Use of titanium nickelide based porous permeable implants for repair of postosteomyelitis mandibular defects is discussed. Five patients with mandibular defects of different location and extent were operated on. Surgical methods are described. A clinical example of using a porous permeable implant is offered. The implant designed as a mandible was used for repair of an extensive mandibular defect. Good immediate and remote results of operations indicate good prospects of using such implants.
