Fracture resistance of abutment screws made of titanium, polyetheretherketone, and carbon fiber-reinforced polyetheretherketone [PDF]
Brazilian Oral Research, 2014 Fractured abutment screws may be replaced; however, sometimes, the screw cannot be removed and the entire implant must be surgically removed and replaced. The aim of this study was to compare the fracture resistance of abutment retention screws made of titanium, polyetheretherketone (PEEK) and 30% carbon fiber-reinforced PEEK, using an external ...

Anisotropy in polyetheretherketone films [PDF]
Journal of Nanophotonics, 2012 Optical measurements reveal the preferential orientation of nanostructures within polymer films, which results from the fabrication process including mechanical and thermal treatments. As the wavelength of the incident light is generally much larger than the characteristic dimensions of the molecular arrangement in semi-crystalline or amorphous ...

Plasma-activated polymer films for mesenchymal stem cell differentiation [PDF]
, 2014 Polyetheretherketone (PEEK) is a biomaterial utilized for spine, orthopedic and trauma implants. Its inertness prevents osseointegration, so that coatings with titanium or hydroxyapatite are required for load-bearing PEEK implants.
