Reconstruction of frontal bone using specific implant polyether-ether-ketone.

Defects on the craniofacial complex may result in aesthetic defects, functional damage, and psychologic consequences. Previously, surgeons showed no interest in reconstructing the operated area, but in the treatment of the problem, leaving bone contour is a secondary issue. Nowadays, area reconstruction with post-reestablishment of contour and local shape has become one of the surgeon's priorities. The use of alloplastic implants with specific digital design has been stated to be an effective technique on the treatment of craniofacial defects, reducing the need for manipulation in the intraoperative period and decreasing surgery time. Polyether ether ketone (PEEK) is a potential candidate because it is a linear polyaromatic semicrystalline polymer that combines strength, stiffness, durability, and resistance. Polyether ether ketone biocompatibility has been supported in literature, and subsequent medical applications of the material have been observed. The aim of this study was to describe a case of frontal bone defect reconstruction in which the PEEK was used as polymer material in a specific implant for the Synthes (PEEK-PSI) patient.
