PoreStar Patient Specific Implants

A new class of implant material

PoreStar (porous polyethylene) implants are indicated for the repair or augmentation of craniofacial bone including defects caused by trauma, tumour or a congenital disorder. This includes restoration of contour in the craniofacial skeleton and cranioplasties for the protection of intracranial structures and normalisation of cerebral haemodynamics. PoreStar surgical implants are individually designed from 3D CT scans.

PoreStar Surgical Implants

Manufactured from a star to create a unique bone-like porous architecture

Porosity may permit hard and soft tissue adhesion to secure the implant

Surgeon can perform minor modifications with a scalpel and shape or feather the edges of the implant after fixation

CT and MRI compatible; radiolucent and non-magnetic for compatibility with post-operative imaging

Supplied with a BioModel (anatomical replica) with every case

Design Your Implant

Surgeon can contribute to the implant design or decide on tumour resection margins

Online implant design review service available via AnatomicsC3D

BioModel and implant prototype can be sent to the surgeon for review with the patient as part of the design process

Porous Polyethylene - Proven Clinical History

Clinical history of reconstruction and augmentation in the maxillofacial region1

Tissue ingrowth stabilises the surgical implant2

The biocompatibility standard based on long term stability and virtual lack of inflammatory response3

CT Scan Protocol
