Polyether Ether Ketone (PEEK) Abutments

PEEK has become the most popular material for fabricating temporary abutment. It is a beige or white colored organic polymer and a semicrystalline thermoplastic with excellent mechanical and chemical resistance properties. The Young's modulus is 3.6 GPa and its tensile strength 90-100 MPa. PEEK has a glass transition temperatures at around 143°C and melts at around 343°C (662°F).

It is highly resistant to thermal degradation as well as attack by both organic elements
and moist environments. These robust properties have made PEEK an ideal material for temporary abutment.

Technical advantages

• Ability to be sterilized without degradation in mechanical properties or biocompatibility.

• Compatibility with X-ray, magnetic resonance imaging (MRI), and computed tomography (CT) imaging without producing artifacts.

• Excellent mechanical properties such as stiffness
and durability.

• High compressive strength.

• Proven hard and soft tissue biocompatibility.

• Natural color for excellent aesthetics .
• Metal-free solution eliminates ions exchange in the mouth.
• Ease of chairside preparation and modification by dentists.

Within dentistry, PEEK polymers are used to manufacture restorative and healing abutments. Unlike the orthopedic literature, dental implant research concerning PEEK polymers is limited but what is available is promising.

For provisional restorative abutments or healing abutments, PEEK abutments are the first-line option.
