Reconstruction of mandible using a computer-designed 3D-printed patient-specific titanium implant: a case report

Oral and Maxillofacial Surgery volume 25, pages103–111(2021)Cite this article

Abstract

Reconstruction of mandibular defects after trauma or tumor resection is one of the most challenging problems facing maxillofacial surgeons. Historically, various autografts and alloplastic materials have been used in the reconstruction of these types of defects. The use of individualized designed biomaterials has opened new possibilities in reconstructive surgery, and now, it is possible to use the patient’s computed tomography (CT) to construct patient-specific implants (PSIs). A case of a large mandibular tumor resection and reconstruction of the defect using a customized 3D-printed titanium implant is described. The treatment had excellent postoperative esthetic and functional results without complications.

Conclusion

Because titanium implants are customizable, easily workable especially with help of 3D virtual planning techniques, bioinert, and nonporous, they represent an ideal alloplastic material for mandibular reconstruction.
