[Implant-prosthetic rehabilitation of a patient with an extensive maxillofacial defect].

The paper presents a clinical case demonstrating the necessity for scarce dental implants surgery in tissues affected by multiply surgical and radiological procedures. The patient underwent 13 interventions, 4 reconstructive procedures and 3 courses of radiotherapy resulting in extensive facial defect. An orthopedic construction was fixed in a defect on mechanically stable single-stage implants with screw-retained orthopedic platform and trans-zygomatic implants on the contralateral side. The method is based on virtual diagnostics and choice of materials for 3D-prototyping of a framework to fill the defect and serve as supportive element for fixation and stabilization of obturator and facial mask.
