RECONSTRUCTION OF MAMDIBULAR BONE DEFECTS USING 3D SURGICAL DIGITAL PLANNING AND POLYETHERETHERKETONE (PEEK) IMPLANTS

Abstract

Aim of The Study : Reconstruction of mandibular defects after trauma or tumor resection is one of the most challenging problems facing maxillofacial surgeons. Historically various autografts and alloplastic materials 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, stiffness, durability, and environmental resistance. Recent investigations of PEEK as a biomaterial resulted in the successful treatment of cervical disk disease. We describe a case of mandibular trauma patient whose defect was reconstructed using customized PEEK implant. The treatment had excellent postoperative aesthetic and functional results without complications such as infections or extrusion.

Conclusion : Because PEEK implants are customizable, easily workable especially with help of 3D virtual planning techniques, bioinert, and nonporous, they represent an ideal alloplastic material for maxillofacial reconstruction..
