Calvarial Reconstruction With Polyetheretherketone Implants
Annals of Plastic Surgery, 2009 Despite the development of multiple cranial bone substitutes, calvarial reconstruction remains a significant challenge. Although autologous bone is preferred in many cases, its usefulness may be limited by difficulty with contouring, resorption, and donor site availability and morbidity.

Journal of Biomedical Materials Research Part B: Applied Biomaterials, 2015 AbstractPurpose: The purpose of this study was to evaluate the bone formation capability of polyetheretherketone (PEEK) and carbon fiber‐reinforced PEEK (CFR‐PEEK) implants coated with different titanium and hydroxyapatite plasma‐sprayed layers after 2 and 12 weeks. Methods: In six sheep 108 implants were placed in the pelvis.

Polyetheretherketone (PEEK) and carbon-fiber-reinforced PEEK (CFR-PEEK) have been successfully used in the field of orthopedic implants. The polymers PEEK and CFR-PEEK are resistant to fatigue strain and radiologically transparent. These have mechanical properties and are therefore suitable for a range of orthopedic applications.

Polyetheretherketone—cytotoxicity and mutagenicity in vitro
Biomaterials, 2002The results of the incubation of polyetheretherketone (PEEK) fibre material with seven different genotype variants of salmonella bacterium showed with and without an external metabolic activation system (S9) with no mutagenic or cytotoxic activity of the test material. In the so-called "plate incorporation test" in which the PEEK raw material is finely

Interlocking polyetheretherketone implant
International Journal of Oral and Maxillofacial Surgery, 2016Polyetheretherketone (PEEK) is a versatile material and is used increasingly for the correction of facial deformity. We have used bespoke implants with an interlocking mechanism to add stability and to facilitate ease of insertion in areas with difficult access.

Proceedings of the Kabardino-Balkarian State University, 2023
In this work, for the first time, comparative studies of the mechanical properties of polyetheretherketone and its copolymer based on hydroquinone and 4,4'-dihydroxybiphenyl were carried out in a wide range of test temperatures. The main regularities of the behavior of these materials in the temperature range from –65 °С to +250 °С are revealed; that ...

Tribology of polyetheretherketone
Wear, 1992Abstract A comprehensive discussion of tribological performance of polyetheretherketone is presented. It is based on experimental results obtained in a series of studies carried out in order to assess the potential of the polymer as a material for sliding and rolling contacts.
