Material Choices for Implants

Porcelain fused to metal

The long-term reliability of PFM can hide metal abutments due to layering of opaque porcelain. Various gold alloy content alloys are available. 

 

Porcelain fused to zirconia

This metal-free option is strong, aesthetic and opaque enough to hide metal abutments beneath it. 

 

IPS e.max®

Lithium disilicate offers superb aesthetics but has structural limitations. If used on metal abutment, opaquing is needed.
For optimal aesthetics anteriorly, IPS emax® should be placed over a zirconia abutment.

 

Ceramic Composite Hybrids

(eg. Lava™ Ultimate CAD/CAM Restorative, CERAMAGE®)

These offer a more resilient material and cushion the implant against occlusal forces.

Some ceramic-composite hybrids can be:

  • applied to  a titanium or cobalt chromium abutment
  • bonded onto a titanium base or
  • used as a cement-retained crown on a zirconia abutment

Hybrids can be readily repaired.

 

Fully milled zirconia

A high-strength metal-free material which is produced using a CAD/CAM process, allowing excellent marginal adaptation. Care with adjustment is required. Careful case selection is necessary to minimise wear of the opposing dentition.
