Reconstruction of frontal bone using specific implant polyether-ether-ketone.
Defects on the craniofacial complex may result in aesthetic defects, functional damage, and psychologic consequences. Previously, surgeons showed no interest in reconstructing the operated area, but in the treatment of the problem, leaving bone contour is a secondary issue. Nowadays, area reconstruction with post-reestablishment of contour and local shape has become one of the surgeon's priorit...
متن کاملLocal deformation behavior of surface porous polyether-ether-ketone.
Surface porous polyether-ether-ketone has the ability to maintain the tensile monotonic and cyclic strength necessary for many load bearing orthopedic applications while providing a surface that facilitates bone ingrowth; however, the relevant deformation behavior of the pore architecture in response to various loading conditions is not yet fully characterized or understood. The focus of this s...
متن کاملQuality of Kiwifruit Juice Clarifed by Modifed Poly(Ether Ether Ketone) Hollow Fiber Membranes
Poly(ether ether ketone) with cardo group-based (PEEK-WC) membranes, in hollow fber (HF) confguration, were prepared via the dry-wet spinning technique through the phase inversion process and used to clarify kiwifruit juice. The depectinised juice was processed according to a batch concentration confguration in selected operating conditions (transmembrane pressure, 1.6 ...
متن کاملHigh-strength, surface-porous polyether-ether-ketone for load-bearing orthopedic implants.
Despite its widespread clinical use in load-bearing orthopedic implants, polyether-ether-ketone (PEEK) is often associated with poor osseointegration. In this study, a surface-porous PEEK material (PEEK-SP) was created using a melt extrusion technique. The porous layer was 399.6±63.3 μm thick and possessed a mean pore size of 279.9±31.6 μm, strut spacing of 186.8±55.5 μm, porosity of 67.3±3.1% ...
متن کاملFriedel–Crafts Crosslinked Highly Sulfonated Polyether Ether Ketone (SPEEK) Membranes for a Vanadium/Air Redox Flow Battery
Highly conductive and low vanadium permeable crosslinked sulfonated poly(ether ether ketone) (cSPEEK) membranes were prepared by electrophilic aromatic substitution for a Vanadium/Air Redox Flow Battery (Vanadium/Air-RFB) application. Membranes were synthesized from ethanol solution and crosslinked under different temperatures with 1,4-benzenedimethanol and ZnCl2 via the Friedel-Crafts crosslin...
