Porous Polyethylene Implant

Porous polyethylene has been widely used for cranio-maxillofacial procedures due to its highly stable, flexible and has been shown to exhibit rapid soft-tissue and bone ingrowth. Generally, it is available as standard shape which needs to be intra-operatively contoured and manually adapted to fit the defect of each patient. In this study, a technique of producing customized porous polyethylene implant for calvarial defect reconstruction was reported. The technique began with acquiring patients data by computed tomography and was three dimensionally reconstructed using a medical imaging software. The shape of implant was then digitally designed to fit the defect based on the patients anatomy and transferred to three dimensional printing machine to fabricate the implant using proprietary polyethylene formulation as raw material. This technique can be used to cover any cranial defect size, offering similar or even better cosmetic results to standard alloplast cranioplasty while decreasing operation time. This customized porous implant can permit ingrowth of tissue to increase interface stability, implant strength and decrease the risk of infection similarly to commercial product.

Ossifying fibroma (OF) is a rare, benign, fibro-osseous lesion of the jawbone characterised by replacement of the normal bone with fibrous tissue. The fibrous tissue shows varying amount of calcified structures resembling bone and/or cementum. The central variant of OF is rare, and shows predilection for mandible among the jawbone. Although it is classified as fibro-osseous lesion, it clinically behaves as a benign tumour and can grow to large size, causing bony swelling and facial asymmetry. This paper reports a case of large central OF of mandible in a 40-year-old male patient. The lesion was treated by segmental resection of mandible. Reconstruction of the surgical defect was done using avascular fibula bone graft. Role of three-dimensional printing of jaw and its benefits in surgical planning and reconstruction are also highlighted.
