Abutment materials

Key points

  • An abutment is a component that is intermediate between the implant and the restoration and it is usually screw-retained to the implant
  • The abutment provides the retention, support, stability and optimal position necessary for the definitive restoration
  • Titanium and zirconia are the most commonly used materials for abutment fabrication
  • Abutments can be prefabricated by the manufacturer, or custom CAD/CAM produced
