University of Sheffield, 2013-08)
    This video shows the second stage of the production of a cast gold crown for a damaged tooth. The wax template of the tooth is sprued using wax wire, then invested in a refractory investment material. The video shows the ...

  • Restoring a tooth (Gold Crown) - Part 3 

    Wood, D. (Duncan); Stokes, C. (Christopher) (University of Sheffield, 2013-08)
    This video shows the final stage of the production of a cast gold crown for a damaged tooth. The gold casting is cooled and removed from the mould. Sand blasting, an acid bath and then a series of abrasive burs are used ...
