摘要：
The invention relates to medicine, and more particularly to surgical dentistry and maxillofacial surgery, and can be used in the reconstruction of mandibular defects. An endoprosthesis is prepared from titanium and an alloy thereof in the form of a three-dimensional porous body which conforms to the geometry of the defect that is to be reconstructed. A mandibular resection is carried out with the disarticulation of the temporomandibular joint. Next, an incision is made in the projection of the pectoralis major, the soft tissue flap of which is separated and drawn aside. In the muscle flap, transverse to the path of the fibres thereof, a surgical pocket is created, into which the endoprosthesis is placed. After movement within the muscle flap and rotation, the endoprosthesis is positioned with one end in the region of the articular surface of the temporomandibular joint and the other end lying along the line of the osteotomy in alignment with the remaining fragment of the lower jaw, and fixation is provided by means of bone suturing. The method allows: single-stage restoration of anatomical and aesthetic balance to the facial contours； reconstruction in the case of insufficient soft tissues to cover the endoprosthesis； complete preservation of the masticatory function of the mandible； a reduction in treatment duration and post-operative recovery time.L'invention se rapporte au domaine de la médecine, notamment de la stomatologie chirurgicale et de la chirurgie maxillaire-faciale, et peut être utilisée lors de la reconstruction de défaut de la mâchoire inférieure. Cette enoprothèse est faite de titane ou d'un alliage de celui-ci et se présente comme un corps poreux tridimensionnel reprenant la géométrie du défaut à reconstruire. La résection de la mâchoire inférieure se fait par une désarticlation de l'articulation temporo-mandibulaire. On effectue ensuite une découpe dans la projection du muscle grand pectoral dont un lambeau est séparé et mis de côté. On réalise dan
