Micro-porous composite scaffolds of photo-crosslinked poly(trimethylene carbonate) and nano-hydroxyapatite prepared by low-temperature extrusion-based additive manufacturing

Publikováno v: Polymers for Advanced Technologies. 28(10):1226-1232

Complex bony defects such as those of the orbital floor are challenging to repair. Additive manufacturing techniques open up possibilities for the fabrication of implants with a designed macro-porosity for the reconstruction of such defects. Apart fr

Fabrication of patient specific composite orbital floor implants by stereolithography

Publikováno v: Polymers for Advanced Technologies. 26(12):1433-1438

Fractures of the orbital floor are common in traffic accidents and assaults, and inadequate treatment can result in serious complications. Accurate anatomical reconstruction of the orbit using implants is the preferred treatment. Implants require deg
