A special attention has been attracted by the method of endoprosthesis replacement of temporomandibular joint. This research is devoted to an increase of surgical treatment efficiency of temporomandibular joint bone ankylosis using porous titanium nickel endoprosthesises. The analysis of distant results of application of porous nickelid titanium endoprosthesises for replacement of mandibular condylar processes in patients with temporomandibular ankylosis affects, according to anatomical specifics of affected organ, allows to make conclusion on possibility of complete restoration of lost anatomical and functional specifics of dentomaxilla apparatus. Through correspondence of hysteresis behavior of lost organ and recipient tissues to hysteresis behavior of whole complex system of endoprosthesis, the connecting tissues from implant surrounding areas grow through porous structure of implant not causing any aggressive reactions from organism side.
