The use of interlocking1 PEEK patient specific facial implants (PSI) in the treatment of facial deformities, an outcome study

Introduction: Polyetheretherketone (PEEK) is a semi- crystalline linear aromatic polymer used increasingly in the correction of craniofacial deformity. PEEK is biocompatible, non-allergenic, strong, lightweight, resistant to fatigue and can be sterilized repeatedly without the degradation of its mechanical properties. PEEK can be contoured with high speed burs and fixed to bone with the use of a conventional plating system. Access, stability and soft tissue coverage are important factors for successful treatment.
