PEEK – Applications in Oral Implantology and
Prosthodontics
Polyetheretherketone (PEEK) is a polyaromaticsemi-crystalline thermoplastic polymer with
mechanicalproperties favorable for bio-medical applications. Polyetheretherketone forms: PEEK-
LT1, PEEK-LT2, and PEEK-LT3 have already been applied in different surgical fields: spine surgery,
orthopedic surgery, maxillo-facial surgery etc. Synthesis of PEEK composites broadens the
physicochemical and mechanical properties of PEEK materials. To improve their osteoinductive and
antimicrobial capabilities, different types of functionalization of PEEK surfaces and changes in PEEK
structure were proposed. PEEK based materials are becoming an important group of biomaterials
used for bone and cartilage replacement as well as in a large number of diverse medical fields. The
current paper describes the structural changes and the surface functionalization of PEEK materials
and their most common biomedical applications. The possibility to use these materials in 3D printing
process could increase the scientific interest and their future development as well..
Introduction
Polyetheretherketone (PEEK) is a polyaromatic
semicrystalline thermoplastic polymer with
c h e m i c a l
f o r m u l a
(–C6H4–O–C6H4–O–C6H4–CO–) n [1] . PEEK
was commercialized for the industry in the
1980s [2]. It was proposed as a material for
biomedical application in 1998 by Invibio Ltd.
(Thornton-Cleveleys, UK). In the same year
Victrex PEEK business (Imperial Chemical
Industry, London UK) launched PEEK-OPTIMA
for long-termimplantable applications [2,3] .
Describing the properties of PEEK-optima LT1
materials we should differentiate the unfilled
PEEK biomaterial from PEEK-composites.
Implants based on the PEEK composites have
been developed as an alternative to
[4]
conventional metallic or ceramic devices . i.e.
PEEK based implants is presented below.

Clinical application of PEEK and PEEK
composites
• PEEK as an implant material
According to Wolff’s Law, the bone remodels
according to the load that has been applied to it.
Stress shielding is the reduction in volume of
the bone around an implant due to the shielding
of nor mal loads by the implant.
