Implants

PFZ implant crown, FMZir implant crown and customised Zr/Ti abutment also available in the Quest Range.

 

Abutment options for implants

Material options for implants

 

Screw-retained Restorative Options

The abutment and crown are an integrated unit. The options are:

  • Cast abutments – veneered with porcelain or composite
  • Titanium base – CAD/CAM (adhesive bases for monolithic or laminated zirconium-oxide, lithium disilicate or ceramic-composite hybrids)
  • Milled abutments – Metal (titanium or CoCr) or Zirconia

 *Titanium interface in some cases

1. Titanium interface is strong. When it is torqued down, it is unlikely to split zirconia abutments.
2. Some systems have a pure zirconia abutment direct to fixture depending on:

  • size of implant (narrow implants are unsuitable)
  • compatibility with scanners

 

Hybrid Restorations

  • Screw-retained hybrids offer a very cost-effective fixed-prosthesis option
  • Comprised of a cast of milled metal substructure layered with pink acrylic to retain acrylic denture teeth
  • Some degree of lost 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 lingual or 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
