Formulation of a covalently bonded hydroxyapatite and poly(ether ether ketone) composite

open access: yesJournal of Tissue Engineering, 2018
Spinal fusion devices can be fabricated from composites based on combining hydroxyapatite and poly(ether ether ketone) phases. These implants serve as load-bearing scaffolds for the formation of new bone tissue between adjacent vertebrae.

Cryogenic Mechanical Alloying of Poly (ether ether ketone) - Polycarbonate Composite Powders for Selective Laser Sintering [PDF]

open access: yes, 1999
Mechanical alloying is a solid state processing technique traditionally used in the metallurgical industry to extend solubility limits in alloy systems. Mechanical alloying can also be used to blend polymer systems at ambient or cryogenic temperatures.

Reconstruction of frontal bone using patient specific implant poly-ether-ketone-ketone via a lateral nasal/lynch incision

open access: yesOral and Maxillofacial Surgery Cases, 2023
Trauma to the craniofacial structures can result in both functional and aesthetic defects. Mucosa lines the frontal sinus outflow tract (FSOT) from the frontal sinus to the nasal cavity and any obstruction to the flow of mucus can lead to complications ...
