A cost-effective fixed-prosthesis option

Benefits

Considerations

Benefits

  • Retrievability.
  • Can evaluate underlying implant.
  • Lower maintenance.
  • More natural feel for the patient.
  • More confidence when chewing compared to removable options.
  • Great aesthetics.

Considerations

  • Can’t be removed by patient.
  • No passive fit.
  • Challenging insertion posteriorly.
  • Temporisation if repair is needed.
  • Possibility of over-loading implants if design or case selection is poor.

Use of CAD/CAM technologies for manufacturing implant superstructures produces precise yet passive fit of the milled superstructures.

Screw-retained hybrids offer a very cost-effective fixed-prosthesis option. They are comprised of a cast or milled metal substructure layered with pink acrylic to retain acrylic denture teeth. Cobalt Chrome superstructures may well be used as an alternative to veneered gold alloy.

Some degree of lost soft tissue replacement is possible. Implant positioning and angles must be favourable or angled abutments can be used to correct the angle so that screw access holes are in a lingual, palatal or occlusal position. These restorations are readily retrievable and also easily repaired. To facilitate good patient care and plaque control, careful design is important.
