The Use of Patient-Specific Implants in mandibular reconstruction using 3D design techniques and metal printing - clinical case –

Abstract

Reconstructions of mandibular defects after tumor excisions or explosive trauma are one of the most difficult problems facing maxillofacial surgeons. Previously, many autogenous or artificial grafts were used to reconstruct these types of defects.

As a result of the great development in 3D imaging techniques and virtual surgical planning programs, it has become possible to design the bone loss resulting from these injuries completely identical to the basic shape of the jaw to ensure the restoration of aesthetics and functionality, and then print it using biocompatibility materials through modern 3D printing techniques.

In this article, we will review the procedure for reconstruction for a large bone loss in the lower jaw resulting from a previous Ameloblastoma tumor excision through a specially designed implant PSI that is printed in 3D with titanium. The aesthetic and functional treatment results were excellent after surgery and without complications.

Conclusions: The Patient-specific implants PSI show promising results in reconstructive surgeries for bone defects of the maxillofacial and due to the excellent biocompatibility of titanium, it can be relied upon well in this type of restoration.
