Reconstruction of Mandibular Contour Using Individualized High-Density Porous Polyethylene (MedporA®) Implants Under the Guidance of Virtual Surgical Planning and 3D-Printed Surgical Templates

The mandibular contour plays a significant role in the beautiful and youthful look but the reconstruction remains a challenging problem. The objective of this study was to evaluate the use of individualized high-density porous polyethylene (Medpor(A (R))) implants for comprehensive reconstruction of mandibular contour with the aid of computer-aided design/computer-aided manufacturing (CAD/CAM). From 2010 to 2014, 12 patients with mandibular contour deformities were enrolled in our retrospective study. Mandible models and individualized surgical templates were fabricated by three-dimensional (3D) printing and Medpor(A (R)) implants were made according to the surgical templates. The Medpor(A (R)) implants were used for both unilateral and bilateral mandibular contour deformities. In four cases, simultaneous mandibular orthognathic surgery was performed with unilateral mandibular contour reconstruction. Eleven patients had a reposeful postoperative recovery with no complication. Delayed infection was shown in one patient and the Medpor(A (R)) implant was removed. All the 11 patients had the mandibular contour reconstructed satisfactorily. The technique and cases presented demonstrate the utility of Medpor(A (R)) implants with CAD/CAM in comprehensive mandibular contour reconstruction.
