PEEK

PEEK can be used for removable partial denture frameworks and clasps, with limited comparative evidence.

[1][2]

The short answer

PEEK is a polymer studied as a framework or clasp material for removable partial dentures.

What is PEEK in dentistry?

PEEK forms covered by the specification
FormUse context
Virgin PEEK polymerCovered for manufacture of surgical or dental device components[1][2]
Fabricated PEEK formCovered by the same PEEK polymer specification[1][2]

[1][2]

What does the material standard cover?

The PEEK specification covers virgin and fabricated forms used to make intracorporeal devices or components of surgical and dental devices.

Where can PEEK be used?

In removable partial dentures, PEEK has been evaluated for frameworks and clasps rather than as the teeth or gum-coloured parts of the denture.

[1]

What material is PEEK compared with?

Cobalt-chrome is the established comparator for removable partial denture frameworks. The available review compared PEEK with cobalt-chrome.

[1][2]

How did PEEK compare in the available studies?

The review found comparable fit, with retention and patient satisfaction for PEEK frameworks similar to conventional cobalt-chrome frameworks.

[1]

What remains uncertain about PEEK?

Clinical and laboratory research comparing PEEK with cobalt-chrome frameworks is still sparse, including evidence on fit, retention, clinical performance, outcomes and complications.

Frequently asked questions

Is PEEK proven to perform better than cobalt-chrome?

The available clinical and laboratory comparisons are still sparse, although the review found similar retention and patient satisfaction.
