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.
• 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
• 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.
