Custom 3D printed titanium reconstruction plate with in-situ tissue engineering for the reconstruction and dental rehabilitation of a severely infected atrophic mandible. A review of technique

Abstract

Purpose: This article aims to introduce the novel technique of utilization of a custom 3D titanium printed reconstruction combined with in-situ tissue engineering for the reconstruction and dental rehabilitation of an infected severely atrophic mandible. Technique: A 3-staged approach was used to remove the failing implants and debride the mandible, eradicating the infection, followed by reconstruction of the severely atrophic mandible using tissue engineering supported by a customized 3D-printed titanium undercarriage and reconstruction plate for vertical and horizontal augmentation. Finally, a CAD/CAM 3D-printed surgical guide was used for optimal placement of 4 dental implants. Conclusion: A predictable and satisfactory reconstruct of a severely infected mandible with failing hardware to full dental rehabilitation and aesthetics was achieved by utilizing an amalgamation of state-of-the-art technology and tissue engineering.
