چکیده
Single Point Incremental Forming (SPIF) is a dieless and flexible forming technology that allows performing complex shapes presents high economic payoff for low production series. In this context, research an experimental investigation of Polyether ether ketone (PEEK) sheets deformed by SPIF at room temperature, determining the influence process parameters on material formability. The performed in terms principal strains are evaluated within Limit Diagram (FLD) obtained means Nakajima tests allowing to establish limits PEEK sheet material. On other hand, results gave rise analysis formability, modes failure, force, geometry accuracy. These experiments allow assessing optimal methodologies/procedures manufacturing cranio-maxillofacial prostheses. sense, it was global study formability manufactured prostheses, as well shape accuracy, temperature roughness analysis, among others. This showed maximum attainable two prostheses were still found far away from Fracture (FFL) material, showing feasibility obtain extra safe zone. conclusion, work proved potential biomedical field using Sheet (ISF) processes combination with advanced biocompatible polymers such PEEK.

Use of customized polyetheretherketone (PEEK) implants in the reconstruction of complex maxillofacial defects.
Extensive maxillofacial defects resulting from trauma or oncologic resection present reconstructive challenges. Various autografts and alloplastic materials in conjunction with standard soft-tissue techniques have been used in the reconstruction of these types of defects. Polyetheretherketone (PEEK) is a semicrystalline polyaromatic linear polymer exhibiting an excellent combination of strength...

Computer Assisted Planning in Cranio-Maxillofacial Surgery
In cranio-maxillofacial surgery physicians are often faced with the reconstruction of massively destroyed or radically resected tissue structures caused by trauma or tumours. Also corrections of dislocated bone fragments up to the complete modeling of facial regions in cases of complex congenital malformations are common tasks of plastic and reconstructive surgeons. With regard to the individua...
متن کاملSurgical navigation in cranio-maxillofacial surgery
Introduction Surgical navigation is well-established in today’s cranio-maxillofacial surgery. However, it is often associated with extra effort for both patient and surgeon and with additional exposure to radiation due to necessary extra imaging. The cranio-orbitofacial structures are challenging with respect to accurate three-dimensional (3D) reconstruction. A virtual plan based on mirrored pa...
