Maxillofacial Reconstruction Using Polyetheretherketone Patient-Specific Implants by “Mirroring” Computational Planning

Patient-specific polyetheretherketone implants for repair of craniofacial defects.

BACKGROUND Large cranial defects represent reconstructive challenges. Polyetheretherketone (PEEK) implants are preoperatively tailored to the exact size of the defect and exhibit an excellent combination of strength, durability, and environmental resistance. This study presents our experience with patient-specific PEEK implants with computer modeling. METHODS A retrospective chart review was ...

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...

Accuracy of secondary maxillofacial reconstruction with prefabricated fibula grafts using 3D planning and guided reconstruction.

BACKGROUND We compared the pre-operative 3D-surgical plan with the surgical outcome of complex two-stage secondary reconstruction of maxillofacial defects using inserted implants in the prefabricated fibula graft. METHODS Eleven reconstructions of maxillofacial defects with prefabricated fibulas were performed using a 3D virtual planning. Accuracy of placement of the fibula grafts and dental ...

Computational Steering for Patient-Specific Implant Planning in Orthopedics

Fast and reliable methods for predicting and monitoring in-vivo bone strength are of great importance for hip joint replacement. To avoid adaptive remodeling with cortical thinning and increased porosity of the bone due to stress shielding, in a preoperative planning process the optimal implant design, size, and position has to be determined. This process involves interactive implant positionin...
